• This error is thrown by AspNetCore.Diagnostics.HealthChecks UI’s background collector (HealthChecks.UI.Core.HostedService.HealthCheckCollectorHostedService). In some dependency graphs (commonly after upgrading ABP to v10), the IdentityModel assembly that HealthChecks.UI expects is not copied to the output, so the hosted service crashes repeatedly with:

  Could not load file or assembly 'IdentityModel, Version=5.2.0.0'

• Fix (recommended): add an explicit package reference to IdentityModel in the project(s) where you call AddHealthChecksUI() / MapHealthChecksUiEndpoints() (typically *.HttpApi.Host, and in some solutions also *.Web):

  Option A (match the requested assembly version exactly):

<ItemGroup>
    <PackageReference Include="IdentityModel" Version="5.2.0" />
  </ItemGroup>

Option B (use the newer version ABP team suggested in a similar case):

<ItemGroup>
    <PackageReference Include="IdentityModel" Version="7.0.0" />
  </ItemGroup>

• Then:

  1. dotnet clean
  2. delete bin/obj for the affected host project(s)
  3. dotnet restore
  4. rebuild + run

• If you have multiple hosts/services each registering HealthChecks UI, add the reference to each of those host projects (only where the UI collector runs).

• In your case the key detail is you created the solution with ABP Studio, then upgraded packages to 10.5.0. ABP Suite’s Blazor templates (the missing ...Blazor.Page.Partials.Modal.Field.DateTime.NonNullable.txt) are taken from the exact Volo.Abp.Commercial.SuiteTemplates version that your solution actually resolves and builds with. When you upgrade afterwards, it’s common that some projects still resolve an older Volo.Abp.Commercial.SuiteTemplates (or an older output DLL is still what Suite loads) even though the main app runs.

Do this “hard verification + forced alignment” sequence

1. Verify what version your solution really resolves for SuiteTemplates Run this in the solution folder (pick the main host project you run; typically *.HttpApi.Host.csproj or *.Web.csproj):

dotnet list path\to\YourHostProject.csproj package --include-transitive | findstr /i "Volo.Abp.Commercial.SuiteTemplates"

• If this prints anything other than 10.5.0, Suite will fail exactly like you see.
• Fix it at the version-management root (usually Directory.Packages.props / central package management) so it is exactly 10.5.0.

2. Clear NuGet caches (bin/obj clean is sometimes not enough)

dotnet nuget locals all --clear
   dotnet restore

3. Hard clean outputs again, then rebuild
   • Close IDE
   • Delete all bin and obj under the whole solution
   • Rebuild:

dotnet build

4. Make sure ABP Suite is not launching another installed copy

   • Ensure only one ABP Suite is installed and it is 10.5.0.
   • If you have multiple installations (common via Studio + standalone), uninstall the extras and keep only 10.5.0.

5. Retry entity generation

   • Remove/re-add the solution in Suite (you did)
   • Generate again

If steps (1)-(4) are correct, the missing template resource error disappears because Suite will load a Volo.Abp.Commercial.SuiteTemplates assembly that actually contains the 10.5.0 Blazor templates.

• This error means ABP Suite is running with a different template set than the one your solution outputs contain. In ABP, Suite reads its generation templates from the Volo.Abp.Commercial.SuiteTemplates assembly produced by your solution build, so ABP Suite version and Volo.Abp.Commercial.SuiteTemplates package version must match, and the solution must be built with a clean output.

Fix (do in this exact order)

1. Make sure ABP Suite is exactly the same version as your solution (10.5.0)

   • Update/downgrade ABP Suite so the installed Suite version is 10.5.0 (not 10.5.x vs 10.5.0 mismatch).
   • If you have multiple Suite versions installed, remove the others so you don’t accidentally launch a different version.

2. Make sure your solution references Volo.Abp.Commercial.SuiteTemplates = 10.5.0

   • Check the version in your solution (often centrally managed via Directory.Packages.props / Directory.Build.props).
   • Ensure it is exactly 10.5.0 everywhere.

3. Hard clean outputs (most common cause)

   • Close Visual Studio/Rider completely.
   • Delete all bin and obj folders under the entire solution (every project).
   • Reopen the solution and rebuild.

4. Build the solution once after the clean

   • Build the full solution (or at least the main host project that Suite uses).
   • Then open ABP Suite and retry the generation.

