To resolve the error regarding the missing 'Volo.Abp.Account.Pro.Public.Web' assembly when migrating from IdentityServer to OpenIddict in your auth-server, you need to ensure that all IdentityServer-related package references are fully replaced with their OpenIddict counterparts, as described in the official ABP migration guide.
Here are the key steps you should follow:
Update Package References:
<PackageReference Include="Volo.Abp.Account.Pro.Public.Web.IdentityServer" ... />
<PackageReference Include="Volo.Abp.AspNetCore.Authentication.JwtBearer" ... />
<PackageReference Include="Volo.Abp.Account.Pro.Public.Web.OpenIddict" Version="8.1.2" />
Update Module Dependencies:
using Volo.Abp.IdentityServer;
typeof(AbpAccountPublicWebIdentityServerModule)
using Volo.Abp.OpenIddict;
typeof(AbpAccountPublicWebOpenIddictModule)
Clean and Rebuild:
bin and obj folders in your solution.dotnet clean and dotnet build to ensure all old references are removed.Restore NuGet Packages:
dotnet restore to ensure all required packages are downloaded.nuget.config is correct and you are authenticated.Check for Transitive Dependencies:
Version Consistency:
If you follow these steps and the error persists, double-check that there are no lingering references to Volo.Abp.Account.Pro.Public.Web.IdentityServer or Volo.Abp.Account.Pro.Public.Web in any project or module dependency.
For more details, see the official migration guide:
This approach is based on the official ABP documentation and aligns with the recommended migration process.

To restore sidebar/menu click functionality after customizing the LeptonX layout in your ABP Blazor Web App, you must ensure that your custom layout component inherits from the correct base layout and is registered to replace the default one. This is required because the built-in LeptonX layouts contain the logic and event handling for menu toggling and other interactive features.
Solution:
Inherit from the Correct Base Layout:
Your custom layout Razor file must inherit from SideMenuLayout (or the appropriate LeptonX layout base class), not just LayoutComponentBase. This ensures all built-in logic and event handlers are included.
Example:
@using Volo.Abp.AspNetCore.Components.Web.LeptonXTheme.Components.ApplicationLayout
@using Volo.Abp.DependencyInjection
@inherits SideMenuLayout
@attribute [ExposeServices(typeof(SideMenuLayout))]
@attribute [Dependency(ReplaceServices = true)]
<!-- Your custom markup here -->
Register the Custom Layout:
Use the [ExposeServices] and [Dependency(ReplaceServices = true)] attributes to ensure your layout replaces the default one.
Do Not Remove Required Markup or Logic: When customizing, avoid removing essential elements or logic (such as menu toggles, event handlers, or component references) from the base layout. If you need to add or move elements, do so within the structure provided by the base class.
Example Custom Layout:
@using Volo.Abp.AspNetCore.Components.Web.LeptonXTheme.Components.ApplicationLayout
@using Volo.Abp.DependencyInjection
@inherits SideMenuLayout
@attribute [ExposeServices(typeof(SideMenuLayout))]
@attribute [Dependency(ReplaceServices = true)]
<div>
<div id="lpx-wrapper">
<MainHeader />
<div class="lpx-content-container">
<div class="lpx-content-wrapper">
<div class="lpx-content">
<ContentToolbar />
<PageAlert />
<UiPageProgress />
@Body
<DynamicLayoutComponent />
<UiMessageAlert />
<UiNotificationAlert />
</div>
</div>
<footer>
<Footer />
</footer>
</div>
<MobileNavbar />
<div class="lpx-toolbar-container">
<MainHeaderToolbar />
</div>
</div>
</div>
Check for JavaScript or CSS Issues: If you have removed or altered required scripts/styles, restore them to ensure interactive features work.
Summary:
Always inherit from the correct LeptonX layout base class and use the required attributes to replace the default layout. This preserves all built-in interactive features, including sidebar toggling.

