To create a new microservice in an ABP microservice solution using ABP Studio, the default and currently supported approach is to use the "no layers" (service_nolayers) template. ABP Studio does not provide a built-in option to generate a new microservice with a full N-Layer (Domain, Application, EntityFramework, etc.) structure directly from the UI.

If you require an N-Layer structure for your new service, you have two main options:

1. Manual Creation:

   • Manually create the required projects (e.g., .Domain, .Application, .EntityFrameworkCore, .HttpApi, etc.) for your new service.
   • Follow the structure of existing layered microservices in your solution.
   • Register dependencies and configure your solution as needed.

2. Custom Template:

   • Use the ABP CLI to generate a new layered service/module outside the solution, then add it manually to your microservice solution.
   • Example CLI command for a layered module:

abp new MyCompany.MyService -t module

• Move the generated projects into your solution and update references/configuration.

Currently, ABP Studio's microservice addition wizard only supports the "no layers" template for new services. For more details and updates, refer to the official documentation below.

解决方案如下：

1. 你的 AuthServer 只注册了 AbpIdentityProEntityFrameworkCoreModule，但没有注册 AbpIdentityProApplicationModule 或 AbpIdentityApplicationModule，导致 IIdentityUserAppService 没有被依赖注入容器注册。

2. 你需要在 AuthServer 的模块依赖中添加 Identity 的 Application 层模块依赖。商业版推荐添加 AbpIdentityProApplicationModule，开源版添加 AbpIdentityApplicationModule。例如：

[DependsOn(
    // ... 其他依赖
    typeof(AbpIdentityProEntityFrameworkCoreModule),
    typeof(AbpIdentityProApplicationModule) // 商业版
    // typeof(AbpIdentityApplicationModule) // 开源版
)]
public class QRSPCAuthServerModule : AbpModule
{
}

3. 如果你只添加了 EntityFrameworkCore 层，Application 层的服务（如 IIdentityUserAppService）不会被注册，依赖注入会报错。

4. 确认你的 NuGet 包已正确引用 Volo.Abp.Identity.Pro.Application（商业版）或 Volo.Abp.Identity.Application（开源版）。

5. 重新编译并运行，IIdentityUserAppService 就可以被正常注入和使用。

• The error you are encountering (System.ObjectDisposedException related to Autofac and Blazorise) after upgrading to ABP 9.3.1 with Blazor Server is typically caused by a mismatch or incompatibility between the Blazorise package versions and the ABP/Blazor project dependencies. This is especially common after major upgrades.

To resolve this issue, follow these steps:

1. Update Blazorise Packages
   Ensure that all Blazorise-related NuGet packages in your solution are updated to the latest versions compatible with .NET 8/9 and ABP 9.x. You can do this via NuGet Package Manager or by editing your .csproj files.

2. Clean and Rebuild

   • Delete the bin and obj folders in all projects.
   • Rebuild the solution to clear any cached assemblies.

3. Check for Duplicate Registrations

   • Make sure you are not registering Blazorise services (e.g., AddBootstrap5Providers, AddFontAwesomeIcons) in both your Blazor and Host projects. Shared registrations should be in a shared module or only in the host for Blazor Server.

4. Update ABP and Run Bundle

   • Run abp update in your solution root to update all ABP-related packages.
   • Run abp bundle to update static assets.

5. Review Dependency Injection Configuration

   • Ensure that your DI registrations for Blazorise and other UI components are correct and not duplicated or missing.

6. Restart Development Environment

   • Sometimes, Visual Studio or your IDE may cache old assemblies. Restart your IDE after the above steps.

If the problem persists, try creating a new ABP Blazor Server solution with the same version and compare the package versions and startup configuration.

• With ABP 9.x and Angular 20, the LeptonX theme and its layout system have changed. In recent versions, the side menu and layout components were refactored, and some component names were updated. If your sidebar is missing, it is likely due to outdated imports or configuration.

Steps to resolve:

1. Update LeptonX Theme Packages

   • Ensure you are using the latest compatible version of @abp/ng.theme.lepton-x (for open-source) or @volosoft/abp.ng.theme.lepton-x (for commercial) that matches your ABP version.

2. Update Angular Module Imports

   • In your app.module.ts, remove any old Lepton/LeptonX theme modules and import the new ones:

import { ThemeLeptonXModule } from '@abp/ng.theme.lepton-x';
     import { SideMenuLayoutModule } from '@abp/ng.theme.lepton-x/layouts';

     @NgModule({
       imports: [
         // ...
         ThemeLeptonXModule.forRoot(),
         SideMenuLayoutModule.forRoot(),
       ],
       // ...
     })
     export class AppModule {}

• For commercial: use @volosoft/abp.ng.theme.lepton-x and AbpSideMenuLayoutModule.