If you do (1)-(4), Suite will load the correct SuiteTemplates resources and the missing template error (e.g., ...Blazor.Page.Partials.Modal.Field.DateTime.NonNullable.txt) will disappear.

• For an internal ERP refactor, starting with a Modular Monolith is a good, future-proof choice in ABP (you keep clear bounded contexts/modules and can still deploy as one app; later you can split out services only if/when you truly need it).
• You’re not missing a step: in ABP’s modern template system, React is the UI option you’ll see in that “Modern + Modular Monolith” flow. That’s why it looks React-only in ABP Studio/Suite.
• Blazor is important in ABP, but it is not mandatory. ABP supports multiple official UI options; you should pick the one that best matches your team skills and UI complexity. Since you also need to reuse APIs for a mobile app, ABP’s backend (HTTP APIs, auth, permissions, etc.) fits well regardless of whether the web UI is React, Angular, MVC/Razor Pages, or Blazor.

Practical guidance for your case

• If you want a modern SPA and expect dense/custom UI screens: choose React (modern template). Your mobile app can consume the same backend APIs.
• If your team prefers C# end-to-end and a component-based UI inside .NET: choose Blazor (ABP supports it as a first-class UI option; you can also choose different Blazor UI libraries such as Blazorise/MudBlazor depending on your ABP version and preferences).
• If you want the most traditional server-rendered web approach: choose MVC / Razor Pages.
• If you already have Angular skills (or want Angular’s ecosystem): Angular is also a supported option.

• ABP AI Management does not currently ship a SQL Server vector-store provider.
• As of the verified AI Management docs, the built-in vector store providers are MongoDb, Pgvector, and Qdrant (installed via their respective Volo.AIManagement.VectorStores.* packages). There is no mention of SQL Server as a supported vector store provider.
• Regarding “roadmap”: the publicly available/verified ABP AI Management roadmap items (preview announcement / future goals) do not list a SQL Server vector-store provider, so there is no verified public commitment that it’s planned.

If you need SQL Server vectors now, the supported approach in ABP is to implement a custom vector store provider (register your own factory so it appears in the “Vector Store Provider” dropdown) and integrate SQL Server’s vector features behind that abstraction.

• In LeptonX (MVC) the topbar/sidebar UI pieces are re-initialized after partial page updates (ABP’s dynamic DOM updates / SPA-like navigation). When that happens, LeptonX can replace (or re-render) the menu/link/badge elements, so the elements you updated are no longer the “live” ones. The symptom is exactly what you described: you see the visual DOM once, but later your updates don’t reflect, because you’re updating a stale node or your changes are overwritten by the theme’s initializer.

• Fix: Treat LeptonX-rendered DOM as disposable and always re-apply your badge/list rendering after ABP DOM updates using ABP’s DOM API, and always query the DOM at the time you update (never cache element references). Concretely:

  1. Wrap all your “apply UI state” into a single function (applyUnreadCountToDom).
  2. Call it after every fetch and inside abp.dom.onNodeAdded (ABP DOM API) so it runs when LeptonX/ABP re-adds the toolbar node.
  3. Avoid duplicate IDs across re-renders; scope your selector under #notification-bar (you already started doing this—keep it everywhere, including #NotificationNewBadge, which can also become duplicated if the toolbar re-renders).

Here is the minimal pattern that works reliably with LeptonX + ABP dynamic DOM updates (drop-in concept; adapt into your current script):

<script>
(function () {
  'use strict';

  var state = { unread: 0 };

  function applyUnreadCountToDom() {
    // Always re-query (never keep old references)
    var bar = document.getElementById('notification-bar');
    if (!bar) return;

    var badge = bar.querySelector('.menu-item-badge');
    if (badge) {
      badge.setAttribute('data-count', state.unread);
      badge.textContent = state.unread > 99 ? '99+' : String(state.unread);

      // If your CSS uses opacity/visibility, toggle them here too (optional)
      if (state.unread > 0) {
        badge.style.opacity = '1';
        badge.style.visibility = 'visible';
      } else {
        badge.style.opacity = '0';
        badge.style.visibility = 'hidden';
      }
    }