To explicitly invalidate or revoke access tokens on logout in an ABP.IO application using OpenIddict, you need to implement token revocation logic, as JWT access tokens are typically stateless and remain valid until expiration unless actively revoked.
Here’s how you can achieve this:
Enable Token Revocation in OpenIddict:
Call the Revocation Endpoint on Logout:
/connect/revocation endpoint with the token to be revoked. This can be done from your client or server-side code.Example HTTP request:
POST /connect/revocation
Content-Type: application/x-www-form-urlencoded
token={access_token}&token_type_hint=access_token&client_id={client_id}&client_secret={client_secret}
Custom Logic with OpenIddict Events (Optional):
OpenIddictServerEvents.ProcessSignOutContext.public class SignOutEventHandler : IOpenIddictServerHandler<OpenIddictServerEvents.ProcessSignOutContext>
{
public static OpenIddictServerHandlerDescriptor Descriptor { get; }
= OpenIddictServerHandlerDescriptor.CreateBuilder<OpenIddictServerEvents.ProcessSignOutContext>()
.UseSingletonHandler<SignOutEventHandler>()
.SetOrder(100_000)
.SetType(OpenIddictServerHandlerType.Custom)
.Build();
public ValueTask HandleAsync(OpenIddictServerEvents.ProcessSignOutContext context)
{
// Custom logic here (e.g., revoke tokens)
return ValueTask.CompletedTask;
}
}
Register the handler in your module:
public override void PreConfigureServices(ServiceConfigurationContext context)
{
PreConfigure<OpenIddictServerBuilder>(serverBuilder =>
{
serverBuilder.AddEventHandler(SignOutEventHandler.Descriptor);
});
}

To add Microsoft as an external login provider in your ABP Blazor Web App (v9.2.1), you need to configure the authentication in your AuthServer project and optionally customize the UI if needed. Here’s a step-by-step guide:
Install Required NuGet Package
Microsoft.AspNetCore.Authentication.MicrosoftAccount.Configure Microsoft Authentication in AuthServer
AuthServer project, update the authentication configuration (usually in Startup.cs or Program.cs):context.Services.AddAuthentication()
.AddMicrosoftAccount(options =>
{
options.ClientId = configuration["Authentication:Microsoft:ClientId"];
options.ClientSecret = configuration["Authentication:Microsoft:ClientSecret"];
options.SaveTokens = true;
options.Scope.Add("email");
});
appsettings.json:"Authentication": {
"Microsoft": {
"ClientId": "YOUR_MICROSOFT_CLIENT_ID",
"ClientSecret": "YOUR_MICROSOFT_CLIENT_SECRET"
}
}
Configure Redirect URI in Azure Portal

To resolve the "'abp-loader-bar' is not a known element" and similar errors in your ABP Angular project, you need to ensure that the required ABP Angular modules are imported into your AppModule (or the relevant feature module). These components are provided by the ABP Angular UI libraries and must be registered in your module imports.
Follow these steps:
Make sure you have the following packages installed (use the version matching your ABP version, e.g., ~9.2.1):
yarn add @abp/ng.components @abp/ng.core @abp/ng.theme.shared
In your app.module.ts, import the necessary ABP modules:
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { CoreModule } from '@abp/ng.core';
import { ThemeSharedModule } from '@abp/ng.theme.shared';
import { AppComponent } from './app.component';
import { ComponentsModule } from '@abp/ng.components';
@NgModule({
declarations: [
AppComponent,
// ...other components
],
imports: [
BrowserModule,
CoreModule.forRoot({}),
ThemeSharedModule.forRoot(),
ComponentsModule, // <-- This is required for abp-loader-bar, abp-dynamic-layout, etc.
// ...other modules
],
providers: [],
bootstrap: [AppComponent]
})
export class AppModule { }
Do not manually declare ABP components like InternetConnectionStatusComponent in your declarations array. They are already declared in the ABP modules.
After making these changes, stop and restart your Angular development server:
yarn start
This will register the ABP components and resolve the "not a known element" errors.

