A) Install and reference the correct Elsa (Pro) integration
In your Host module (the service where Elsa will run):
[DependsOn(
typeof(Volo.Elsa.Abp.AspNetCore.AbpElsaAspNetCoreModule),
typeof(Volo.Elsa.Abp.Identity.AbpElsaIdentityModule),
typeof(Volo.Elsa.Abp.Application.AbpElsaApplicationModule),
typeof(Volo.Elsa.Abp.Application.Contracts.AbpElsaApplicationContractsModule)
)]
public class MyProjectHttpApiHostModule : AbpModule
{
public override void ConfigureServices(ServiceConfigurationContext context)
{
var configuration = context.Services.GetConfiguration();
var elsaSection = configuration.GetSection("Elsa");
context.Services.AddElsa(elsa => elsa
.UseEntityFrameworkPersistence(ef =>
DbContextOptionsBuilderExtensions.UseSqlServer(
ef, configuration.GetConnectionString("Default")))
.AddHttpActivities(elsaSection.GetSection("Server").Bind)
.AddQuartzTemporalActivities()
.AddJavaScriptActivities()
.AddWorkflowsFrom<Startup>() // optional
);
context.Services.AddElsaApiEndpoints();
Configure<AbpAntiForgeryOptions>(options =>
{
options.AutoValidateFilter = type =>
type.Assembly != typeof(Elsa.Server.Api.Endpoints.WorkflowRegistry.Get).Assembly;
});
context.Services.AddCors(cors => cors.AddDefaultPolicy(builder =>
builder.AllowAnyHeader().AllowAnyMethod().AllowAnyOrigin()
.WithExposedHeaders("Content-Disposition")));
}
public override void OnApplicationInitialization(ApplicationInitializationContext context)
{
var app = context.GetApplicationBuilder();
app.UseCors();
app.UseHttpActivities();
app.UseConfiguredEndpoints();
}
}
Add to appsettings.json:
{
"ConnectionStrings": {
"Default": "Server=...;Database=...;Trusted_Connection=False;User Id=...;Password=...;"
},
"Elsa": {
"Http": {
"BaseUrl": "https://localhost:5001"
}
}
}
B) Ensure you are creating migrations from the project that contains Elsa’s DbContext
C) If you use microservices or an external Auth Server, wire identity consistently
D) Use DbMigrator vs package manager console
E) Verify with the official sample

A) Make sure job execution is disabled at ConfigureServices (module-level), not only via appsettings
B) Remove/avoid Redis distributed lock provider registration in environments where Redis isn’t available
If you added a custom IDistributedLockProvider registration (Medallion Redis) anywhere (e.g., your HttpApi.Host, Web, or a shared infrastructure module), guard it with environment checks so it’s not registered locally: public override void ConfigureServices(ServiceConfigurationContext context) { var env = context.Services.GetHostingEnvironment(); var configuration = context.Services.GetConfiguration();
if (!env.IsDevelopment() || !string.IsNullOrEmpty(configuration["Redis:Configuration"]))
{
context.Services.AddSingleton<IDistributedLockProvider>(sp =>
{
var conn = ConnectionMultiplexer.Connect(configuration["Redis:Configuration"]);
return new RedisDistributedSynchronizationProvider(conn.GetDatabase());
});
}
}
If you don’t explicitly register a Redis provider, ABP will fall back to its default in-memory lock (sufficient for single-instance dev and won’t try to connect to Redis).
C) If you do want Redis but want startup to continue when Redis is temporarily down
D) If another module depends on AbpBackgroundJobs and starts workers
Why your “Option B” might not have worked
Minimal checklist
This response was generated by AI. If it didn’t solve your problem, feel free to post a new answer — our support team will jump in to help you soon.
Fix options (choose one):
A) Configure Redis distributed lock provider correctly
Add Medallion Redis provider registration and valid Redis connection string.
appsettings.json: { "Redis": { "Configuration": "127.0.0.1:6379" // change to your host:port or connection string } }
Module configuration: using Medallion.Threading; using Medallion.Threading.Redis; using StackExchange.Redis;
[DependsOn(typeof(AbpDistributedLockingModule))] public class YourModule : AbpModule { public override void ConfigureServices(ServiceConfigurationContext context) { var configuration = context.Services.GetConfiguration(); context.Services.AddSingleton<IDistributedLockProvider>(sp => { var conn = ConnectionMultiplexer.Connect(configuration["Redis:Configuration"]); return new RedisDistributedSynchronizationProvider(conn.GetDatabase()); }); } }
Ensure your Redis server is running and reachable from the app container/host. If your Redis requires password or user, use a full StackExchange.Redis connection string, e.g. host:port,password=yourpw,abortConnect=false. The abortConnect=false (or AbortOnConnectFail=false) allows the multiplexer to keep retrying during transient startup.
B) Disable background jobs (removes need for distributed lock at startup)
C) Use a different lock provider (e.g., database) or defer lock provider registration in environments without Redis If you can’t run Redis in dev/staging, either:

