Answer
  • Configure<AbpClockOptions>(options => options.Kind = DateTimeKind.Utc); only enables ABP’s UTC clock / multi-timezone behavior. It does not automatically add a “TimeZone dropdown” to your React UI.
  • After enabling UTC clock:
    • ABP will normalize DateTime values to UTC when writing/returning (you’ll typically see ISO-8601 with Z, e.g. 2025-03-01T10:30:00Z).
    • ABP can convert between UTC and the current user’s time zone via IClock.ConvertToUserTime(...) / IClock.ConvertToUtc(...).

What determines “user time zone”?

ABP uses the Abp.Timing.TimeZone setting. If it’s not set, ABP can detect the browser time zone during initialization and store it in the request (cookie/header) and then use it for conversions (middleware-based behavior is described in the multi-timezone article).

So:

  • If you don’t configure a per-user time zone in settings, the app can still work based on browser time zone detection.
  • A “timezone dropdown” exists only if your UI implements/exposes that setting (not guaranteed in every UI/template out-of-the-box).

How to achieve “store UTC, show in user/browser time zone” in practice

  1. Backend: keep UTC
Configure<AbpClockOptions>(options =>
{
    options.Kind = DateTimeKind.Utc;
});
  1. Display in UI (React/JS): convert UTC -> local/user
  • When you receive 2025-03-01T10:30:00Z, display it by converting to the user’s locale/time zone (ABP JS APIs exist for this in supported UIs; conceptually the article shows using abp.clock.normalizeToLocaleString(...) for display).
  1. When sending a date picked in UI: convert local -> UTC before POST
  • If the user selects 2025-03-01 10:30 in their local time zone, you must convert to a UTC ISO string before sending, otherwise the backend will store “as-is” and you’ll see offsets/issues. The article demonstrates doing this using ABP JS helpers (e.g., abp.clock.normalizeToString(...) / datepicker helpers).

  • With ABP Volo.Abp.AdminConsole 10.4.x–10.6.x (including 10.6.0), the Admin Console React UI renders “Back to the application” as a client-side router link to /. Since the Admin Console router is mounted with basepath = /admin-console, that navigation resolves to /admin-console, not to your separate React SPA. In other words: in these versions there is no built-in “return URL” concept for that link in the shipped Admin Console bundle.

  • The Admin Console runtime configuration endpoint (/admin-console/api/config) (as documented) exposes Admin Console options like enabling/disabling, redirecting / to /admin-console, authority/client id/scope, theme, localization, etc., but it does not document (or provide) an application.returnUrl that the built-in UI could use for this link. So there is nothing you can configure today (in 10.6.0) to make that link point back to your separate React app.

  • Practical, supportable workaround (backend-side) that avoids patching minified JS:

    1. Disable the “redirect backend root to admin-console” behavior so that / is not the Admin Console entry point:
      • Set AdminConsole:RedirectRootToAdminConsole to false (or the equivalent AbpAdminConsoleOptions.RedirectRootToAdminConsole = false).
    2. Then ensure your backend root / (or a dedicated endpoint like /return-to-app) performs an HTTP redirect to your SPA root (e.g. /app) — using your own controller/middleware.
      • This way, even if the Admin Console navigates to /admin-console (or to / under certain conditions), you can control what / does and make it “go back to the application”.
  • If you want the behavior you described (“application.returnUrl from runtime config + render as <a href=...>”), that matches the documented pattern in the “Non React UI Integration” document, but Admin Console does not currently implement that pattern in the shipped package versions you tested.

  • What you’re seeing is consistent with the Admin Console React SPA being built for a fixed /admin-console base path. Under UsePathBase("/sub/backend") (or IIS virtual application), the server can still serve /sub/backend/admin-console/*, but the client-side router (TanStack Router) and several root-absolute asset/API URLs inside the compiled bundle still assume the app is mounted at the site root, so the SPA matches no routes and shows its own “404 Page not found”.

  • In ABP 10.6, the Admin Console hosting model is documented as being served under a fixed path:

    • UI: /admin-console/*
    • API: /admin-console/api/* This aligns with your observation that the compiled SPA hardcodes /admin-console and does not automatically incorporate Request.PathBase.
  • Practical resolution (supported approach today): run Admin Console at a host root OR provide it an origin that has no PathBase.

