1. Solution

• Root cause: You created a minimal app with only AbpEmailingModule. The setting system throws “Undefined setting: Abp.Mailing.DefaultFromAddress” because the Email settings are defined by the Emailing module but are registered through module initialization and typically read from configuration/setting stores. In a console app created this way, you must:

  • Ensure the Emailing module is added and initialized.
  • Provide values for the email settings via appsettings.json (Settings section) or a setting store before you try to read them.
  • Make sure the virtual file system and configuration are available to the module.

• Fix (recommended simple approach): Add an appsettings.json next to your console app and load it when creating the application so ABP’s configuration system can populate settings.

using Microsoft.Extensions.Configuration;
  using Volo.Abp;
  using Volo.Abp.Emailing;
  using Volo.Abp.Settings;

  internal class Program
  {
      private static async Task Main(string[] args)
      {
          // Build configuration that includes appsettings.json
          var configuration = new ConfigurationBuilder()
              .AddJsonFile("appsettings.json", optional: true, reloadOnChange: false)
              .AddEnvironmentVariables()
              .Build();

          // Create Abp application with the configuration
          using var app = await AbpApplicationFactory.CreateAsync<AbpEmailingModule>(options =>
          {
              options.Services.ReplaceConfiguration(configuration);
          });

          await app.InitializeAsync();

          var settingProvider = app.ServiceProvider.GetRequiredService<ISettingProvider>();

          // Now this will work if setting exists in config or store
          var from = await settingProvider.GetOrNullAsync(EmailSettingNames.DefaultFromAddress);
          Console.WriteLine(from ?? "No value found");
      }
  }

appsettings.json:

{
    "Settings": {
      "Abp.Mailing.DefaultFromAddress": "noreply@yourapp.com",
      "Abp.Mailing.DefaultFromDisplayName": "Your App",
      "Abp.Mailing.Smtp.Host": "127.0.0.1",
      "Abp.Mailing.Smtp.Port": "25",
      "Abp.Mailing.Smtp.UseDefaultCredentials": "true"
    }
  }

• Alternative: Set the setting programmatically before reading it (e.g., when you don’t want to use configuration). Note: Password must be stored encrypted normally; shown here for the DefaultFromAddress only:

var settingManager = app.ServiceProvider.GetRequiredService<ISettingManager>();
  await settingManager.SetGlobalAsync(EmailSettingNames.DefaultFromAddress, "noreply@yourapp.com");

  var from2 = await settingProvider.GetOrNullAsync(EmailSettingNames.DefaultFromAddress);

• Notes:
  • If you also need to manage settings via database UI, include Setting Management modules in a real app. For a console-only test, configuration or programmatic set is sufficient.
  • Ensure you are referencing Volo.Abp.Emailing and that AbpEmailingModule is included (you already do).
  • The error “Undefined setting” means the setting definition wasn’t available to the SettingDefinitionManager at the time of resolution or no configuration was provided; wiring configuration as shown resolves it.

1. Solution

• Today, ABP provides two official web themes:
  • Basic Theme: intentionally minimal.
  • LeptonX Theme: full-featured and opinionated.
• There is no official announcement of a new, modern, lightweight theme beyond these. When you need something leaner than LeptonX but richer than Basic, ABP recommends either:
  • Customizing LeptonX via CSS variables and bundling overrides, or
  • Building your own theme package (Angular/Blazor) using Bootstrap and ABP’s theming/bundling infrastructure.

Practical options and how to proceed:

• If you stay on ABP’s web stack:
  • For Blazor/MVC:
    • Add a custom CSS file after the theme bundle to override variables (brand, primary/secondary, etc.), and register it with AbpBundlingOptions.
    • Example:

Configure<AbpBundlingOptions>(options =>
      {
          options.StyleBundles.Configure(BlazorLeptonXThemeBundles.Styles.Global, bundle =>
          {
              bundle.AddFiles("/css/custom-leptonx-overrides.css");
          });
      });

  Then, in custom-leptonx-overrides.css:

:root {
        --lpx-brand: #4f46e5;
        --lpx-primary: #4f46e5;
        --bs-primary: #4f46e5;
      }
      [data-bs-theme="dark"] {
        --lpx-brand: #8b5cf6;
      }

• For Angular:

  • Create a new Angular theme package or override styles in a global stylesheet loaded after the theme CSS. You can examine the Theme Basic package structure to replicate the minimal setup and keep it lightweight.

• Mobile (Expo/React Native):

  • ABP’s React Native option is available in Commercial (Team or higher). It’s a separate mobile template and not tied to web themes (LeptonX/Basic do not apply to React Native). For RN/Expo, you style at the component level or use a design system (e.g., NativeBase/React Native Paper/Tamagui). You consume ABP backend APIs with the provided auth/integration, but UI theming is independent of ABP web themes.

