• What you’re seeing is consistent with client-side permission caching in ABP Angular / application-configuration usage, not with AbpPermissionGrants being “wrong”.
• In ABP, changing role/user permissions is effective on the server immediately, but the UI may continue to use the previous grantedPolicies until the client refreshes/reloads its cached application configuration.

Do this to fix your scenario (RBAC not reflected after you remove permissions):

1. Force the Angular client to re-load application configuration after login/logout and after permission changes

   • Ensure you are not keeping the old ApplicationConfigurationDto in memory across sessions (SPA can do this).
   • After logout, do a hard reload (or clear the cached config state your app keeps).
   • After changing permissions from the UI, also reload the page (or explicitly re-fetch /api/abp/application-configuration) for the affected user to refresh grantedPolicies.

2. Verify you are not accidentally checking an empty/incorrect permission key in Angular

   • If your permission name expression becomes ''/null due to a bug, many UI checks will behave unexpectedly and may look like “everything is granted”.
   • Confirm the exact permission string you use in *abpPermission, PermissionService.getGrantedPolicy(...), etc.

3. Double-check tenant context when reading grants

   • AbpPermissionGrants is tenant-scoped. If you check grants with the wrong TenantId or wrong provider key/name, you can think it “doesn’t exist” while it actually exists for another tenant/provider.

4. Confirm it’s not granted via another provider

   • Even if you removed a permission from a user, it can still be granted via a role (or another provider). In the Permission Management UI, the “(R)” indicator shows role-originated grants.

If you implement #1 (refresh/re-fetch application configuration) your “removed permissions still come back in open configuration response” symptom should stop, because the frontend will stop using the stale grantedPolicies.

• With ABP’s built-in Azure Service Bus distributed event bus provider, a single host application can be configured with only one TopicName and one SubscriberName via Azure:EventBus (that config maps to one topic + one subscription for that app). There is no supported appsettings.json format to declare multiple topics/subscriptions for the same host using the default provider.

• If you must use one host app and still consume from 3 topic/subscription pairs, you have only these viable options:

1. Recommended ABP way: use 1 topic, 1 subscription, and let ABP route by event type

   • Put all events on one Azure Service Bus topic (e.g. MyApp).
   • Keep one subscription for the host (e.g. MyHost).
   • ABP already dispatches incoming messages to handlers based on event name/type; you don’t need separate topics per event group.
   • Config stays exactly like you already have (single topic/subscriber).

2. If you strictly need 3 different topics: do it outside ABP EventBus

   • Keep ABP’s distributed event bus configured for one topic/subscription (or disable it if you won’t use it).
   • Then, for the other topics/subscriptions, use the raw Azure SDK (Azure.Messaging.ServiceBus) and create your own ServiceBusProcessor instances (one per topic/subscription) inside your host app.
   • This is not configurable “in the existing ABP Azure:EventBus format”; it’s custom code.

Because option (2) requires custom code and ABP has no official “multiple topics per app” configuration for the Azure EventBus provider, the direct answer to “how to do it in the same host app via appsettings” is: you can’t with the default ABP Azure EventBus configuration.

• In ABP’s Azure Service Bus distributed event bus integration, the Azure:EventBus section represents a single topic + a single subscription name per application:

  • TopicName = the topic ABP publishes to / listens from
  • SubscriberName = the subscription name created/used under that topic for this application

• Because of that, you can’t configure 3 topics + 3 subscriptions in the same Azure:EventBus section in appsettings.json in the “existing format”. ABP reads one TopicName and one SubscriberName.

• What you should do instead:

  1. Pick one topic for your whole solution (recommended), e.g. MyApp.
  2. Configure one SubscriberName per microservice/app (each consumer app uses a different subscription under the same topic).
  3. If you truly must use multiple topics, you need separate applications/hosts with different Azure:EventBus configs (one per topic) or implement a custom event bus provider/routing (not supported via appsettings in the default provider).