    1. Deploy the host application at the domain root (no PathBase) or
    2. If your organization constraint is “no new domain”, use an existing shared domain but map a separate IIS site/application (or reverse-proxy rule) so that the Admin Console is reachable at a root-level path on some origin (even if it’s internal), e.g.:
      • https://example.org/admin-console (root app) instead of https://example.org/sub/backend/admin-console
    3. If you must keep the main host under /sub/backend, then the only reliable workaround on 10.6.x is essentially what you already implemented: rewrite the served HTML/JS/CSS/config responses to inject the effective base path (because the SPA is shipped as embedded static resources and is not path-base aware).
  • There is no consumer-side configuration in AbpAdminConsoleOptions that can fix the SPA router base/chunk base/font URLs when the bundle itself is compiled with root-absolute /admin-console... paths. Options like Authority / ThemeOverrideCssPath can only patch a subset of the problems you listed.

  • If you want this fixed upstream, the core requirement is: Admin Console SPA build needs to derive its base at runtime (e.g., from document.baseURI / injected <base href> / a config endpoint) and avoid root-absolute URLs in emitted CSS and dynamic imports. As you noted, simply serving it under a PathBase is not enough if the bundle is compiled with a fixed base.

  • The stack trace you shared is not a NuGet/package-version problem anymore. It’s a runtime connectivity problem:
    • RabbitMQ: No connection could be made because the target machine actively refused it (127.0.0.1:5672)
    • Redis: UnableToConnect on 127.0.0.1:6379

Updating packages may have fixed your build, but it won’t fix these two services being unreachable.

1) RabbitMQ: “service running” but port 5672 refused

This error means nothing is accepting TCP connections on 127.0.0.1:5672. Even if the Windows service shows “Running”, the broker may not actually be listening (or it’s bound differently / blocked).

Fix options (pick one):

  • Ensure RabbitMQ is listening on 5672 and reachable on localhost.
  • Or change ElsaDemoApp.Server RabbitMQ configuration to match the actual host/port you have.

In ElsaDemoApp.Server appsettings (the one actually used at runtime), verify the RabbitMQ endpoint is correct, e.g.:

"RabbitMQ": {
  "Connections": {
    "Default": {
      "HostName": "localhost",
      "Port": "5672"
    }
  }
}

2) Redis is also required by this demo (and it’s not running)

Your log shows ABP is using Redis for distributed cache at 127.0.0.1:6379, and that connection is failing. You must either:

A) Start Redis on localhost:6379 (recommended for the demo), or
B) Change the Redis connection string to wherever your Redis actually is, or
C) Disable Redis for local run (only if the sample supports that in its configuration; otherwise you’ll keep hitting caching initialization failures).

Given your exception comes from ABP’s feature/permission static savers hitting distributed cache, running Redis is the simplest path.

3) About the csproj you attached

I can’t access /QA/Files/Download/... from here, so I can’t verify the exact package versions you updated. But again: your current crash is clearly from RabbitMQ + Redis connectivity, not package resolution.

If you want the quickest “known-good” environment to run ElsaDemoApp:

  • Run RabbitMQ and Redis locally (or via Docker), and keep the demo’s endpoints pointing to localhost:5672 and localhost:6379.

  • Your log shows two separate connectivity problems while starting ElsaDemoApp.Server:
    1. RabbitMQ connection refused: 127.0.0.1:5672
    2. Redis connection timeout/unreachable: 127.0.0.1:6379

1) Fix RabbitMQ (5672)

  1. Ensure the RabbitMQ broker is actually listening on port 5672 (the Windows service being “Running” doesn’t always guarantee the listener is reachable).
  2. Ensure your ElsaDemoApp.Server configuration points to the correct host/port and credentials.

In ElsaDemoApp.Server/appsettings.json (or the environment-specific variant), ensure you have a correct RabbitMQ section similar to:

"RabbitMQ": {
  "Connections": {
    "Default": {
      "HostName": "localhost",
      "Port": "5672"
    }
  }
}

If your RabbitMQ uses non-default credentials, also set UserName / Password (ABP reads RabbitMQ connection settings from configuration).