• Alternatives to ABP themes:

  • Web: You can replace Basic/LeptonX with your own Bootstrap-based or Tailwind-based theme. ABP UI packages largely rely on Bootstrap class semantics, so Bootstrap-compatible themes are easiest. Tailwind can work, but you’ll need to ensure compatibility and adjust components/layouts.
  • Mobile: Use any React Native UI library; ABP does not constrain RN theming.

• Guidance when building your own theme:

  • Angular: Review Theme Basic to understand layout tokens (Application/Account/Empty Layouts), routing outlets, and how ABP modules assume Bootstrap classes. Implement only the pieces you need to stay lightweight.
  • Blazor/MVC: Use ABP bundling to register your CSS/JS. Keep the layout razor pages/components minimal and piggyback on Bootstrap.

1. Solution

• Current behavior: In ABP Angular, the built-in abp-breadcrumb component renders items as plain text by default. This is expected; it doesn’t automatically generate router links from the Angular route tree. To make items navigable, you must provide href/routerLink explicitly when defining breadcrumb items.
• Recommended approach:
  1. If you build breadcrumbs manually in a layout/component, pass a link for each item except the last (active) one:

<abp-breadcrumb>
    <abp-breadcrumb-item [href]="'/home'" title="Home"></abp-breadcrumb-item>
    <abp-breadcrumb-item [href]="'/administration'" title="Administration"></abp-breadcrumb-item>
    <abp-breadcrumb-item title="Users"></abp-breadcrumb-item>
  </abp-breadcrumb>

• href may be any router path. If you prefer Angular bindings, wrap a custom template and use routerLink:

<abp-breadcrumb>
    <ng-container abpBreadcrumbItem>
      <a routerLink="/home">Home</a>
    </ng-container>
    <ng-container abpBreadcrumbItem>
      <a routerLink="/administration">Administration</a>
    </ng-container>
    <ng-container abpBreadcrumbItem>Users</ng-container>
  </abp-breadcrumb>

2. If you generate breadcrumbs from route data, add a data field (e.g., breadcrumb and link) to your routes and map them when rendering:

const routes: Routes = [
    { path: 'home', data: { breadcrumb: 'Home', link: '/home' }, ... },
    { path: 'administration', data: { breadcrumb: 'Administration', link: '/administration' }, ... },
    { path: 'administration/users', data: { breadcrumb: 'Users' }, ... },
  ];

// in breadcrumb component
  items = this.router.events.pipe(
    filter(e => e instanceof NavigationEnd),
    map(() => {
      const parts: { title: string; link?: string }[] = [];
      let route = this.activatedRoute.root;
      while (route) {
        const data = route.snapshot.data;
        if (data?.breadcrumb) {
          parts.push({ title: data.breadcrumb, link: data.link });
        }
        route = route.firstChild!;
      }
      return parts;
    })
  );

<abp-breadcrumb>
    <ng-container *ngFor="let i of (items | async); let last = last" abpBreadcrumbItem>
      <a *ngIf="!last && i.link" [routerLink]="i.link">{{ i.title }}</a>
      <span *ngIf="last || !i.link">{{ i.title }}</span>
    </ng-container>
  </abp-breadcrumb>

• Is it a bug? The current Angular breadcrumb control requires you to supply links; it does not infer them. That’s by design. The GitHub discussion you referenced requests linkable items by default, but until that’s implemented, use one of the patterns above.
• Workaround summary:
  • Provide href/routerLink for intermediate breadcrumb items when declaring them.
  • Or, drive breadcrumbs from Angular route data and bind routerLink for all but the last item.

1. Solution In ABP, IDataSeedContributor runs only when AbpDataSeeder is invoked. In microservice solutions, this is typically done by the DbMigrator (and sometimes by each service host during startup, depending on the template). If your custom contributor runs only when you paste the logic into the service’s existing DataSeeder class, it means your contributor is not being discovered/invoked at the time AbpDataSeeder.SeedAsync is called.

Follow these checks to ensure your custom DataSeederContributor runs at startup:

• Place the contributor in a loaded module

  • The class must be in a project/module that is actually depended on by the host you expect to run seeding in (e.g., DbMigrator or the specific service host).
  • Ensure the module is added via [DependsOn] in the relevant Host module so its services are registered.

• Implement the correct interfaces and lifetime

  • The contributor must implement: public class MyEntityDataSeedContributor : IDataSeedContributor, ITransientDependency
  • Do not use scoped/singleton here; ABP discovers transient contributors automatically.