3. Check angular.json Styles
   • Remove any direct Bootstrap CSS import. Add the LeptonX CSS and Bootstrap Icons:

"styles": [
       "node_modules/@volo/ngx-lepton-x.lite/styles/sidemenu-layout.min.css",
       "node_modules/bootstrap-icons/font/bootstrap-icons.css"
     ]

• For commercial, use the corresponding @volosoft/ngx-lepton-x paths.

4. Migration Changes

   • In ABP 7.0+, the layout component names changed:
     • eThemeLeptonXComponents.Navbar → eThemeLeptonXComponents.Toolbar
     • eThemeLeptonXComponents.Sidebar → eThemeLeptonXComponents.Navbar
   • If you use replaceable components, update their references as per the new naming.

5. Clear Cache and Rebuild

   • Delete node_modules, run npm install or yarn, and rebuild your project.

6. Verify Layout Usage

   • Ensure your main layout uses the correct dynamic layout selector for LeptonX. If you customized layouts, update them to use the new component structure.

If you still see an empty layout:

• Double-check that you are not mixing old and new LeptonX modules.
• Compare your app.module.ts and angular.json with a fresh ABP 9.x Angular template using LeptonX.

To add a custom "Create Language Text" button to the Language Texts page in your ABP MVC (Razor Pages) application, follow these steps:

1. Extend the Page Toolbar with a Custom Button

In your Web module's ConfigureServices method, use the ABP Page Toolbar Extensions to add a new button to the Language Texts page toolbar:

Configure<AbpPageToolbarOptions>(options =>
{
    options.Configure<Volo.Abp.LanguageManagement.Web.Pages.LanguageManagement.LanguageTexts.IndexModel>(toolbar =>
    {
        toolbar.AddButton(
            LocalizableString.Create<YourResource>("CreateLanguageText"),
            icon: "plus",
            id: "CreateLanguageTextButton",
            type: AbpButtonType.Primary
        );
    });
});

• Add the "CreateLanguageText" string to your localization files.

2. Add the Modal or Redirect Logic

• In your Index.cshtml (or the corresponding Razor Page), add JavaScript to handle the button click. You can use ABP's modal helpers or redirect to a custom create page.

Example for opening a modal (using Bootstrap/ABP modal):

$(function () {
    $('#CreateLanguageTextButton').click(function () {
        abp.modals.open({
            title: 'Create Language Text',
            size: 'lg',
            bodyUrl: '/LanguageManagement/LanguageTexts/CreateModal'
        });
    });
});

3. Create the Modal or Create Page

• Add a new Razor Page (e.g., CreateModal.cshtml) under /Pages/LanguageManagement/LanguageTexts/.
• The page should contain a form with fields: Resource Name (dropdown), Culture Name (dropdown), Name (key), and Value.
• On form submission, call the backend API (PUT /api/language-management/language-texts) using AJAX or ABP's form helpers.

Example form (simplified):

<form id="createLanguageTextForm">
    <!-- Resource Name dropdown -->
    <!-- Culture Name dropdown -->
    <!-- Name (key) input -->
    <!-- Value input -->
    <button type="submit" class="btn btn-primary">Save</button>
</form>
<script>
    $('#createLanguageTextForm').submit(function (e) {
        e.preventDefault();
        // Collect form data
        // Call the API using abp.ajax or $.ajax
    });
</script>

4. Backend API Usage

• Use ILanguageTextAppService.UpdateAsync() in your backend to create or update the language text.
• The API endpoint is already available in ABP Language Management module.

5. Reusable Components

• There is no built-in ABP modal for creating language texts, but you can reuse ABP's form and modal helpers for consistency.
• For reference on converting modals to pages or customizing modals, see the community article below.

To roll back (revert) migrations in a separate tenant database context in an ABP solution with separate tenant schemas, you need to use Entity Framework Core's migration tools, targeting the correct DbContext and connection string for each tenant database.

Development Environment

1. Identify the Tenant DbContext and Connection String

   • Use your TenantDbContext (e.g., YourAppTenantDbContext).
   • Use the tenant's specific connection string.

2. Use EF Core CLI to Roll Back a Migration

   • Open a terminal in your .EntityFrameworkCore project directory.
   • Run the following command to revert to a specific migration (replace MigrationName and YourAppTenantDbContext):

dotnet ef database update MigrationName --context YourAppTenantDbContext --connection "YourTenantConnectionString"

• To revert all migrations (reset database), use:

dotnet ef database update 0 --context YourAppTenantDbContext --connection "YourTenantConnectionString"

• You can also use the dotnet ef migrations remove command to remove the last migration (from code), but this does not affect the database itself.

3. Repeat for Each Tenant
   • Run the above command for each tenant database you want to roll back.

Production Environment (Containers)

• Automated Rollback

  • In production, you typically automate migrations using a tool or script (e.g., a custom migrator or CI/CD pipeline).
  • To roll back, run the same dotnet ef database update command inside the container, targeting the tenant's connection string.
  • You may need to exec into the running container or run a migration job/container with the correct environment variables.