2) Fix Redis (6379) OR disable Redis for local run

Your startup fails later because ABP is trying to use Redis distributed cache at 127.0.0.1:6379:

  • If you want to use Redis: install/run Redis and make sure it listens on 6379.
  • If you don’t want Redis for local demo: remove/disable Redis caching configuration so the app falls back to in-memory distributed cache (common for single-node local dev).

If Redis is enabled in config, verify something like this in appsettings.json:

"Redis": {
  "IsEnabled": "true",
  "Configuration": "127.0.0.1:6379"
}

Make it consistent with your actual Redis endpoint. If you don’t have Redis, set IsEnabled to false or remove the Redis configuration section used by the solution.

3) Important note about “updating all NuGet packages”

For samples like ElsaDemoApp, upgrading packages arbitrarily can introduce version mismatches. Prefer keeping package versions aligned with the sample’s original ABP version (you mentioned ABP 10.6.0). If you already upgraded, revert to the original versions shipped with the sample (or align all ABP packages to the same version).

  • For Angular + LeptonX, the officially supported mechanism to swap LeptonX layout pieces (toolbar area, nav, breadcrumb, footer, etc.) is ABP Angular Component Replacement via ReplaceableComponentsService + LeptonX component keys (eThemeLeptonXComponents.*). You register your replacement at app startup, and LeptonX renders your component in that slot.
// e.g. app.component.ts (or an app initializer)
  import { ReplaceableComponentsService } from '@abp/ng.core';
  import { eThemeLeptonXComponents } from '@volosoft/abp.ng.theme.lepton-x'; // LeptonX (commercial)
  import { MyToolbarContainerComponent } from './my-toolbar-container.component';

  constructor(replaceable: ReplaceableComponentsService) {
    replaceable.add({
      key: eThemeLeptonXComponents.Toolbar,   // slot key
      component: MyToolbarContainerComponent, // your implementation
    });
  }
  • For replacing the overall application layout (what you described as “currently rendered via abp-dynamic-layout”): ABP’s supported way is to replace the layout component (still using component replacement). Practically, your root template can stay as <abp-dynamic-layout />, while you replace the layout slot used by LeptonX to render the shell. (This keeps ABP’s route integration intact because routing is still driven by Angular router + ABP packages; the layout is just a host.)

  • For “extract features from lpx-settings (theme + language)” and move them into your toolbar replacement:

    • Language: ABP Angular’s stable state/services are in @abp/ng.core (commonly SessionStateService for language selection + ConfigStateService for reading available languages). This is the same pattern used in ABP Angular UI custom header examples (language list comes from config state, selected culture from session state).
    • Theme switching: LeptonX theme selection is handled by the LeptonX theme packages. The stable/official guidance is: if you need behavior beyond the exposed UI, you either (a) replace the LeptonX UI piece via component replacement and reuse the public services exposed by the package, or (b) pull theme source code and build against it (see “Source access” below). Public documentation does not fully enumerate internal theme-service contracts for lpx-settings (so relying on undocumented internals is not upgrade-safe).
  • For replacing lpx-navbar while keeping “active route detection, collapse state, grouped/child menu items, permission-based visibility”:

    • The upgrade-safe way is still: replace the navbar slot and build your navbar using ABP Angular’s menu/permission infrastructure (rather than copying LeptonX internal navbar logic).
    • ABP Angular provides permission-aware rendering helpers (e.g., *abpPermission="...") and menu data is provided by ABP’s Angular packages; LeptonX’s navbar is ultimately a renderer over that data. (Public docs do not provide a “supported internal navbar service contract” for LeptonX itself; so the supported approach is replace the UI and consume ABP Angular’s menu/permission APIs rather than LeptonX internals.)
  • For toolbar user info + login/logout/profile actions + custom entries:

    • If you only need to customize the user dropdown items, ABP Angular provides UserMenuService to remove/patch/add items (this is used in official support guidance; the key point is to apply changes after currentUser becomes authenticated, because the menu can be (re)built around login/tenant changes).
    • If you need to replace the entire toolbar container, do it with component replacement and implement user actions in your component (calling ABP AuthService / navigation helpers as needed).
  • Source access / sample:

    • Official support guidance is: you can download LeptonX source code via ABP Suite (commercial customers). This is the intended way if you need to clone LeptonX components and customize deeply, beyond what public APIs expose.
    • There is also a documented CLI approach in community material (abp get-source Volo.Abp.LeptonXTheme), but the verified/official support answer we can cite is: ABP Suite download source code.