• Ensure the DbContext and module dependencies are configured before seeding

  • If your contributor uses repositories/entities from other modules (e.g., Identity, SaaS, your module), the EF Core module must be properly configured in the DbContext and the module’s EFCore module must be depended on by the DbMigrator/host.
  • Example for Identity-related entities (when using FullAuditedEntityWithUser or relations to IdentityUser):
    • Add the proper EF Core package to the module (e.g., Volo.Abp.Identity.Pro.EntityFrameworkCore if you use Identity Pro entities).
    • In your DbContext.OnModelCreating, call the module’s Configure... method before your own mappings, e.g.: protected override void OnModelCreating(ModelBuilder builder) { base.OnModelCreating(builder); builder.ConfigureIdentityPro(); // or builder.ConfigureIdentity(); depending on your package builder.ConfigureMyModule(); }
    • Ensure your module depends on the corresponding EFCore module: [DependsOn(typeof(AbpIdentityProEntityFrameworkCoreModule))] // or AbpIdentityEntityFrameworkCoreModule

• Make sure AbpDataSeeder is actually invoked for the service where you expect seeding

  • DbMigrator: It already calls IDataSeeder.SeedAsync; your contributor will run there if discovered.
  • Service host: If you want seeding during service startup, ensure the host’s module calls IDataSeeder.SeedAsync in OnApplicationInitialization (or that the template’s seeding pipeline includes your module). A common pattern: public override async Task OnApplicationInitializationAsync(ApplicationInitializationContext context) { var seeder = context.ServiceProvider.GetRequiredService<IDataSeeder>(); await seeder.SeedAsync(); // or with a DataSeedContext as needed }

• Multi-tenancy context

  • If you need to seed for host and/or tenants, use DataSeedContext and/or ICurrentTenant correctly. For per-tenant seeding, you typically loop tenants in DbMigrator and pass tenantId via new DataSeedContext(tenantId). Your contributor’s SeedAsync should work with the given context.

• Order and conditions

  • If your contributor depends on data seeded by others, add ordering via IOrderedDataSeedContributor or check data existence safely. Also ensure your SeedAsync is idempotent.

• Verify registration and execution

  • Temporarily log inside SeedAsync.
  • Confirm the assembly containing the contributor is loaded by the host process.
  • Ensure there are no conditional registrations replacing IDataSeeder or skipping environment profiles.

Quick working example

• Contributor: public class MyEntityDataSeedContributor : IDataSeedContributor, ITransientDependency { private readonly IRepository<MyEntity, Guid> _repo;

  public MyEntityDataSeedContributor(IRepository<MyEntity, Guid> repo)
  {
      _repo = repo;
  }
  
  public async Task SeedAsync(DataSeedContext context)
  {
      if (await _repo.GetCountAsync() == 0)
      {
          await _repo.InsertAsync(new MyEntity("Sample"));
      }
  }
  

  }

• Host module ensures seeding: [DependsOn( typeof(MyServiceEntityFrameworkCoreModule), typeof(AbpEntityFrameworkCoreSqlServerModule) )] public class MyServiceHttpApiHostModule : AbpModule { public override async Task OnApplicationInitializationAsync(ApplicationInitializationContext context) { var dataSeeder = context.ServiceProvider.GetRequiredService<IDataSeeder>(); await dataSeeder.SeedAsync(new DataSeedContext(null)); // host context } }

• If using Identity Pro types in your module DbContext: [DependsOn(typeof(AbpIdentityProEntityFrameworkCoreModule))] public class MyServiceEntityFrameworkCoreModule : AbpModule { /* ... */ }

  protected override void OnModelCreating(ModelBuilder builder) { base.OnModelCreating(builder); builder.ConfigureIdentityPro(); builder.ConfigureMyService(); }

Why it worked when pasted into the template DataSeeder

• That DataSeeder class is already in the host that calls IDataSeeder.SeedAsync, so its logic runs. Your external contributor didn’t run because it either wasn’t registered (module not depended on by the host), the EF Core model for required dependencies wasn’t configured (e.g., missing ConfigureIdentity/ConfigureIdentityPro), or the host never invoked AbpDataSeeder.

1. Solution

• Goal: Let each tenant choose which email sender implementation (e.g., MailKit vs. another provider) is used when IEmailSender is called.

Approach A — Per-tenant setting + selector that resolves the right sender at runtime:

1. Define a per-tenant setting that stores the selected provider name:

public static class EmailProviderSettingNames
{
    public const string Prefix = "MyApp.Emailing";
    public const string SelectedProvider = Prefix + ".SelectedProvider"; // Values: "MailKit", "Custom"
}

Register it (e.g., in your DomainShared module):

public class MyAppSettingDefinitionProvider : SettingDefinitionProvider
{
    public override void Define(ISettingDefinitionContext context)
    {
        context.Add(
            new SettingDefinition(
                EmailProviderSettingNames.SelectedProvider,
                "MailKit", // default
                isVisibleToClients: false
            )
        );
    }
}

2. Implement your email senders (concrete classes). For example, reuse ABP MailKit sender and your custom one:

• MailKit sender is provided by Volo.Abp.MailKit (IEmailSender impl).
• Your second sender (example):

public class CustomEmailSender : IEmailSender
{
    public Task SendAsync(string to, string subject, string body, bool isBodyHtml = true) => /*...*/;
    public Task SendAsync(string from, string to, string subject, string body, bool isBodyHtml = true) => /*...*/;
    public Task SendAsync(MailMessage mail, bool normalize = true) => /*...*/;
    public Task QueueAsync(string to, string subject, string body, bool isBodyHtml = true) => /*...*/;
}

3. Register both senders as named/typed services, but do NOT wire either directly to IEmailSender:

context.Services.AddTransient<CustomEmailSender>();
// MailKit sender is added by AbpMailKitModule. Make sure to add the module dependency.

