For the Blazor Web App (Fullstack) template in ABP Framework, the current solution template does not provide an option to "Separate Authentication Server" like the Blazor WebAssembly template does. In the Blazor Web App layered template, the authentication server is integrated into the HttpApi.Host by default unless you select the "Tiered" option, which physically separates the Web and HTTP API layers (and may also separate the Auth Server).
If you want a single deployment output where the Blazor WebApp and HttpApi.Host (including the Auth Server) are together, simply do NOT check the "Tiered" option when creating your solution. This will generate a layered solution with the Auth Server integrated into the HttpApi.Host, matching your requirement.
Currently, there is no "Separate Authentication Server" checkbox for the Blazor Web App template. The separation is only controlled by the "Tiered" option. If you want the same behavior as Blazor WebAssembly (where you can choose to separate or not), you must use the layered template and leave "Tiered" unchecked.

In ABP microservice solutions deployed on Kubernetes, it is best practice for internal service-to-service communication to use Kubernetes internal DNS/service names (e.g., http://identity-service:port) rather than exposing every microservice via Ingress. Only the gateway(s) and AuthServer should be exposed externally.
For authentication to work correctly through the WebGateway, ensure the following:
You do NOT need to expose all microservices via Ingress. Internal Kubernetes services are sufficient and recommended for security.
If authentication fails only for internal calls, double-check that:
Example configuration for internal service communication:
"RemoteServices": {
"Identity": {
"BaseUrl": "http://identity-service" // Kubernetes service name
}
},
"AuthServer": {
"Authority": "https://authserver.yourdomain.com", // Public URL, even for internal calls
"RequireHttpsMetadata": false
}

To resolve the Content-Security-Policy (CSP) error blocking image loading (such as favicon.ico) in your ABP Angular project, you need to adjust the CSP headers to allow images from the required sources.
By default, ABP's Security Header Middleware may set a restrictive CSP like default-src 'none', which blocks all resources unless explicitly allowed. This causes the browser to block images, including the favicon.
Solution:
Locate the CSP configuration in your server-side (API or host) project. This is typically set in the ConfigureServices or OnApplicationInitialization method, or in the appsettings.json under SecurityHeaders.
Update the CSP to allow images from your domain. For example, in C#:
app.UseAbpSecurityHeaders(options =>
{
options.ContentSecurityPolicy = "default-src 'self'; img-src 'self' data:;";
});
'self' allows images from the same origin.data: allows inline images (such as base64-encoded favicons).appsettings.json for configuration, update the relevant section:"SecurityHeaders": {
"ContentSecurityPolicy": "default-src 'self'; img-src 'self' data:;"
}
This will resolve the error and allow the favicon and other images to load.

To enforce external login (e.g., BankID) for specific actions in ABP, the recommended approach is to customize the login flow by overriding the LoginModel and the login page, as you have done. This is the standard and supported way in ABP to control authentication logic, since the login UI and logic are encapsulated in the Account module and can be overridden as needed.
OnGetAsync method in your custom LoginModel, you can check for a specific query parameter (e.g., bankid=true) and trigger the external login flow for BankID. This is the correct extensibility point provided by ABP.[ExposeServices(typeof(Volo.Abp.Account.Public.Web.Pages.Account.LoginModel))]
public class LoginModel : Volo.Abp.Account.Public.Web.Pages.Account.LoginModel
{
// ... constructor ...
public override Task<IActionResult> OnGetAsync()
{
return ShouldForceBankIdLogin()
? base.OnPostExternalLogin(MachineRegistryConsts.BankIdLoginProviderName)
: base.OnGetAsync();
}
private bool ShouldForceBankIdLogin()
{
if (ReturnUrl.IsNullOrEmpty())
{
return false;
}
var decodedReturnUrl = HttpUtility.UrlDecode(ReturnUrl);
return decodedReturnUrl.Split("&").Any(p => p.Equals("bankid=true", StringComparison.OrdinalIgnoreCase));
}
}
navigateToBankIdLogin() {
this.authService.navigateToLogin({
prompt: 'login',
bankid: true
});
}
The double-click issue is likely due to the login page being loaded first, and then the external login being triggered on the next navigation. This happens because the first navigation loads the login page, and only after the OnGetAsync logic runs does it redirect to the external provider.
LoginModel is the recommended and supported way in ABP to enforce external login for specific actions.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.
Thank you for your detailed suggestion regarding the minification of LeptonX theme CSS files. Your observation is valid: serving unminified CSS can negatively impact performance metrics and user experience.
Currently, ABP Framework provides a bundling and minification system that is designed to optimize CSS and JavaScript files automatically in production environments. However, if the LeptonX theme's core CSS files are not minified out-of-the-box or not included in the default bundling/minification process, this is a valuable point for improvement.