• DbMigrator Application

  • If you use ABP's .DbMigrator app, you must extend it to support rolling back migrations, as by default it only applies the latest migrations.
  • You can add logic to call Database.Migrate(targetMigration) or use EF Core APIs to revert to a specific migration.

Notes

• EF Core does not support "down" migrations for all operations (some changes may not be reversible).
• Always back up your databases before rolling back migrations, especially in production.

Example Command

dotnet ef database update PreviousMigrationName --context YourAppTenantDbContext --connection "Host=...;Database=tenantdb;Username=...;Password=..."

To enable synchronous communication between services in ABP (such as calling DocumentService from InvoiceService), you must reference the correct modules and configure dependencies as described in the official guide.

Based on your error, the problem is that the dependency injection system cannot resolve the IDocumentsAppService in your InvoiceManager. This typically means the HttpApi.Client module for DocumentService is not referenced or registered properly in InvoiceService.

Here is the correct approach, following the official documentation:

1. Reference the HttpApi.Client Project
   • In your InvoiceService.Application (or equivalent) project, add a reference to the DocumentService.HttpApi.Client project:

<ProjectReference Include="..\..\..\document\src\DocumentService.HttpApi.Client\DocumentService.HttpApi.Client.csproj" />

2. Add Module Dependency
   • In your InvoiceServiceApplicationModule, add a dependency on the DocumentServiceHttpApiClientModule:

[DependsOn(
         typeof(DocumentServiceHttpApiClientModule)
     )]
     public class InvoiceServiceApplicationModule : AbpModule
     {
         // ...
     }

• The guide's reference to ProductServiceHttpApiClientModule is just an example. You should use the actual module class from your DocumentService.HttpApi.Client project, which is typically named DocumentServiceHttpApiClientModule.

3. Configure Remote Service Endpoints
   • In your InvoiceService.HttpApi.Host's appsettings.json, configure the remote service endpoint for DocumentService:

"RemoteServices": {
       "Default": {
         "BaseUrl": "https://your-document-service-url/"
       }
     }

4. Do Not Use Contracts Module for Remote Calls

   • The Contracts module (DocumentServiceContractsModule) is for sharing DTOs and interfaces, not for enabling remote HTTP calls. You must use the HttpApi.Client module for remote service proxies.

5. Rebuild and Restart

   • After making these changes, rebuild your solution and restart the services.

If you follow these steps and ensure the correct module is referenced and registered, the DI system will be able to resolve IDocumentsAppService as a dynamic HTTP proxy, and your error should be resolved.

To dynamically set the RootUrl in a SaaS (multi-tenant, multi-domain) scenario with ABP Framework, you should use the domain/subdomain tenant resolver and configure your application to use placeholders in your configuration files. This allows the application to resolve the tenant and domain at runtime, ensuring the correct RootUrl is used for each tenant.

Step-by-step Solution

1. Use Placeholders in Configuration In your appsettings.json or relevant configuration, use the {0} placeholder for tenant-specific domains:

"App": {
     "SelfUrl": "https://{0}.yourdomain.com",
     "SelfUrlWithoutTenant": "https://yourdomain.com"
   }

2. Configure Tenant Resolver in Startup In your module's ConfigureServices method, add the domain tenant resolver:

Configure<AbpTenantResolveOptions>(options =>
   {
       options.AddDomainTenantResolver(configuration["App:SelfUrl"]);
   });

3. Dynamically Set RootUrl at Runtime When you need to set the RootUrl (e.g., for payment callbacks), use the current request's host to build the URL:

services.Configure<PaymentWebOptions>(options =>
   {
       var httpContextAccessor = services.BuildServiceProvider().GetRequiredService<IHttpContextAccessor>();
       var currentDomain = httpContextAccessor.HttpContext?.Request.Host.Value;
       options.RootUrl = $"https://{currentDomain}";
       options.CallbackUrl = $"https://{currentDomain}/Payment/Success";
   });

Make sure to register IHttpContextAccessor in your DI container:

services.AddHttpContextAccessor();

4. Frontend (if applicable) For Angular or Blazor, use the {0} placeholder in your environment or appsettings files, and replace it at runtime based on the current domain.

Notes

• This approach ensures each tenant's domain is used for RootUrl and callback URLs.
• The {0} placeholder is replaced by the tenant name/domain at runtime by ABP's multi-tenancy infrastructure.

To resolve the "error validating authorization_endpoint in discovery document" and ensure your ABP Angular application works with your backend in an environment where all internal traffic is HTTP but public endpoints are HTTPS, you must ensure that all URLs in your OpenID Connect discovery document (/.well-known/openid-configuration) use HTTPS. The Angular OAuth2/OIDC client requires all endpoints (issuer, authorization_endpoint, token_endpoint, etc.) to be HTTPS when requireHttps is true (which is the default in production).