4. Create a router that implements IEmailSender and delegates to the correct concrete sender per tenant:

public class TenantAwareEmailSender : IEmailSender
{
    private readonly ICurrentTenant _currentTenant;
    private readonly ISettingProvider _settingProvider;
    private readonly IServiceProvider _serviceProvider;

    public TenantAwareEmailSender(
        ICurrentTenant currentTenant,
        ISettingProvider settingProvider,
        IServiceProvider serviceProvider)
    {
        _currentTenant = currentTenant;
        _settingProvider = settingProvider;
        _serviceProvider = serviceProvider;
    }

    private async Task<IEmailSender> ResolveActualSenderAsync()
    {
        // read per-tenant selection (falls back to host/default if not set)
        var selected = await _settingProvider.GetOrNullAsync(EmailProviderSettingNames.SelectedProvider)
                       ?? "MailKit";

        // resolve the concrete implementation
        return selected switch
        {
            "Custom" => _serviceProvider.GetRequiredService<CustomEmailSender>(),
            _ => _serviceProvider.GetRequiredService<IEmailSender>() // MailKit already registered, but beware recursion
        };
    }

    // to avoid recursion, inject MailKit concrete type instead of IEmailSender in ResolveActualSenderAsync:
}

To avoid recursion when defaulting to MailKit, register MailKit’s internal implementation separately and resolve that:

• Replace MailKit’s default registration with your own wiring:

// After AbpMailKitModule is added, capture its concrete sender type:
context.Services.AddTransient<MailKitBasedEmailSender, MailKitBasedEmailSender>(); // replace with actual type if needed
// Then override IEmailSender with your router:
context.Services.Replace(ServiceDescriptor.Transient<IEmailSender, TenantAwareEmailSender>());

If the concrete MailKit type is internal, register the original IEmailSender as a named service before replacing:

// Save the existing IEmailSender factory under a key
var original = context.Services.First(sd => sd.ServiceType == typeof(IEmailSender));
context.Services.Add(new ServiceDescriptor(typeof(IEmailSender), original.ImplementationFactory ?? original.ImplementationType!, original.Lifetime));
// Register a key-based accessor:
context.Services.AddTransient<Func<IEmailSender>>((sp) => () => (IEmailSender)ActivatorUtilities.CreateInstance(sp, original.ImplementationType!));
// Then replace IEmailSender with your router
context.Services.Replace(ServiceDescriptor.Transient<IEmailSender, TenantAwareEmailSender>());

And update ResolveActualSenderAsync to use the saved factory for the “MailKit” path to avoid self-resolution.

5. Expose the setting in UI for tenants:

• Use ABP Setting Management to allow tenants to set MyApp.Emailing.SelectedProvider (e.g., a dropdown “MailKit” / “Custom”).
• Ensure the tenant has access: ABP now controls tenant visibility of Email settings via SaaS features/permissions. In SaaS page, enable the related feature for the tenant to manage emailing settings when needed.

Approach B — Feature toggle approach (ABP Features):

• Define two mutually exclusive features (Email:UseMailKit, Email:UseCustom) as tenant-level features, and in the router use IFeatureChecker to pick the sender. This is similar to the setting approach but leverages feature management and SaaS UI out of the box.

Minimal working router example using settings and explicit DI to avoid recursion:

public class TenantAwareEmailSender : IEmailSender
{
    private readonly ISettingProvider _settings;
    private readonly CustomEmailSender _custom;
    private readonly MailKitEmailSender _mailKit; // concrete MailKit sender from Volo.Abp.MailKit

    public TenantAwareEmailSender(
        ISettingProvider settings,
        CustomEmailSender custom,
        MailKitEmailSender mailKit)
    {
        _settings = settings;
        _custom = custom;
        _mailKit = mailKit;
    }

    private async Task<IEmailSender> GetSenderAsync()
    {
        var selected = await _settings.GetOrNullAsync(EmailProviderSettingNames.SelectedProvider) ?? "MailKit";
        return selected == "Custom" ? _custom : _mailKit;
    }

    public async Task SendAsync(string to, string subject, string body, bool isBodyHtml = true)
        => await (await GetSenderAsync()).SendAsync(to, subject, body, isBodyHtml);

    public async Task SendAsync(string from, string to, string subject, string body, bool isBodyHtml = true)
        => await (await GetSenderAsync()).SendAsync(from, to, subject, body, isBodyHtml);

    public async Task SendAsync(MailMessage mail, bool normalize = true)
        => await (await GetSenderAsync()).SendAsync(mail, normalize);

    public async Task QueueAsync(string to, string subject, string body, bool isBodyHtml = true)
        => await (await GetSenderAsync()).QueueAsync(to, subject, body, isBodyHtml);
}

