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:

1. In your web project’s module (e.g., MyWebAppModule), update the ConfigureServices method:

[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"
                    )
                );
            });
        }
    }
}

• Replace MyModule and MyModuleProject with your actual module class and project folder name.

2. 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.

3. 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:

1. The issuer in your tokens matches the expected issuer in your Host API configuration.
2. The Host API can access the Auth Server's OpenID configuration and signing keys using the internal address.
3. The ValidIssuers and Authority are set correctly, and the keys are available for signature validation.

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:

• The value of AuthServer:Authority must exactly match the iss (issuer) claim in the JWT token.
• The 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.
• If your Auth Server is behind a reverse proxy or ingress, ensure the issuer in the token is set correctly. You may need to override the issuer in your Auth Server configuration using:

  PreConfigure<OpenIddictServerBuilder>(serverBuilder =>
  {
      serverBuilder.SetIssuer("https://your-public-auth-url/");
  });
  

• The Host API must be able to reach the internal /.well-known/openid-configuration and the JWKS endpoint to fetch signing keys.

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:

  1. Role names are stored and retrieved as plain Unicode strings (not HTML-encoded) in your database and backend.
  2. In your Razor view, use @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:

  • https://abp.io/docs/en/abp/latest/UI/AspNetCore/Tag-Helpers

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.

• The error InvalidOperationException: sub claim is missing after upgrading to ABP 9.0 (while still using IdentityServer4) is due to a missing sub (subject) claim in the authentication response. IdentityServer4 requires the sub claim to identify the user.

• In ABP 9.0, there have been significant changes and migration steps, especially regarding authentication and claims handling. If you have not migrated to OpenIddict and are still using IdentityServer4, you must ensure that your authentication pipeline and claims transformation logic are compatible with the new ABP version.

• Specifically, you should:

  1. Check your user claims generation logic and ensure the sub claim is present and correctly mapped for the authenticated user.
  2. Review any custom profile service or claims transformation code to ensure it is not omitting the sub claim.
  3. If you are using custom login or external authentication providers, ensure they provide the sub claim in the identity token.

• For more details and migration steps, see:

  • ABP Version 9.0 Migration Guide
  • ABP IdentityServer Module
  • ABP OpenIddict Module

These resources provide guidance on handling authentication and claims in ABP 9.0 and can help you resolve the missing sub claim issue.

To properly integrate your Blazor Server module (GravityPlatform.AccountManagement) into your Blazor Web App (app-nolayers template), you need to ensure the following dependencies and references are set up:

1. Add Project References:

   • GravityPlatform.AccountManagement should be referenced by GravityPlatform.Host.
   • GravityPlatform.AccountManagement.Contracts should be referenced by GravityPlatform.Contracts.
   • GravityPlatform.AccountManagement.Blazor should be referenced by GravityPlatform.Web (or the main Blazor project).

2. Module Dependencies:

   • In your main Blazor module class (e.g., GravityPlatformWebModule or similar), add a DependsOn attribute for GravityPlatform.AccountManagementBlazorModule:

     [DependsOn(
         typeof(GravityPlatformAccountManagementBlazorModule)
     )]
     public class GravityPlatformWebModule : AbpModule
     {
         // ...
     }
     

   • If you have a UI module (GravityPlatform.AccountManagement.UI), and it contains UI components, also add it as a dependency in the same way.

3. Menu Contributor:

   • Ensure your module defines a MenuContributor and that it is registered. This is required for menu items to appear. If your module does not add menu items, nothing will show up by default.

4. Bundling:

   • If your module has JS/CSS assets, ensure you run the bundling process or use the new Global Assets system if on ABP 9+.

5. Migration and Permissions:

   • Make sure you have run the database migrations for your module.
   • Ensure the user/role you are testing with has the necessary permissions to see the menu and access the module.

6. UI Registration:

   • GravityPlatform.AccountManagement.Blazor must be referenced by your main Blazor project and included as a dependency in the main module.

Example summary:

• Reference GravityPlatform.AccountManagement.Blazor in your main Blazor project.
• Add DependsOn(typeof(GravityPlatformAccountManagementBlazorModule)) to your main module.
• Ensure menu contributor is present and registered.
• Run migrations and check permissions.

If you follow these steps, your module's menu and pages should appear in your Blazor Web App.

In a Blazor WebApp "No Layer" (monolithic) ABP solution, when adding a new module via ABP Suite, you are correct in your assumptions:

• If you select the "Blazor Server" option for the module, it will integrate directly with your application using dependency injection (DI). This is the most compatible and straightforward choice for a Blazor WebApp monolith, as it allows you to use services and components without needing to expose HTTP APIs.
• If you select the "WebAssembly" option, the module is designed for a client-side Blazor WebAssembly scenario. In this case, you would typically need to expose HTTP API controllers for the client to communicate with the backend, which is not necessary in a pure Blazor Server or Blazor WebApp (monolithic) setup.

For a Blazor WebApp "No Layer" solution, choose "Blazor Server" when adding modules for the most seamless integration.