Fix it by injecting IConfiguration (or using GetRequiredService<IConfiguration> from the service provider) and using it where _configuration is referenced.
Option A: Constructor inject IConfiguration in the seeder
Example:
using Microsoft.Extensions.Configuration;
using Volo.Abp.DependencyInjection;
using Volo.Abp.Data;
namespace Microservicev10.IdentityService.Data.OpenIddict;
public class OpenIddictDataSeeder : IDataSeedContributor, ITransientDependency
{
private readonly IConfiguration _configuration;
// other injections...
public OpenIddictDataSeeder(
IConfiguration configuration
/* other dependencies */
)
{
_configuration = configuration;
// assign others...
}
public async Task SeedAsync(DataSeedContext context)
{
// Use _configuration["OpenIddict:Applications:MyClient:RootUrl"] etc.
// Your existing seeding logic...
}
}
Option B: Resolve IConfiguration on demand If you already have IServiceProvider injected, resolve configuration when needed:
public async Task SeedAsync(DataSeedContext context)
{
var configuration = _serviceProvider.GetRequiredService<IConfiguration>();
var rootUrl = configuration["OpenIddict:Applications:MyClient:RootUrl"];
// ...
}
Common places that use _configuration in OpenIddict seeders:
Also ensure the seeder runs:

Architecture to meet your requirements
Steps
GlobalFeatureManager.Instance.Modules.CmsKit(cmsKit =>
{
cmsKit.EnableAll(); // or enable specific CmsKit features
});
GlobalFeatureManager.Instance.Modules.CmsKitPro(cmsKitPro =>
{
cmsKitPro.EnableAll(); // or enable specific Pro features like Newsletter, Contact Form, URL Forwarding, Poll, etc.
});
- Add EF Core migration and update the database after enabling features.
Configure tenant resolution for the Public Website
Anonymous/public access
[AllowAnonymous]
public class MyPublicController : AbpController

Apply the checklist below. It mirrors the verified ABP guidance and fixes most AAD external login issues.
A. Ensure the correct external SignIn scheme and claim mapping
private void ConfigureExternalProviders(ServiceConfigurationContext context)
{
var configuration = context.Services.GetConfiguration();
context.Services.AddAuthentication()
.AddOpenIdConnect("AzureOpenId", "Azure Active Directory OpenId", options =>
{
options.Authority = "https://login.microsoftonline.com/" + configuration["AzureAd:TenantId"] + "/v2.0/";
options.ClientId = configuration["AzureAd:ClientId"];
options.ClientSecret = configuration["AzureAd:ClientSecret"];
options.ResponseType = OpenIdConnectResponseType.CodeIdToken; // or Code
options.CallbackPath = configuration["AzureAd:CallbackPath"]; // e.g. /signin-azuread-oidc
options.RequireHttpsMetadata = true; // keep true in Azure
options.SaveTokens = true;
options.GetClaimsFromUserInfoEndpoint = true;
// Important for ABP external logins:
options.SignInScheme = IdentityConstants.ExternalScheme;
options.Scope.Add("email");
options.ClaimActions.MapJsonKey(ClaimTypes.NameIdentifier, "sub");
// If you need to override RedirectUri in prod (behind reverse proxy):
if (context.Services.GetHostingEnvironment().IsProduction())
{
options.Events = new OpenIdConnectEvents
{
OnRedirectToIdentityProvider = ctx =>
{
// Use your public https URL + CallbackPath, if Azure is terminating TLS/proxying.
// Example: https://your-public-domain/signin-azuread-oidc
ctx.ProtocolMessage.RedirectUri = configuration["AzureAd:RedirectToIdentityProviderUri"];
return Task.CompletedTask;
}
};
}
});
}
B. Validate Redirect URI and CallbackPath consistency
C. Ensure email scope is requested
D. Behind reverse proxy/Azure App Service specifics
E. Cookie/SameSite considerations
F. Quick diagnostics
G. Multi-tenant or dynamic provider settings (if applicable)

Fix your account/organization linkage
Implementing cart → checkout → payment → access granting

If you can’t use the Commercial module:
Example event handler to grant access after payment:
public class OrderPaidEventHandler : ILocalEventHandler<OrderPaidEvent>, ITransientDependency
{
private readonly IRepository<Enrollment, Guid> _enrollmentRepo;

_enrollmentRepo = enrollmentRepo;

}