Then register:

[DependsOn(typeof(AbpMailKitModule))]
public class MyAppModule : AbpModule
{
    public override void ConfigureServices(ServiceConfigurationContext context)
    {
        context.Services.AddTransient<CustomEmailSender>();
        context.Services.AddTransient<MailKitEmailSender>(); // from Volo.Abp.MailKit
        context.Services.Replace(ServiceDescriptor.Transient<IEmailSender, TenantAwareEmailSender>());
    }
}

Notes:

• Per-tenant configuration is supported by ABP’s Setting Management; settings are resolved in the context of the current tenant automatically.
• If you manage email settings via the built-in Setting Management UI, give tenants the capability on the SaaS features screen (commercial) as needed.
• If you prefer a single abstraction, keep IEmailSender as the router and wire concrete senders explicitly to avoid circular DI.

1. Solution

• What you’re seeing: The log shows OpenIddict trying to persist a token/authorization entry and hitting EF Core optimistic concurrency (AbpDbConcurrencyException) during GenerateTokenContext → Protection.CreateTokenEntry. This typically happens when EF’s ChangeTracker tries to attach/update OpenIddict entities that were modified concurrently or were already being tracked differently during token issuance.
• Why your workaround helps: Overriding AbpEfCoreNavigationHelper and skipping ChangeTracker processing for OpenIddictToken prevents ABP’s navigation helper from re-attaching or fixing navigations for OpenIddictToken entities. That avoids EF Core performing unintended updates that can trigger concurrency exceptions.
• Is it recommended? Yes, this is an accepted workaround for cases where EF Core tracking interferes with OpenIddict token persistence. The same pattern has been used in prior support answers to stop the navigation helper from manipulating OpenIddict entities during token issuance. Your code is correct and safe:

using Microsoft.EntityFrameworkCore.ChangeTracking;
  using Volo.Abp.DependencyInjection;
  using Volo.Abp.EntityFrameworkCore.ChangeTrackers;
  using Volo.Abp.OpenIddict.Tokens;

  [Dependency(ReplaceServices = true)]
  [ExposeServices(typeof(AbpEfCoreNavigationHelper))]
  public class ePlusAbpEfCoreNavigationHelper : AbpEfCoreNavigationHelper
  {
      public override void ChangeTracker_Tracked(object? sender, EntityTrackedEventArgs e)
      {
          if (e.Entry.Entity.GetType() == typeof(OpenIddictToken))
          {
              return;
          }
          base.ChangeTracker_Tracked(sender, e);
      }

      public override void ChangeTracker_StateChanged(object? sender, EntityStateChangedEventArgs e)
      {
          if (e.Entry.Entity.GetType() == typeof(OpenIddictToken))
          {
              return;
          }
          base.ChangeTracker_StateChanged(sender, e);
      }
  }

• Addresses the auto logout symptom: When token persistence throws, the server still generates a JWT (GenerateIdentityModelToken) but fails storing server-side token state in some cases. That can cause the Angular app to momentarily lose continuity and re-trigger login/refresh flows. Preventing the concurrency exception stabilizes token flows and avoids visible “logout/login” flickers.
• Should this be fixed in 9.3.2 already? ABP has addressed several OpenIddict-related tracking/concurrency issues across 8.x–9.x, but depending on usage and customizations, EF’s navigation fix-ups can still race with OpenIddict’s token persistence. Keeping the ignore rule for OpenIddictToken in AbpEfCoreNavigationHelper remains a valid fix for 9.3.2.
• Additional hardening (optional):
  • If you also see concurrency logs for OpenIddictAuthorization, you can extend the guard to skip that type too:

using Volo.Abp.OpenIddict.Authorizations;
    // ...
    if (e.Entry.Entity is OpenIddictToken || e.Entry.Entity is OpenIddictAuthorization)
    {
        return;
    }

• Ensure you’re not manually attaching OpenIddict entities in your code.
• Verify your DB isolation and background jobs aren’t updating OpenIddict tables during token issuance.

Given your findings, keep your AbpEfCoreNavigationHelper replacement in place. It’s the correct, minimal, and safe solution for the concurrency you’re observing.