Example (recommended): single topic, 3 subscriptions (3 apps)

• appsettings.json for ServiceA:

{
  "Azure": {
    "ServiceBus": {
      "Connections": {
        "Default": {
          "ConnectionString": "Endpoint=sb://sb-my-app.servicebus.windows.net/;SharedAccessKeyName=...;SharedAccessKey=..."
        }
      }
    },
    "EventBus": {
      "ConnectionName": "Default",
      "TopicName": "MyApp",
      "SubscriberName": "ServiceA"
    }
  }
}

• appsettings.json for ServiceB:

{
  "Azure": {
    "ServiceBus": {
      "Connections": {
        "Default": {
          "ConnectionString": "Endpoint=sb://sb-my-app.servicebus.windows.net/;SharedAccessKeyName=...;SharedAccessKey=..."
        }
      }
    },
    "EventBus": {
      "ConnectionName": "Default",
      "TopicName": "MyApp",
      "SubscriberName": "ServiceB"
    }
  }
}

• appsettings.json for ServiceC:

{
  "Azure": {
    "ServiceBus": {
      "Connections": {
        "Default": {
          "ConnectionString": "Endpoint=sb://sb-my-app.servicebus.windows.net/;SharedAccessKeyName=...;SharedAccessKey=..."
        }
      }
    },
    "EventBus": {
      "ConnectionName": "Default",
      "TopicName": "MyApp",
      "SubscriberName": "ServiceC"
    }
  }
}

If you put EntityPath=... in the connection string: for topics/subscriptions, ABP already uses TopicName, so keep the connection string at the namespace level (no EntityPath) unless you have a specific reason.

• @volo/abp.aspnetcore.mvc.ui.theme.leptonx (MVC UI) does not ship Dropzone. In current LeptonX MVC packages, the file-upload component/library used by the theme is Uppy, so seeing uppy installed is expected behavior.
• Therefore, you won’t find Dropzone files under wwwroot/libs/... (or in LeptonX’s bundled assets) unless your solution explicitly adds Dropzone.

If you specifically need Dropzone in an ABP MVC app:

1. Install it yourself (npm/yarn) and expose it to wwwroot (e.g., via your frontend build, LibMan, or by copying from node_modules into wwwroot/libs).
2. Include its CSS/JS in your layout (or via ABP bundling) and use it in your page.

• What you are seeing is expected with ABP’s default background job executor in a scaled-out (multiple instance) environment: each instance runs its own background job worker, so if the storage/provider doesn’t guarantee distributed “pick and lock”, you can end up with duplicate executions.

• Best practice options (recommended order):

  1. Use a real distributed background job provider (Hangfire)

     • Configure ABP Background Jobs to use Hangfire, so job acquisition/execution is coordinated across instances (Hangfire uses distributed locks in its storage).
     • This is the recommended approach when you want multiple servers/instances processing jobs reliably and you want retries, dashboards, etc.
     • ABP already has integration so your app code that enqueues jobs doesn’t need to change.

  2. Run background job execution in a separate “job executor” application (single instance)

     • Keep your web app scaled out, but disable job execution in the web app(s), and run a dedicated console/worker app that executes jobs (can be scaled independently later with a proper provider).
     • In ABP, you can disable job execution in the web application via:

Configure<AbpBackgroundJobOptions>(options =>
       {
           options.IsJobExecutionEnabled = false;
       });

 - Then create a separate console app that references your job types and runs the background job module/provider.

3. Add idempotency at the business level (still recommended even with 1/2)
   • For “send email” jobs, store a unique business key (e.g., EmailNotificationId / CorrelationId) and enforce “send only once” in your own tables (unique index + “already sent” check).
   • This protects you not only from scale-out races, but also from retries, transient failures, and user double-clicks.

• Practical guidance for your exact scenario (Azure App Service, 2 instances):
  • If you want to keep background jobs inside the same web host(s), switch to Hangfire integration (Option 1).
  • If you want the simplest “guarantee single execution” without bringing a distributed job system immediately, implement Option 2 (single executor) and later you can still move that executor to Hangfire if you need throughput.

• In ABP, /api/abp/application-configuration returns auth.grantedPolicies for the current user. A permission can be true there even if there is no row in AbpPermissionGrants.

  • Because the permission system is not “DB row = granted”. The DB table stores overrides (grant/prohibit) for a provider (Role/User/Client). If a permission is granted by some other mechanism, you may not see a direct row for the specific permission/provider you are checking.
  • Common reasons a permission shows as true without a matching row:
    1. Granted by role (or another provider): the grant may exist for the role (or another provider), not for the user. So you won’t find a row when filtering by the user’s provider key.
    2. Default-granted permissions: some permissions are defined to be granted by default (or effectively always granted for certain users like host admin depending on module/permission configuration). In such cases, ABP can return true without needing a DB record.
    3. You are looking at the wrong tenant/provider key: AbpPermissionGrants is tenant-scoped. If you check the table without matching TenantId (and correct ProviderName/ProviderKey), you can miss the record that actually caused the grant.
    4. Stale client-side application configuration: Angular reads permissions from the application-configuration response and caches it in the client. If permissions changed, the UI can keep showing old values until a full refresh.