Solution Steps

1. Kestrel/Reverse Proxy Configuration
   • Even if your app service uses HTTP internally, you must ensure that the URLs generated in the discovery document are HTTPS. This is typically handled by forwarding headers from your reverse proxy (like Azure App Service or Nginx).
   • In your Program.cs or Startup.cs, add the following to enable forwarded headers:

app.UseForwardedHeaders(new ForwardedHeadersOptions
     {
         ForwardedHeaders = ForwardedHeaders.XForwardedProto | ForwardedHeaders.XForwardedFor
     });

• Ensure your reverse proxy (Azure App Service) is configured to forward the X-Forwarded-Proto header.

2. AppSettings Configuration
   • Set App.SelfUrl to your public HTTPS URL:

"SelfUrl": "https://dev-configurator-api.mtgcorp.com"

• Set App.AngularUrl to your deployed Angular app's public URL (not localhost for production):

"AngularUrl": "https://dev-configurator.mtgcorp.com"

• Set App.CorsOrigins to include your Angular app's public URL:

"CorsOrigins": "https://*.mtgcorp.com"

• Set App.RedirectAllowedUrls to your Angular app's public URL:

"RedirectAllowedUrls": "https://dev-configurator.mtgcorp.com"

• For local development, you can add http://localhost:4200 to these lists, but for production, only use HTTPS URLs.

3. RemoteServices Configuration
   • Set RemoteServices.Default.BaseUrl to your backend's public HTTPS URL:

"RemoteServices": {
       "Default": {
         "BaseUrl": "https://dev-configurator-api.mtgcorp.com/"
       }
     }

• Do the same for any other remote services.

4. AuthServer Configuration
   • Set AuthServer.Authority to your public HTTPS URL:

"Authority": "https://dev-configurator-api.mtgcorp.com"

• Set RequireHttpsMetadata to true for production.

5. Regenerate Discovery Document

   • After making these changes, restart your backend. The discovery document at https://dev-configurator-api.mtgcorp.com/.well-known/openid-configuration should now show all endpoints as HTTPS.

6. Angular Environment

   • In your Angular environment.prod.ts, set the OAuth config to use the HTTPS backend URL for issuer and endpoints.

Summary Table

| Setting | Value (Production) | |---------------------------------|----------------------------------------------------| | App.SelfUrl | https://dev-configurator-api.mtgcorp.com | | App.AngularUrl | https://dev-configurator.mtgcorp.com | | App.CorsOrigins | https://*.mtgcorp.com | | App.RedirectAllowedUrls | https://dev-configurator.mtgcorp.com | | RemoteServices.Default.BaseUrl | https://dev-configurator-api.mtgcorp.com/ | | AuthServer.Authority | https://dev-configurator-api.mtgcorp.com | | AuthServer.RequireHttpsMetadata| true |

Note: If you need to support local development, add http://localhost:4200 to CORS and RedirectAllowedUrls, but never use HTTP in production.

To change the configuration (such as API URLs) of an ABP Blazor WebAssembly application after publishing—especially in a Docker or cloud environment—you should use environment-specific configuration files that can be overridden at runtime.

Key Solution Steps:

1. Use environment-specific JSON files:

   • Place appsettings.{ENVIRONMENT}.json (e.g., appsettings.Production.json) in the wwwroot folder of your Blazor WASM project.
   • At runtime, the Blazor app will fetch the appropriate configuration file based on the environment.

2. Override configuration at runtime:

   • In Docker or Kubernetes, mount a volume or use a ConfigMap/Secret to provide the correct appsettings.{ENVIRONMENT}.json file at container startup.
   • This allows you to change URLs and other settings without rebuilding the image.

3. Static file serving order:

   • Ensure app.UseStaticFiles() is called before app.MapAbpStaticAssets() in your host project’s Program.cs or Startup.cs.
   • Example:

app.UseStaticFiles();
     app.MapAbpStaticAssets();

4. Disable Blazor compression if needed:
   • If you need to disable compression for easier file replacement, add the following to your .csproj:

<BlazorEnableCompression>false</BlazorEnableCompression>

• This ensures files like appsettings.json are not compressed and can be replaced or read as plain text.

5. UseStaticFilesForPatterns:
   • If you want to serve only specific files, you can use:

app.UseStaticFilesForPatterns("appsettings*.json");

6. Reload configuration:
   • Blazor WASM reads configuration at startup. If you replace the config file, you must reload the app in the browser to pick up changes.

Summary:
For Dockerized or cloud deployments, provide the correct appsettings.{ENVIRONMENT}.json at runtime via volume mounts or similar mechanisms. Ensure static files are served correctly and compression is disabled if you need to override files after publishing.