1. Solution You can pass the registration email to Stripe Checkout by using Payment Request ExtraProperties and a small Stripe customization point. In ABP Payment (Pro), the Stripe integration builds the Checkout Session from the PaymentRequest and allows adding metadata/customer info via options. Do this:

• Put the email on the PaymentRequest when you create it (either in your RegisterAndSubscribe workflow or by creating the PaymentRequest yourself), using ExtraProperties:

var paymentRequest = await _paymentRequestAppService.CreateAsync(
      new PaymentRequestCreateDto
      {
          Products =
          {
              new PaymentRequestProductCreateDto
              {
                  PaymentType = PaymentType.Subscription,
                  Name = "YourPlanName",
                  Code = $"tenant-{tenantId}-{planId}",
                  Count = 1,
                  PlanId = planId
              }
          },
          // carry the email for Stripe prefill
          ExtraProperties = new ExtraPropertyDictionary
          {
              { "CustomerEmail", Input.Email } // your registration email
          }
      });

  return LocalRedirectPreserveMethod("/Payment/GatewaySelection?paymentRequestId=" + paymentRequest.Id);

• Override/extend the Stripe Checkout Session creation to map ExtraProperties["CustomerEmail"] into Stripe’s session options (CustomerEmail or CustomerCreation/Customer). Create a custom Stripe payment contributor by replacing or deriving from ABP’s default Stripe request starter:

public class MyStripePaymentRequestHandler : StripePaymentRequestHandler
  {
      public MyStripePaymentRequestHandler(
          IOptions<StripePaymentOptions> options,
          // inject base deps
          ...) : base(options, /*...*/) { }

      protected override SessionCreateOptions BuildSessionOptions(PaymentRequest paymentRequest, string successUrl, string cancelUrl)
      {
          var options = base.BuildSessionOptions(paymentRequest, successUrl, cancelUrl);

          // Prefill email if provided
          if (paymentRequest.ExtraProperties.TryGetValue("CustomerEmail", out var emailObj)
              && emailObj is string email && !string.IsNullOrWhiteSpace(email))
          {
              options.CustomerEmail = email; // Stripe Checkout prefill
              // Optionally: options.Metadata = options.Metadata ?? new Dictionary<string, string>();
              // options.Metadata["abp-payment-request-id"] = paymentRequest.Id.ToString();
          }

          return options;
      }
  }

Then register your handler to replace the default:

context.Services.Replace(ServiceDescriptor.Transient<StripePaymentRequestHandler, MyStripePaymentRequestHandler>());

• If you prefer to skip the GatewaySelection page and go straight to Stripe when you only use Stripe:
  • Add Volo.Payment.Web to the UI that performs the redirect (or configure it on the HttpApi.Host as documented).
  • Detect single-gateway and redirect directly:

return LocalRedirectPreserveMethod("/Payment/Stripe/PrePayment?paymentRequestId=" + paymentRequest.Id);

Note: The default GatewaySelection page already auto-redirects when only one subscription-supported gateway is available. If you still see the selection, ensure only Stripe is enabled and subscription-supported.

• Keep required Stripe configuration:
  • In appsettings of the API Host:
    • Payment:Stripe:PublishableKey, SecretKey, WebhookSecret
    • Payment:Stripe:PaymentMethodTypes should be [] because ABP adds “card” by default.
  • Configure PaymentWebOptions (RootUrl and CallbackUrl) in the UI hosting the /Payment pages:

public override void PreConfigureServices(ServiceConfigurationContext context)
  {
      var configuration = context.Services.GetConfiguration();
      Configure<PaymentWebOptions>(o =>
      {
          o.RootUrl = configuration["App:SelfUrl"];
          o.CallbackUrl = configuration["App:SelfUrl"] + "/PaymentSucceed";
      });
  }

• About your RegisterAndSubscribeAsync path:

  • That method ends up creating a PaymentRequest and sending users to GatewaySelection. To inject the email, either:
    • Extend your MultiTenancyAppService to add ExtraProperties (like "CustomerEmail") to the PaymentRequest it creates, or
    • Switch to creating the PaymentRequest yourself (as shown above) to have full control over ExtraProperties.
  • The ABP Stripe implementation uses these data points to create the Checkout Session. With the override above, your email will prefill on Stripe.

• Notes

  • If you need additional Stripe options (locale, metadata, billing address collection, customer creation), add them in your overridden BuildSessionOptions similarly.
  • Ensure Stripe webhooks are configured so that after successful payment, the tenant’s subscription is updated accordingly.

1. Solution

• What happens with ShouldChangePasswordOnNextLogin:

  • After a successful login, if the user has IdentityUser.ShouldChangePasswordOnNextLogin = true, the Account module redirects the user to the Change Password page (not the email-based ResetPassword page). This page requires the user to be authenticated.
  • Therefore, if your global authorization rules or cookie setup cause a redirect loop, it’s typically because the user is authenticated but your allow-anonymous list or return-url handling interferes, or you didn’t whitelist the correct authenticated page.