Practical mapping to your 4 goals (what’s officially safe)

  1. Replace lpx-toolbar-container
  • Supported: ReplaceableComponentsService + the relevant eThemeLeptonXComponents.* key (toolbar slot).
  • Then implement your own toolbar and use ABP Angular services (auth/current user/menu/user-menu) inside.
  1. Move theme/language out of lpx-settings and into your toolbar
  • Supported: Replace toolbar UI and implement language switching via ABP Angular session/config services.
  • Theme switching: either use the public LeptonX theming APIs if they are exposed by your LeptonX version, or pull LeptonX source code and reuse its implementation. Public docs do not fully describe “setting groups” APIs for lpx-settings as stable contracts.
  1. Replace lpx-navbar
  • Supported: Replace the navbar slot via ReplaceableComponentsService, and render menu items using ABP Angular menu + permission primitives (rather than depending on LeptonX internal navbar services).
  1. Replace the overall layout (abp-dynamic-layout host)
  • Supported: ABP Angular “replace a layout” mechanism (component replacement) while keeping <abp-dynamic-layout /> at the root so ABP keeps routing/layout resolution.

Where to get the component code to clone

  • Officially supported: Download LeptonX source code via ABP Suite, then copy/modify the components you want and register them via component replacement.

  • ABP currently does not provide an “official ABP Documentation MCP server” (i.e., a public MCP endpoint that exposes abp.io docs as MCP resources/tools) that you can plug into Claude Code/Codex in the same way as shadcn/ui’s doc MCP page.
  • What ABP does provide today is MCP support around ABP Studio, not the public documentation website:
    • ABP Studio runs a local MCP server and exposes it via the abp mcp-studio bridge so MCP clients (Cursor / Claude Desktop / VS Code) can connect and use ABP Studio’s tools/context.

If your goal is to request an official ABP Docs MCP server (like the shadcn example), that’s a product/feature request. Please contact the ABP team here:

  • CMS Kit / CMS Kit Pro is ready to use in microservice solutions, but it does not come with a ready-made React “news/blog” UI that you can drop into your React app.
  • The typical approach for “news articles” is to use CMS Kit’s Blogging feature (blog + blog posts) or Pages (if you want URL-based pages). Draft/publish is handled on the CMS side via the module’s management UI; consumption (listing/detail) is your responsibility if you’re using React without the MVC public website.

1) What you should implement for a “News” feature

  1. Use CMS Kit Blogging as “News”:
    • Create a “News” blog in CMS Kit admin.
    • Add posts (draft/review/publish flow as provided by CMS Kit management experience).
  2. In your React app, create:
    • GET /news list page (fetch blog posts)
    • GET /news/:slug detail page

2) How to add CMS Kit Pro to a microservice + modern (React) solution

  1. Add the module to the relevant microservice (the one that will own the CMS data/endpoints) using the standard microservice module installation approach.
  2. Enable CMS Kit / CMS Kit Pro global features in the solution (via GlobalFeatureConfigurator), then create migrations and update the DB in that service.

Use the official “add module to microservice” guide for the gateway/routes/migrations/connection-string mapping aspects (this is the definitive integration doc for microservices).

3) Do you need to build the React frontend yourself?

Yes for the public-facing pages (news list/detail) in your React app.

ABP’s React direction is “source-owned UI” (your pages live in your React app), while administration is handled by the pre-built React Admin Console. There isn’t an official “CMS Kit provides ready React public pages/widgets you can reuse” story in the verified sources.

4) Are there examples you can use?