Regarding documentation and enhancements for Blazor WebApp, ABP is actively evolving its documentation and features. The most up-to-date and official starting point is the "Get Started" section:

• Get Started with ABP

This page is regularly updated as new features and documentation become available.

If you need to add modules or extend your application, follow the standard ABP modularity approach, but always prefer the "Blazor Server" option for modules in a monolithic Blazor WebApp.

1. The "Could not find localization source" errors (AMS, AbpUi, AbpIdentity) indicate that the required localization resources are missing or not properly registered after your upgrade. This is a common issue when upgrading major ABP versions, especially from v4.x to v9.x, due to changes in the localization system and resource file structure.

   • Ensure that all required localization resource files (e.g., AMS.xml, AbpUi.xml, AbpIdentity.xml) exist in the correct locations (typically under Localization folders in each module or project).
   • Verify that your module classes are properly registering their localization resources in the ConfigureServices method using the new ABP v9 syntax.
   • Check the ABP 9.1 migration guide for any breaking changes related to localization and resource registration.

2. The Uncaught TypeError: id.replace is not a function error is likely caused by a JavaScript code expecting a string id, but receiving an object or another type. This can happen if the structure of data returned from the backend has changed after the upgrade, or if a localization key is missing and returns an object instead of a string.

   • Review the code at the specified line in Index.js and ensure that the id variable is always a string before calling .replace.
   • Check if any localization or menu item keys are missing or misconfigured, as this can cause such issues in ABP UI.

3. The UI issues (e.g., "PagerShowMenuEntries" and "ProcessingWithThreeDot" showing as raw keys) are also related to missing or unregistered localization resources.

Recommended Steps:

• Review and update your localization resource files and registration according to the ABP 9.1 migration guide.
• Rebuild your solution and clear browser/server caches.
• If you have custom modules (like AMS), ensure their localization is registered as described in the migration guide.

• If you are not receiving the registration confirmation email from ABP.io, please check the following:
  1. Verify the email is not in your spam or junk folder.
  2. Ensure that your email server is not blocking emails from abp.io.
  3. If you are using a corporate email (like tasconnect.com), your IT department may have filters or firewalls that block automated emails. Ask them to whitelist abp.io or check their email logs.
  4. Try registering with a different email provider (such as Gmail or Outlook) to see if the issue is specific to your domain.

This error, "Validating access_token failed, wrong state/nonce," typically occurs in ABP Angular applications when multiple tabs are open and the session expires or the access_token is deleted. The root cause is that the OAuth2/OIDC state and nonce values are stored in browser storage (localStorage/sessionStorage), and having multiple tabs can cause these values to become out of sync, especially after a session timeout or manual token removal. Chrome and Edge are more aggressive in synchronizing storage across tabs, which is why the issue is more visible there compared to Firefox.

Solution / Workaround

1. Single Tab Recommendation:
   This is a known limitation of SPA OAuth2/OIDC flows. Advise users to avoid logging in again in multiple tabs simultaneously after session expiration.

2. Custom State/Nonce Storage:
   Consider customizing the storage mechanism for state/nonce to be tab-specific (e.g., using sessionStorage instead of localStorage, or using a unique key per tab).

3. Session Management Module:
   ABP Commercial provides a Session Management feature to help prevent concurrent login/session issues. See the documentation for more details.

4. Logout Handling:
   Ensure that your logout implementation clears all relevant tokens and state in all tabs, possibly by broadcasting a logout event using localStorage or another mechanism.

5. Reference Issues:
   This is a common scenario in OAuth2/OIDC SPAs and is discussed in the community and GitHub issues. See the following for more details and possible workarounds:

ABP Framework does not provide a built-in LastLogin field in the default Users table (AbpUsers). However, ABP does offer a way to track user login events through the Security Log feature, which records login and logout activities.

Recommended Approach

1. Use Security Logs to Track Logins

   • ABP automatically logs user login events in the Security Log. You can query the security logs to get the last login time for a user.
   • The relevant table is usually AbpSecurityLogs (or similar, depending on your version).

2. Custom LastLogin Property (Recommended for Direct Access)

   • If you want a direct LastLogin field on the user entity, you can extend the IdentityUser entity to add a custom property.
   • Update this property whenever a user successfully logs in (e.g., in a custom login event handler or by overriding the login logic).

   Example:

   // 1. Add property to user entity (see ABP docs for entity extension)
   ObjectExtensionManager.Instance
       .MapEfCoreProperty<IdentityUser, DateTime?>("LastLoginTime");
   
   // 2. Update LastLoginTime after successful login
   user.SetProperty("LastLoginTime", DateTime.UtcNow);
   

   • Don't forget to add a migration and update the database.

3. SignalR/Active User Tracking (Optional)

   • For real-time tracking of currently logged-in users, you can use SignalR and manage a list of active users in memory or cache, as shown in the ABP support example.

Summary

• There is no built-in LastLogin field, but you can use Security Logs or extend the user entity to add and maintain this value yourself.