• Pages you should allow and why:

  • Forgot Password and Reset Password are anonymous:
    • /Account/ForgotPassword
    • /Account/ResetPassword
  • Change Password requires authentication (used by ShouldChangePasswordOnNextLogin):
    • /Account/Manage/ChangePassword (MVC UI)
  • Login, Register and other account pages as you already listed.

• What to change:

  • Keep ForgotPassword and ResetPassword anonymous (as you already did).
  • Do not try to mark ChangePassword as anonymous; the user must be authenticated to use it. Instead, ensure the login succeeds and the auth cookie is established before redirecting there, and that your conventions don’t accidentally block this authenticated page.
  • If you are authorizing the whole “/” folder, do not add AllowAnonymousToFolder("/Account") globally (that would open pages that should be protected). Prefer explicit anonymous pages plus leaving authenticated pages protected.

• Recommended conventions configuration (minimal and safe):

Configure<RazorPagesOptions>(options =>
  {
      options.Conventions.AuthorizeFolder("/");

      // Anonymous account pages that must be reachable unauthenticated
      options.Conventions.AllowAnonymousToAreaPage("Account", "/Login");
      options.Conventions.AllowAnonymousToAreaPage("Account", "/Register");
      options.Conventions.AllowAnonymousToAreaPage("Account", "/ForgotPassword");
      options.Conventions.AllowAnonymousToAreaPage("Account", "/ResetPassword");
      options.Conventions.AllowAnonymousToAreaPage("Account", "/EmailConfirmation");
      options.Conventions.AllowAnonymousToAreaPage("Account", "/TwoFactor");

      // Keep Change Password authenticated (used by ShouldChangePasswordOnNextLogin)
      // Do NOT whitelist it. Path:
      // /Account/Manage/ChangePassword

      // Other truly public pages
      options.Conventions.AllowAnonymousToPage("/Error");
      options.Conventions.AllowAnonymousToPage("/PrivacyPolicy");

      // Only open payment/public folders if they are truly public
      // options.Conventions.AllowAnonymousToFolder("/Public");
      // options.Conventions.AllowAnonymousToFolder("/Payment");
      // options.Conventions.AllowAnonymousToFolder("/Payment/Stripe");
      // If you must open specific payment pages:
      // options.Conventions.AllowAnonymousToPage("/Payment/GatewaySelection");
      // options.Conventions.AllowAnonymousToPage("/Payment/Stripe/PrePayment");
      // options.Conventions.AllowAnonymousToPage("/Payment/Stripe/PostPayment");
  });

• If you still get redirected back to login repeatedly:

  • Confirm the login actually succeeds (no external cookie issues, no tenant mismatch).
  • Ensure you don’t have AllowAnonymousToFolder("/") or AllowAnonymousToFolder("/Account") combined with AuthorizeFolder("/") creating conflicting behaviors.
  • Make sure the application cookie is issued and the auth scheme matches the one used by ABP (default cookie + OIDC if used).
  • If you have custom middleware that redirects unauthenticated users, ensure it doesn’t intercept the ChangePassword redirect.

• Summary of the path to whitelist vs. not:

  • Whitelist (anonymous): /Account/ForgotPassword, /Account/ResetPassword, /Account/Login, /Account/Register, /Account/EmailConfirmation, /Account/TwoFactor.
  • Do not whitelist (must stay authorized): /Account/Manage/ChangePassword (this is where ShouldChangePasswordOnNextLogin sends the user).

1. Solution

• Current status (ABP Studio CLI 9.2.x): There is no supported way to drop a custom ZIP into ~/.abp/templates or to point ABP Studio CLI to a custom template folder. That directory is a managed download cache and is overwritten by clear-download-cache and by template updates. Overriding the built-in template download behavior is not supported.

• Recommended, supportable approaches to standardize your organization’s starting point:

  1. Create an Organization Base Solution once, and reuse it

     • Create a new solution with the official template that matches your target ABP/Commercial version (e.g., app-pro for Commercial).
     • Apply all organization-wide changes (base classes, conventions, utility code, settings, CI files, common modules/packages, theme defaults, etc.).
     • Store it in your internal Git repo as a seed project.
     • Workflow for new projects:
       • Clone the base solution as a new repo.
       • Rename namespaces, solution and project names with your own script or tooling.
       • Update Solution Configuration (if needed) and run migrations.
     • Pros: 100% control; survives upgrades; no reliance on CLI “custom templates.”
     • Notes: Keep the base solution synchronized with ABP version updates you plan to use in new projects.

  2. Package your reusable code into modules and NuGet/npm packages

     • Move base classes, common abstractions, shared UI pieces, and utilities into one or more internal ABP modules (backend NuGet packages and, if Angular, npm packages).
     • Start new projects from the official template and immediately add your internal modules via abp add-package / dotnet add package (and Angular equivalents).
     • Pros: Keeps startup templates standard and upgrades simpler; consistent reuse across solutions.

