  1. Official Configuration for CMS Kit with Blazor
  • CMS Kit (open source and Pro) is officially supported for MVC/Razor Pages and Blazor Server UIs.
  • For Blazor Server, you must add the CMS Kit module to your Blazor project (typically the admin app). The public website (if present) is usually MVC, but you can use Blazor for both admin and public if desired.
  • In a DDD monolith with both Blazor and MVC, ensure the CMS Kit module is referenced in both the Blazor and MVC projects if you want features available in both.
  • After adding the module, enable the required features in your GlobalFeatureConfigurator (in the Domain.Shared project):
GlobalFeatureManager.Instance.Modules.CmsKit(cmsKit =>
  {
      cmsKit.EnableAll();
  });

For CMS Kit Pro features:

GlobalFeatureManager.Instance.Modules.CmsKitPro(cmsKitPro =>
  {
      cmsKitPro.EnableAll();
  });

After enabling features, run database migrations.

  1. Widget Support and Configuration in Blazor
  • Widget support (Dynamic Widgets) is available in both MVC and Blazor UIs, but the UI experience and integration points may differ.
  • For Blazor, ensure you have the correct CMS Kit Pro packages installed and referenced in your Blazor project.
  • Widget configuration is done via the admin UI (CMS > Widgets). If the widget dropdown is empty except for "poll", it usually means no widgets are registered or enabled.
  • To register widgets, you must implement and register your widget providers in the application layer. Example:
public class MyWidgetProvider : DynamicWidgetProvider
  {
      public override void SetWidgets(IDynamicWidgetDefinitionContext context)
      {
          context.Add(new DynamicWidgetDefinition(
              name: "MyWidget",
              displayName: "My Custom Widget",
              viewComponentType: typeof(MyWidgetViewComponent)
          ));
      }
  }

Register your provider in the module:

Configure<DynamicWidgetOptions>(options =>
  {
      options.Providers.Add<MyWidgetProvider>();
  });

For Blazor, the widget's UI must be implemented as a Blazor component.

  • Place your widget provider and component in the Blazor project (or a shared project referenced by Blazor).
  1. Widget Support in Blazor Public/MVC Scenarios
  • Widgets are supported in Blazor Server UI, but the admin UI for widget management is more mature in MVC. If you use Blazor for public UI, ensure all widget components and providers are available in the Blazor project.
  • If you use MVC for public and Blazor for admin, widgets configured in admin should be available for rendering in public, provided both reference the same CMS Kit module and share the same database.
  • If you experience issues with widgets not appearing, double-check:
    • Widget providers are registered in the correct project.
    • The database is migrated after enabling features.
    • The correct CMS Kit Pro packages are installed in the Blazor project.

If you require full parity and stability for widgets in public UI, the MVC public site is currently the most stable and feature-complete. Blazor support is available but may require additional integration work, especially for custom widgets.

Answer
  • The exception you are encountering (System.MissingMethodException: Method not found: 'System.DateTime Stripe.Subscription.get_CurrentPeriodEnd()') is caused by a version mismatch between the Stripe.Net library used by the ABP Payment module and the version you have manually updated to. The ABP Payment module is tightly coupled to a specific Stripe.Net version, and updating Stripe.Net independently can break internal method calls, as you have experienced.

  • The ABP Payment module's webhook handler (_paymentRequestAppService.HandleWebhookAsync) is designed to process Stripe webhook events and update payment/subscription state accordingly. It expects the Stripe.Net types and methods it was built against. If you update Stripe.Net, ABP's code may call methods that no longer exist or have changed signatures.

  • You should only call HandleWebhookAsync for Stripe events that are relevant to payment and subscription state changes, such as:

    • checkout.session.completed
    • customer.subscription.created
    • customer.subscription.updated
    • invoice.paid
    • invoice.payment_failed
    • (and other payment-related events)

    However, the ABP Payment module is designed to internally route and process these events as needed. You do not need to filter events yourself; you should forward all Stripe webhook events to the ABP endpoint, and the module will handle the ones it supports.

  • If you must upgrade Stripe.Net due to deprecated API versions, you will need to ensure that all ABP Payment module code and dependencies are compatible with the new Stripe.Net version. Otherwise, you will encounter runtime errors like the one above.

  • For Stripe webhook endpoint configuration, ensure you are using the correct URL as per the latest ABP documentation:

yourdomain.com/api/payment/stripe/webhook

(See migration guide for details.)

  • If you encounter unsupported events or missing method exceptions, you should revert to the Stripe.Net version that matches your ABP Payment module, or contact ABP support for an updated module compatible with the latest Stripe.Net.