• Fix it in a definitive way (server + Angular):

  1. Confirm what provider grants it
     • Use the Permission Management UI to inspect the permission for the user/role and see whether it is granted via role or another provider.
     • In code, prefer PermissionAppService.GetAsync(providerName, providerKey) (Permission Management Module) which returns details including “granted providers” (useful for diagnosing why it’s true).
  2. Verify the correct tenant
     • When you query AbpPermissionGrants, filter by the correct TenantId (and correct ProviderName/ProviderKey).
  3. If your intention is “not granted unless explicitly granted”
     • Ensure the permission is not configured as granted by default in its definition.
     • Explicitly prohibit it for the relevant provider (role/user) so ABP persists a IsGranted = false row (a prohibition). That guarantees the permission resolves to false even if it might otherwise be granted.
  4. Refresh Angular’s permission map
     • After changing permission grants, do a full page reload so Angular re-fetches /api/abp/application-configuration.
     • If you update permissions from within the app, reset the current application configuration cache on the client side (ABP provides mechanisms for cache reset in some UIs; otherwise reload is the simplest).

• Angular button show/hide best practice:

  • Use ABP Angular’s PermissionService.getGrantedPolicy(...) (or getGrantedPolicy$) and ensure you are checking the exact permission name.
  • Be careful: an empty string permission key returns true in ABP Angular permission selectors, which can make it look like “everything is true” if the key you pass is accidentally empty.

• In a separate Public Web (MVC/Razor) + separate AuthServer (OpenIddict) setup, the Public Web must be an OpenID Connect client and use its own local cookie for the signed-in session. If the OIDC client/cookie setup is missing or misconfigured, the login UI can appear to work (credentials accepted on AuthServer) but no auth cookie is created in the Public Web, so ICurrentUser.IsAuthenticated stays false.

• Do this in Public Web (its *.Web project/module), ensuring:

  1. Cookie is the default scheme (this is what populates HttpContext.User/ICurrentUser in the Public Web app).
  2. OpenIdConnect is the challenge scheme (redirects to AuthServer).
  3. Redirect URI matches the Public Web host (e.g. https://localhost:44387/signin-oidc) and is registered in OpenIddict client.
  4. (Common pitfall) Disable calling userinfo unless you really need it (otherwise you can get “login succeeds but no user is established” symptoms depending on token/claims settings).

Public Web – authentication configuration (example)

Put/adjust in your Public Web module (e.g. PublicWebModule / YourProjectWebModule) ConfigureServices:

using Microsoft.AspNetCore.Authentication.Cookies;
using Microsoft.AspNetCore.Authentication.OpenIdConnect;
using Microsoft.IdentityModel.Protocols.OpenIdConnect;

private void ConfigureAuthentication(ServiceConfigurationContext context, IConfiguration configuration)
{
    context.Services.AddAuthentication(options =>
        {
            options.DefaultScheme = CookieAuthenticationDefaults.AuthenticationScheme;
            options.DefaultChallengeScheme = OpenIdConnectDefaults.AuthenticationScheme;
        })
        .AddCookie(CookieAuthenticationDefaults.AuthenticationScheme, options =>
        {
            // Optional but recommended in multi-app scenarios:
            options.Cookie.Name = ".YourCompany.PublicWeb.Auth";
        })
        .AddOpenIdConnect(OpenIdConnectDefaults.AuthenticationScheme, options =>
        {
            options.Authority = configuration["AuthServer:Authority"]; // https://localhost:44349
            options.RequireHttpsMetadata = Convert.ToBoolean(configuration["AuthServer:RequireHttpsMetadata"]);

            options.ClientId = configuration["AuthServer:ClientId"];         // the PublicWeb client id in OpenIddict
            options.ClientSecret = configuration["AuthServer:ClientSecret"]; // if applicable
            options.ResponseType = OpenIdConnectResponseType.Code;
            options.UsePkce = true;

            options.SaveTokens = true;

            // IMPORTANT (often fixes “login ok but not authenticated” issues due to userinfo problems)
            options.GetClaimsFromUserInfoEndpoint = false;

            options.Scope.Clear();
            options.Scope.Add("openid");
            options.Scope.Add("profile");
            options.Scope.Add("email");
            options.Scope.Add("roles");
        });
}

AuthServer – OpenIddict client must match Public Web URLs

In the AuthServer’s OpenIddict client registration (seed/config), ensure the Public Web client has:

• redirect_uri: https://localhost:44387/signin-oidc
• post_logout_redirect_uri: https://localhost:44387/signout-callback-oidc
• Allowed grant type: authorization_code
• (If using PKCE) PKCE enabled/compatible
• Scopes include at least openid profile email roles (+ any API scopes you need)

Why ICurrentUser is empty

ICurrentUser is populated from the current HTTP request user principal. In an MVC app that comes from the local authentication cookie. If the Public Web app doesn’t issue/receive its own cookie after the OIDC callback, HttpContext.User stays anonymous → ICurrentUser stays empty.