Actionable Steps:
Your feedback is valuable and aligns with best practices for web performance. It is recommended to share this suggestion directly with the ABP team via their GitHub repository or support channels for consideration in future updates.

When creating a new module with the ABP CLI (abp new-module), some required NuGet packages (such as MiniExcel, Volo.Abp.BlobStoring.Database.Domain.Shared, Volo.Abp.BlobStoring.Database.Domain, Volo.Abp.BlobStoring.Database.MongoDB, etc.) may not be automatically added to the generated module projects, especially when using MongoDB as the database provider or when certain features are expected by the solution template.
This is a known limitation: the CLI-generated module template does not always include all dependencies that your main application or its modules require. You need to manually add missing NuGet packages to the relevant projects after module creation.
For example, if your application uses features like BlobStoring with MongoDB or MiniExcel, you should add the following packages manually to the corresponding projects:
Volo.Abp.BlobStoring.Database.Domain.Shared (to Domain.Shared)Volo.Abp.BlobStoring.Database.Domain (to Domain)Volo.Abp.BlobStoring.Database.MongoDB (to MongoDb and MongoDb.Tests)MiniExcel (to Application or where needed)This manual step is required to align your module with the dependencies and features used in your main solution.

The issue you described is related to the test collection naming in the generated MongoDB test files. In the generated MongoTestCollection class, the constant Name is used for the collection definition, but the test classes are likely referencing a non-existent CollectionDefinitionName constant, causing invalid references.
The correct approach is to use the defined constant Name in your test classes, like this:
[Collection(MongoTestCollection.Name)]
public class MongoDBTicketsAppServiceTests
{
// Test code here
}
If your generated test classes reference MongoTestCollection.CollectionDefinitionName, you should replace it with MongoTestCollection.Name to match the actual constant defined in the MongoTestCollection class.
This is a known pattern in ABP's MongoDB test template. You can refer to the official template for correct usage:
For more details on MongoDB test setup in ABP microservice projects, see:
To summarize, update your test classes to use MongoTestCollection.Name instead of CollectionDefinitionName to resolve the invalid reference.

In ABP's distributed event bus, the EventName attribute allows you to decouple event contracts between services by specifying a string event name, so different assemblies can use different class names as long as the EventName matches. This is supported by ABP's event bus abstraction.
However, Rebus itself (the underlying transport library) does not natively route messages based on the EventName attribute. Rebus uses the .NET type name for routing and subscription matching. This means that unless both publisher and consumer share the same .NET type (i.e., the same class full name and namespace), Rebus will not match the event, even if the EventName attribute is present.
In your scenario, since you cannot share the ETO class library and want to use only the EventName for routing, this will not work with Rebus out of the box. The ABP EventName attribute is respected by ABP's own event bus implementations (like RabbitMQ, Azure Service Bus, etc.), but not by Rebus, which relies on type-based routing.
The only way to make this work with Rebus is to ensure both publisher and consumer use the same .NET type (shared contract), or to implement a custom message mapping layer that serializes/deserializes based on EventName, which is not provided by default.
If you need to decouple contracts and use EventName-based routing, consider using another ABP-supported event bus provider (like RabbitMQ or Azure Service Bus) that supports this feature.