As of ABP v9.2.1, ABP Suite does not provide a built-in UI option to select or target a custom DbContext when generating new entities. By default, Suite scaffolds entities into the main application DbContext.
There is no official documentation or roadmap entry confirming that multi-DbContext selection in ABP Suite is planned for a future release.
Recommended Workaround:
This approach aligns with current ABP practices for multi-DbContext solutions. For more details and examples on handling multiple DbContexts and related repository patterns, see the following validated resources:

To enable Hot Reload for Razor Pages, JavaScript, and CSS files in ABP MVC projects using the layered monolith architecture, you need to ensure that your application uses the physical files during development instead of the embedded resources. By default, ABP modules embed static and Razor files into assemblies, which prevents Hot Reload and file watchers from detecting changes.
ABP provides a solution for this scenario using the ReplaceEmbeddedByPhysical method in the Virtual File System configuration. This allows your application to use the physical files from the module project during development, so changes are immediately reflected without restarting the application.
Here’s how to configure it:
[DependsOn(typeof(MyModule))]
public class MyWebAppModule : AbpModule
{
public override void ConfigureServices(ServiceConfigurationContext context)
{
var hostingEnvironment = context.Services.GetHostingEnvironment();
if (hostingEnvironment.IsDevelopment()) // Only for development time
{
Configure<AbpVirtualFileSystemOptions>(options =>
{
options.FileSets.ReplaceEmbeddedByPhysical<MyModule>(
Path.Combine(
hostingEnvironment.ContentRootPath,
$"..{Path.DirectorySeparatorChar}MyModuleProject"
)
);
});
}
}
}
This configuration ensures that during development, changes to .cshtml, .js, and .css files in your module’s Pages folder are served directly from disk, enabling Hot Reload and immediate feedback.
No need to restart the application for every change—just refresh the browser.
This approach is already used in ABP’s application startup templates for localization files and is the recommended way to improve the development experience with embedded resources.

To resolve IDX10204 (issuer validation) and IDX10500 (signature validation) errors when using an internal MetadataAddress in Kubernetes, you must ensure that:
Here is a recommended approach for ABP microservice deployments in Kubernetes:
context.Services.AddAuthentication(JwtBearerDefaults.AuthenticationScheme)
.AddAbpJwtBearer(options =>
{
options.Authority = configuration["AuthServer:Authority"]; // Should match the issuer in the token
options.MetadataAddress = configuration["AuthServer:MetaAddress"]!.EnsureEndsWith('/') + ".well-known/openid-configuration";
options.RequireHttpsMetadata = configuration.GetValue<bool>("AuthServer:RequireHttpsMetadata");
options.Audience = configuration["AuthServer:Audience"];
// Explicitly set ValidIssuers to match the issuer in the token
options.TokenValidationParameters = new TokenValidationParameters
{
ValidIssuers = new[] { configuration["AuthServer:Authority"].EnsureEndsWith('/') }
};
});
Key Points:
AuthServer:Authority must exactly match the iss (issuer) claim in the JWT token.MetadataAddress should be the internal service address, but the issuer in the token must still match the public/external URL if that's what is issued.PreConfigure<OpenIddictServerBuilder>(serverBuilder =>
{
serverBuilder.SetIssuer("https://your-public-auth-url/");
});
/.well-known/openid-configuration and the JWKS endpoint to fetch signing keys.References:
This configuration ensures that both issuer and signing key validation work correctly in a Kubernetes environment with internal service addresses.

The issue occurs because the role names are being HTML-encoded twice or not properly decoded before rendering in the modal. This is why Turkish characters like "ç" and "ö" appear as HTML entities (e.g., ç, ö) in the modal, but display correctly elsewhere.
In ABP MVC applications, Razor automatically encodes output to prevent XSS. If your data is already HTML-encoded before being passed to the view, it will be encoded again, resulting in the display of HTML entities.
To fix this, ensure that:
@Html.Raw(roleName) only if you are 100% sure the data is safe and not user-supplied, otherwise just use @roleName (the default).If you are using a custom modal or JavaScript to render the role names, make sure you are not encoding the names twice (e.g., once on the server and once on the client).
Example Razor usage:
@* Correct: roleName is plain text, Razor encodes it automatically *@
<span>@roleName</span>
@* If you must decode HTML entities (not recommended for user input): *@
<span>@Html.Raw(roleName)</span>
Review your backend and frontend code to ensure you are not manually encoding the role names before passing them to the view or JavaScript.
For more on Razor Tag Helpers and encoding, see:
Summary:
Store and handle role names as plain Unicode strings, let Razor handle encoding, and avoid double-encoding in your backend or JavaScript. Use @roleName in Razor unless you have a specific reason to use @Html.Raw.