  • For more information on Stripe integration and webhook configuration in ABP, see the official documentation:

To reduce or turn off the frequency of health check log messages in your ABP microservice solution, you need to adjust the polling interval of the HealthChecks UI, which is responsible for querying the health endpoints and generating these logs.

By default, the polling interval is set to 10 seconds. You can increase this interval or disable the HealthChecks UI polling if you do not need it.

How to Change the Polling Interval

  1. Locate the HealthChecks UI configuration in your service (typically in HealthChecksBuilderExtensions.cs or Startup.cs):
services.AddHealthChecksUI(settings =>
   {
       settings.AddHealthCheckEndpoint("My Health Status", "/health-status");
       settings.SetEvaluationTimeInSeconds(60); // Set to 60 seconds (default is 10)
   });
  • SetEvaluationTimeInSeconds(60) changes the polling interval to 60 seconds. Adjust this value as needed.
  1. Alternatively, configure via appsettings.json:
"HealthChecksUI": {
     "EvaluationTimeOnSeconds": 60
   }

This will apply the interval globally for HealthChecks UI.

  1. If you want to completely turn off HealthChecks UI polling, you can remove or comment out the AddHealthChecksUI registration in your service configuration.

Additional Notes

  • These log messages are generated by the HealthChecks UI querying your health endpoint. Increasing the interval or disabling the UI will reduce or eliminate these logs.
  • If you are running in Kubernetes or a containerized environment, ensure that liveness/readiness probes are not set to a very low interval, as they can also generate frequent logs.

The error "NullInjectorError: No provider for InjectionToken CORE_OPTIONS!" in your ABP Angular v9.1.3 migration is caused by missing or misconfigured ABP core providers. In ABP v9+, the dependency injection system for Angular was updated to use the new Angular standalone providers API, and all ABP modules must be registered using their new provide*Config or provide* functions.

Solution

  1. Do not import ABP modules in the imports array of your components or modules.
    Instead, use the new provideAbpCore and related provider functions only in the bootstrapApplication call in your main.ts.

  2. Remove all ABP modules from the imports array in your @Component and @NgModule decorators.
    For example, in your app.component.ts, remove:

imports: [
     CoreModule,
     ThemeSharedModule,
     GdprConfigModule,
   ]

These should not be present.

  1. Ensure all ABP providers are registered in main.ts using the new provider functions.
    For example:
bootstrapApplication(AppComponent, {
     providers: [
       provideAbpCore(withOptions({ environment, registerLocaleFn: registerLocale() })),
       provideAbpOAuth(),
       provideSettingManagementConfig(),
       provideFeatureManagementConfig(),
       provideAbpThemeShared(
         withHttpErrorConfig({
           errorScreen: {
             component: HttpErrorComponent,
             forWhichErrors: [401, 403, 404, 500],
             hideCloseIcon: true,
           },
         })
       ),
       // ...other provide*Config functions
       importProvidersFrom(
         BrowserModule,
         BrowserAnimationsModule,
         ThemeLeptonXModule.forRoot(),
         SideMenuLayoutModule.forRoot()
       ),
       provideAnimations(),
       provideHttpClient(withInterceptorsFromDi()),
       provideZoneChangeDetection({ eventCoalescing: true }),
       provideRouter(routes),
     ],
   });
  1. If you comment out any provide*Config function, any dependent module will fail to resolve its options.
    For example, if you use any ABP module (like Identity, Account, etc.), you must include its corresponding provide*Config function in the providers array.

  2. Do not mix the old module-based imports with the new provider-based registration.
    All ABP modules must be registered via providers only.

Example Correction

  • Remove all ABP modules from imports in app.component.ts and any other module/component.
  • Register all needed ABP providers in main.ts only.

Reference Example

See the official ABP v9 Angular startup template for a working example:


By following these steps, the "No provider for InjectionToken CORE_OPTIONS!" error will be resolved, and your ABP Angular app will work as expected after migration.

This approach aligns with common ABP conventions, but specific official documentation for this exact scenario is not available.

To resolve the [Project Not Found] Either define a default project in your workspace or specify the project name in schematics options error when running abp generate-proxy with Angular 19 and ABP 9.2.2, follow these steps:

  1. Do NOT add defaultProject to angular.json
    The Angular 16+ workspace schema no longer supports the defaultProject property, so adding it will cause a schema validation error.

  2. Explicitly Specify the Angular Project
    Since defaultProject is not allowed, you must use the --project (or -p) option to specify your Angular project name. In your case, the project name is MYPROJECT3.