Recommended way to “share authentication” between Admin/AuthServer and Public Web

• Don’t try to share the same cookie across apps/domains/ports.
• Use centralized AuthServer (OpenIddict) + each UI (Admin and Public) is a separate OIDC client with its own cookie.
• You’ll still get SSO-like behavior because the AuthServer session persists; subsequent logins from the other app typically won’t prompt credentials.

• This symptom (Create/Edit User/Role “never completes” and then times out) is almost always a SQL Server execution timeout caused by blocking/locked rows on ABP Identity tables (AbpUsers, AbpRoles, AbpUserRoles) rather than an ABP “CreateAsync bug”.
• The exact pattern is: the request reaches Volo.Abp.Identity.IdentityUserController.CreateAsync, then EF Core executes a batch that updates role concurrency stamps + inserts into AbpUserRoles, but SQL Server can’t finish within the default 30s (because it’s blocked or the DB is overloaded). In Azure this can happen with DTU/CPU pressure, long-running transactions, or stuck pods/instances holding locks.

1) Find and remove the blocker (real fix)

While reproducing the issue (try creating a user), run this on the same SQL database used by the Identity service:

-- Who is blocked / blocking right now?
SELECT
    r.session_id,
    r.status,
    r.command,
    r.blocking_session_id,
    r.wait_type,
    r.wait_time,
    r.wait_resource,
    t.text AS sql_text
FROM sys.dm_exec_requests r
OUTER APPLY sys.dm_exec_sql_text(r.sql_handle) t
WHERE r.session_id > 50;

What to look for:

• blocking_session_id <> 0
• wait_type like LCK_M_*
• statements touching AbpUsers / AbpRoles / AbpUserRoles

If you see a suspended session coming from one of your app instances/pods (common in tiered + distributed setups), the practical fix is:

• restart the offending API/AuthServer pod/app instance (this releases locks immediately), and/or
• fix whatever background job / request is holding a long transaction open.

2) Immediate mitigation: increase EF Core command timeout (workaround)

This doesn’t fix blocking, but it prevents failing at exactly 30 seconds while you diagnose:

In the module where you configure EF Core (your Identity/HttpApiHost EF Core module), configure SQL Server command timeout:

using Microsoft.EntityFrameworkCore;
using Volo.Abp.EntityFrameworkCore;

public override void ConfigureServices(ServiceConfigurationContext context)
{
    Configure<AbpDbContextOptions>(options =>
    {
        options.UseSqlServer(sqlOptions =>
        {
            sqlOptions.CommandTimeout(120); // seconds
        });
    });
}

3) Production checklist (to prevent recurrence)

• Ensure no long-running Unit of Work is updating many users/roles in one transaction.
• Ensure the Azure SQL tier has enough resources (DTU/vCore). Blocking becomes much more visible under load.
• If you’re running multiple replicas, verify you don’t have a stuck instance holding transactions (a restart fixing it is a strong indicator).

It’s not expected for an Angular UI solution to be created without an angular folder.

In ABP solution templates, when you select UI: Angular, the generated solution should include an angular directory at the root (this is where the Angular client-side app lives). If it’s missing after creating the solution in ABP Studio, it usually means the UI part was not generated/downloaded successfully during creation (e.g., a failed/blocked “install/generate frontend” step).

What you can do (safe steps that don’t change your backend structure):

1. Create the solution again with the same options, and ensure ABP Studio completes all steps (especially the frontend generation / npm-yarn install steps if you enabled them).
2. If ABP Studio has an option like “Run Install Libs” / “Install packages”, enable it and re-create (or re-run the related step if the UI shows it).
3. As a workaround, you can generate the same solution using the CLI (abp new ... -u angular) and compare outputs; the Angular folder should be there in the CLI-generated structure too.

If ABP Studio consistently creates the backend but skips Angular generation, it’s a Studio-side issue/regression after the upgrade.