  3. ABP Suite/Studio automation (optional)

     • Use ABP Suite for repetitive CRUD scaffolding and conventions, and keep your customizations in modules and post-create scripts.
     • This does not replace a “custom template,” but reduces manual steps right after creation.

• ABP CLI vs ABP Studio CLI regarding templates:

  • The legacy ABP CLI (Volo.Abp.Cli) historically supported template source configuration in some older docs, but the current ABP Studio CLI manages and downloads official templates by version. Using the old CLI alongside Studio is not recommended for creating Commercial solutions in 9.x. The Studio CLI is the supported path for project creation and will still not load user ZIPs from ~/.abp/templates.
  • Practical guidance: Do not install or rely on the legacy CLI to inject custom templates. Use the base-solution or reusable-module approaches above.

• Answer to your specific attempts:

  • Placing app-pro-9.2.0.zip under ~/.abp/templates: Not supported; cache is controlled by the CLI and will be ignored/overwritten.
  • clear-download-cache: Correct observation; it confirms the folder is a managed cache, not an extension point.

• Minimal example of an internal module approach

[DependsOn(
      typeof(AbpIdentityApplicationModule) // and other dependencies your base module needs
  )]
  public class MyCompanyBaseApplicationModule : AbpModule
  {
      public override void ConfigureServices(ServiceConfigurationContext context)
      {
          // Configure organization-wide conventions, object mappers, settings, etc.
      }
  }

Then in a newly created project:

• Add a package reference to MyCompany.Base.Application (NuGet).
• Add DependsOn(typeof(MyCompanyBaseApplicationModule)) to the Application module.
• For UI (Angular), publish @myco/abp-ui packages and add them right after creation.

1. Solution The exception means an endpoint discovered by ApiExplorer (OpenAPI/Swagger) is coming from a conventionally-routed action. In your case, it’s the generated client proxy for Volo.Docs Admin (DocumentPdfAdminClientProxy.GeneratePdfAsync). This happens when MVC’s conventional controller discovery and the client proxy (which ApiExplorer thinks is an API surface) are both in the pipeline without proper attribute routing metadata.

Apply one of the following fixes (prefer the first):

• Fix A: Exclude client proxy types from ApiExplorer Add an MVC option to ignore ApiExplorer for the Docs Admin HttpApi Client assembly types.

using Microsoft.AspNetCore.Mvc;
  using Microsoft.Extensions.DependencyInjection;
  using Volo.Docs.Admin.HttpApi.Client; // for assembly reference

  public override void ConfigureServices(ServiceConfigurationContext context)
  {
      // ... your existing registrations

      Configure<MvcOptions>(options =>
      {
          options.Conventions.Add(new ApiExplorerVisibilityConvention(type =>
              type.Assembly == typeof(DocsAdminHttpApiClientModule).Assembly,
              isVisible: false));
      });
  }

  // helper convention
  public sealed class ApiExplorerVisibilityConvention : Microsoft.AspNetCore.Mvc.ApplicationModels.IApplicationModelConvention
  {
      private readonly Func<Type, bool> _typePredicate;
      private readonly bool _isVisible;

      public ApiExplorerVisibilityConvention(Func<Type, bool> typePredicate, bool isVisible)
      {
          _typePredicate = typePredicate;
          _isVisible = isVisible;
      }

      public void Apply(Microsoft.AspNetCore.Mvc.ApplicationModels.ApplicationModel application)
      {
          foreach (var controller in application.Controllers)
          {
              if (_typePredicate(controller.ControllerType.AsType()))
              {
                  controller.ApiExplorer.IsVisible = _isVisible;
              }
          }
      }
  }

Explanation: The Docs HttpApi Client assembly contains typed client proxies (used by your Web app to call the Docs service). They are not real MVC API controllers and shouldn’t participate in ApiExplorer/endpoint discovery. This convention hides them from ApiExplorer to prevent the “ApiExplorer enabled + conventional routing” conflict.

• Fix B: Disable ApiExplorer at controller/action level (if you have access) If a specific generated/proxy controller is being picked up, you can add:

[ApiExplorerSettings(IgnoresApi = true)]

on the controller or action. However, for generated client proxies, Fix A is more robust.

• Fix C: Ensure all discovered controllers use attribute routing (not recommended here) Converting affected controllers to attribute routing resolves the mismatch, but since the offending type is a client proxy (not meant to expose HTTP endpoints), hiding it from ApiExplorer is the correct approach.

• About MapMetrics and UseConfiguredEndpoints The crash occurs when endpoints are finalized (app.UseConfiguredEndpoints), where MVC builds its action descriptors. The above fix prevents the proxy from being treated as an MVC action, so MapMetrics and endpoint configuration can proceed normally.