    Example:

abp generate-proxy -t ng --url https://localhost:44369 --target src/app/proxy --project MYPROJECT3 --all --force
  • Make sure the value for --project matches exactly the key under projects in your angular.json (case-sensitive).
  1. Ensure the Angular Project Structure is Correct

    • Your angular.json must have the correct structure, and the project name must be present under the projects node.
    • The sourceRoot and root properties should be correct (as in your sample).
  2. Check for Workspace Issues

    • If you still get the error, ensure you are running the command from the root of your Angular workspace (where angular.json is located).
    • If you have multiple Angular projects, always specify the correct one with --project.
  3. Update ABP CLI and Schematics

    • Make sure you are using the latest ABP CLI and @abp/ng.schematics package:
dotnet tool update -g Volo.Abp.Cli
     npm install @abp/ng.schematics --save-dev
  1. Proxy Generation Command Example
    Here is the full command you should use:
abp generate-proxy -t ng --url https://localhost:44369 --target src/app/proxy --project MYPROJECT3 --all --force

If you follow these steps and still encounter the error, double-check the spelling and casing of your project name in both the command and angular.json.

  1. The ABP Forms Module (Pro) is designed to provide a flexible, widget-like form creation experience for end users, allowing them to build and customize forms (such as event or counseling registrations) at runtime. However, as of the latest official documentation, the Forms Module does not natively support direct integration of application entities or enums as dropdown sources within the form designer UI. All form fields and dropdown options are defined within the form builder interface, and there is no built-in mechanism to bind dropdowns to existing enums or entities from your domain model. You would need to manually define dropdown options for each form, or consider extending the module if you require dynamic population from entities.

  2. The Forms Module supports storing responses and allows you to export data. For advanced processing, you can subscribe to form submission events and map responses to your own entities (such as Event or Counseling Registration tables). This is a common pattern: capture the form response, process it in an application service or event handler, and persist the structured data as needed. Naming questions programmatically for mapping is not natively supported, but you can enforce naming conventions or use custom logic in your processing layer.

  3. The abp-dynamic-form tag helper is compile-time and not intended for runtime user-driven form design. It is best suited for developer-defined forms that reflect model classes, and any changes require redeployment. Text Templating is primarily for generating text (e.g., emails) and is not suitable for interactive HTML form generation.

Recommendation:

  • For your requirements (runtime, widget-like, user-driven form design with some degree of reusability), the Forms Module (Pro) is the closest fit within ABP's offerings. You may need to extend it or implement custom logic to support entity/enum-driven dropdowns.
  • For post-processing, capturing form submission events and mapping to your own entities is a supported and recommended approach.
  • abp-dynamic-form and Text Templating are not suitable for your scenario.

Sources:

  • https://abp.io/docs/latest/modules/forms
  • https://docs.abp.io/en/abp/latest/Text-Templating

No verified source available for direct entity/enum integration in Forms Module dropdowns; this is based on current official documentation.

  • The error "There is no version found with given version: 6.0.2" indicates that the ABP Suite/CLI cannot find the project template for version 6.0.2. This typically happens if the template for the specified version was not published to the ABP template repository.

  • According to the official ABP documentation and release notes, the recommended way to create a new solution is to use the versions that are available on the ABP template server. If a specific version (such as 6.0.2) is not found, it means the template for that version was not published or is not available for download.

  • The ABP team usually publishes templates for major and minor versions, but not always for every patch version. If you require 6.0.2 specifically, but the template is missing, you will not be able to create a new project directly with that version using ABP Suite or CLI.

  • The recommended approach is:

    1. Create a new project with the closest available version (e.g., 6.0.0 or 6.0.1).
    2. After project creation, update the NuGet and NPM package versions in your solution to 6.0.2 manually.
    3. Run abp update to ensure all dependencies are aligned.
  • If your organization requires strict versioning, you must ensure the template exists for that version before starting a new project. Otherwise, use the closest available template and update dependencies as described.

  • To use the ABP Blob Storing module (such as AWS S3) in a non-ABP .NET Core Web API project, you must ensure that all required dependencies and module registrations are present. The error you are seeing indicates that the BlobStoring provider (e.g., AWS) is not fully registered, specifically the required services for IBlobContainerFactory.