  • There is an official CMS Kit demo app you can reference for feature usage and overall behavior (it’s not React-based, but it’s the canonical sample for how CMS Kit is used end-to-end).
  • For your microservice wiring, follow the official microservice “add module” guide.

5) Should you build your own CMS instead?

If your requirement is “draft/publish news articles + store content + management UI”, CMS Kit / CMS Kit Pro is the intended ABP module for that. You’ll just implement the React pages that display the content.

  • Built-in support: Yes — ABP already supports an explicit deny (subtractive) decision via Permission Value Providers. A provider can return PermissionGrantResult.Prohibited, and if any provider returns Prohibited, the final result is always prohibited (even if user/role providers granted it). This matches your “never grant, only subtract” requirement.
  • Recommended extension point: Implement a custom PermissionValueProvider (or IPermissionValueProvider) and register it in AbpPermissionOptions.ValueProviders. In that provider, read:
    • the current user id from context.Principal (claim AbpClaimTypes.UserId)
    • the channel from the request context (typically a claim, header, or client id claim)
    • your own storage/table keyed by (UserId, PermissionName, Channel) and return Prohibited when there is a block rule; otherwise return Undefined so normal ABP granting continues.

Example skeleton:

using System;
using System.Threading.Tasks;
using Volo.Abp.Authorization.Permissions;
using Volo.Abp.Security.Claims;

public class ChannelBlockPermissionValueProvider : PermissionValueProvider
{
    public const string ProviderName = "ChannelBlock";

    public override string Name => ProviderName;

    public ChannelBlockPermissionValueProvider(IPermissionStore permissionStore)
        : base(permissionStore)
    {
    }

    public override async Task<PermissionGrantResult> CheckAsync(PermissionValueCheckContext context)
    {
        var userIdString = context.Principal?.FindFirst(AbpClaimTypes.UserId)?.Value;
        if (!Guid.TryParse(userIdString, out var userId))
        {
            return PermissionGrantResult.Undefined;
        }

        // Example: determine channel from a claim/header you add to the principal
        var channel = context.Principal?.FindFirst("channel")?.Value; // "Mobile" / "Api"
        if (string.IsNullOrWhiteSpace(channel))
        {
            return PermissionGrantResult.Undefined;
        }

        // TODO: query your table: (userId, context.Permission.Name, channel) => IsBlocked
        var isBlocked = await /* your store */ Task.FromResult(false);

        return isBlocked
            ? PermissionGrantResult.Prohibited   // subtractive deny
            : PermissionGrantResult.Undefined;   // let role/user grants decide
    }
}

Register it:

Configure<AbpPermissionOptions>(options =>
{
    options.ValueProviders.Add<ChannelBlockPermissionValueProvider>();
});
  • Explicit denial in ABP permission storage (PermissionGrant): ABP’s built-in PermissionGrant storage is designed around provider-based grant state; your scenario is a contextual deny (user+permission+channel), so the supported way is not to try to encode this into PermissionGrant, but to use a custom permission value provider and your own persistence. (ABP’s provider pipeline already supports the deny outcome via PermissionGrantResult.Prohibited.)
  • Client side (/api/abp/application-configuration):
    • By default it returns a single grantedPolicies map for the current principal.
    • To make it channel-aware, the supported approach is to ensure the same principal context (including your “channel” indicator claim/header -> transformed into claim) is present when that endpoint is called, then the permission checks performed server-side will reflect your Prohibited results.
    • If you need the returned permission set to differ by channel even for the same logged-in user, you must make the request channel-identifiable (e.g., a header like X-Channel: Mobile + middleware/claims transformation that adds channel claim to the principal before permission evaluation). Then the normal ABP permission evaluation used by application configuration will naturally produce the channel-specific result.
  • In-scope or application code? The framework provides the correct hook (permission value provider + Prohibited semantics). The channel-specific rule storage and how you detect “channel” is expected to be implemented in application/module code.

  • No — ABP 10.1.1 targets Angular 21 (its Angular UI packages/templates are aligned with Angular 21), so Angular 22 is not supported/compatible for ABP 10.1.1.

  • If you want to use Angular 22, you should upgrade ABP to a version that upgraded its Angular UI stack to Angular 22 (ABP 10.6).