  • In your custom module, you must add a dependency on the AWS Blob Storing provider module. For AWS, this is AbpBlobStoringAwsModule. You must also install the NuGet package Volo.Abp.BlobStoring.Aws and add the module dependency:

[DependsOn(typeof(AbpBlobStoringAwsModule))]
  public class NxPBlobStoringAwsModule : AbpModule
  {
  }
  • In your main module (e.g., NxPAipModule), ensure you also depend on your custom AWS module:
[DependsOn(typeof(NxPBlobStoringAwsModule))]
  public class NxPAipModule : AbpModule
  {
      public override void PreConfigureServices(ServiceConfigurationContext context)
      {
          Configure<AbpBlobStoringOptions>(options =>
          {
              options.Containers.Configure<DocumentBlobContainer>(container =>
              {
                  container.UseAws(aws =>
                  {
                      aws.Region = "eu-west-2";
                      aws.CreateContainerIfNotExists = true;
                      aws.UseClientSideEncryption = false;
                      aws.AccessKeyId = "";
                      aws.SecretAccessKey = "";
                      aws.ContainerName = "nxp-staging-1";
                  });
              });
          });
      }
  }
  • Most importantly, you must ensure that the AWS Blob Storing provider module is initialized by the ABP module system. If you only register your own modules, but not the official provider module, the required services (like IBlobContainerFactory) will not be available, resulting in the error you see.

  • In your Program.cs, when creating the application, make sure you use your main module (NxPAipModule) and that all dependencies are resolved:

using (var application = AbpApplicationFactory.Create<NxPAipModule>(options =>
  {
      options.UseAutofac();
  }))
  {
      application.Initialize();
      // ... your code
  }
  • Double-check that you have installed the following NuGet packages:

    • Volo.Abp.BlobStoring.Aws
    • Volo.Abp.BlobStoring
    • Volo.Abp.Autofac
  • If you still encounter issues, ensure that your DocumentBlobContainer class is defined as:

using Volo.Abp.BlobStoring;

  [BlobContainerName("document-blob-container")]
  public class DocumentBlobContainer
  {
  }
  • The key point is that the provider module (AbpBlobStoringAwsModule) must be included in the dependency chain and initialized by the ABP module system.

To customize the alert messages on the login page in an ABP MVC UI application (including with Account.Pro), you have several options:

  1. Change the Position and Style of Default Alert Messages:

    • ABP uses a shared "page alerts" component for displaying alerts (such as invalid credentials) on pages like login.
    • You can override the default alert component by creating a file with the same name and folder structure in your project. For LeptonX theme, the alert component is located at Themes/LeptonX/Components/PageAlerts/Default.cshtml. Copy this file into your project under the same path and modify its markup and CSS as needed to change the position and style.
    • You can also override the related C# view component (PageAlertsViewComponent.cs) if you need to change logic.
  2. Handle Alerts on the Client Side for Custom Messages:

    • The default alerts are rendered server-side, typically based on model state or exceptions.
    • To fully control the alert display (e.g., show custom messages or handle them with JavaScript), you can:
      • Suppress the default alert output in your overridden login page (Login.cshtml).
      • Add your own alert markup and use JavaScript to display messages as needed.
      • Alternatively, you can customize the login page logic in your custom LoginModel to set custom messages in the model, which you then render in your own way in the view.

Recommended Approach:

  • For most scenarios, overriding the alert component and/or the login page view is the cleanest and most maintainable way to customize both style and behavior.
  • If you want to use client-side logic, ensure you suppress or remove the default alert rendering in your custom view.

  • The error message in your screenshot, System.OperationCanceledException with a stack trace involving StackExchange.Redis.RedisCache.GetAsync, indicates that your services are unable to connect to the Redis server. This is a common issue in ABP microservice solutions, as Redis is used for distributed caching and data protection.

  • In the ABP microservice template, Redis is a required dependency. If Redis is not running, misconfigured, or unreachable, you will see these types of exceptions and your services may fail to start.

How to resolve:

  1. Ensure Redis is running:

    • If you are using Docker, make sure the Redis container is up and accessible.
    • If you are running Redis locally, verify it is running on the expected port (default: 6379).
  2. Check your connection string:

    • Open your appsettings.json or environment variables and verify the Redis connection string is correct for your environment.
    • Example:
"Redis": {
       "Configuration": "localhost:6379"
     }
  1. Kubernetes/Containerized environments:

    • If you are running in Kubernetes, ensure the Redis service is deployed and the DNS name in your configuration matches the service name in your cluster.
  2. Restart your services:

    • After fixing Redis, restart all your microservices to ensure they can connect.
  3. Check for other dependencies:

    • The microservice template also requires SQL Server and other infrastructure services. Make sure all required services are running and accessible.