    // IMPORTANT: scope this too (don’t use global #NotificationNewBadge if toolbar can re-render)
    var newBadge = bar.querySelector('#NotificationNewBadge');
    if (newBadge) {
      newBadge.setAttribute('data-count', state.unread);
      newBadge.textContent = state.unread + ' NEW';
      newBadge.style.opacity = state.unread > 0 ? '1' : '0';
      newBadge.style.visibility = state.unread > 0 ? 'visible' : 'hidden';
    }
  }

  function fetchCount() {
    if (!window.abp?.ajax) return;

    abp.ajax({
      url: (abp.appPath || '') + 'api/notification/private-message/unread-count',
      type: 'GET',
      success: function (response) {
        var num = parseInt((response && response.result != null) ? response.result : response, 10) || 0;
        state.unread = num;
        applyUnreadCountToDom();
      }
    });
  }

  // 1) Initial run
  fetchCount();

  // 2) Re-apply after ABP adds/replaces DOM nodes (LeptonX/toolbar redraw)
  // This is the key difference vs. only using abp.event / setInterval.
  if (window.abp?.dom?.onNodeAdded) {
    abp.dom.onNodeAdded(function (node) {
      // Only react when our toolbar node is added/replaced
      if (node && node.id === 'notification-bar') {
        applyUnreadCountToDom();
      }
    });
  }

  // 3) Polling (as you already do)
  window.__notificationPollTimer = window.__notificationPollTimer || setInterval(fetchCount, 30000);
})();
</script>

What this changes vs your current approach:

• Your current logic mostly relies on abp.event.on('abp.domUpdated', ...). In LeptonX scenarios, the safer hook is ABP DOM API node-added detection (abp.dom.onNodeAdded), because it runs when the actual node is reinserted/replaced, and you immediately re-apply your state to the fresh DOM.
• It also fixes the common “duplicate IDs after toolbar re-render” issue by scoping everything under #notification-bar.

If you still want to keep abp.event.on('abp.domUpdated', ...), keep it, but you should still add the abp.dom.onNodeAdded hook above; that’s the part that makes the DOM updates deterministic with LeptonX redraws.

• No, ABP 10.4.1 does not require a dedicated worker app just to send emails. The built-in background job worker can process email jobs inside the same web host, as long as background job execution is actually enabled and there is no NullEmailSender replacement in that host.

• In your case the key signal is: Email Confirmation is also not sent. That strongly indicates this is not “MFA-specific”, but rather one of these common post-migration causes:

  1. The host that enqueues/processes the job is using NullEmailSender (often added under #if DEBUG in the host module, or effectively happening due to environment/config differences after migration).
  2. Background jobs are being written to AbpBackgroundJobs, but not executed (job worker not running, disabled, or running in a different process than you think).

What to do (verified ABP behavior)

1. Check for NullEmailSender replacement in your web host (the app that runs the login/registration pages)
   • Search in your Host/AuthServer module for code like:

#if DEBUG
     context.Services.Replace(ServiceDescriptor.Singleton<IEmailSender, NullEmailSender>());
     #endif

• If your app is running with a configuration where that code is active, emails will never be sent (they’ll be swallowed/logged).
• This exact pitfall is confirmed in an ABP support answer: the host can be configured to replace the sender with NullEmailSender in debug builds.
  (Link in sources)

2. Confirm the background job is actually being executed

   • Since you already see rows in AbpBackgroundJobs, verify they are not just accumulating.
   • If the rows remain in a “pending/not processed” state (or never get deleted/updated), then the worker isn’t running.
   • In a single-host MVC app, the same web host should both enqueue and process jobs if enabled.

3. Make sure SMTP settings are configured for the same host that executes the jobs

   • In ABP, email sending is integrated with the background job system (“send emails via background jobs”). So SMTP must be available where the background job runs.
   • If you have multiple hosts/environments, ensure the one processing jobs has the SMTP settings too.

4. Re-check 2FA email provider prerequisites (only after email sending is fixed)

   • Email 2FA codes require the email to be verified/confirmed; ABP’s 2FA doc explicitly calls out that users won’t receive a code if the email/phone isn’t verified.

• ABP Suite’s Angular proxy generation is not incremental and not selective: when you generate proxies, it regenerates the proxy files from the backend API Definition (/api/abp/api-definition). Because of that, it can rewrite already-committed proxy files (remove methods, rename method URLs, etc.) if the server-side API surface it reads differs from what your previously generated employee.service.ts was based on.

• In ABP (including v10.4), the generated Angular URLs come from server metadata, not from the existing TypeScript file. So when you regenerate proxies, the tool will:

  1. drop methods that are no longer present (or no longer discoverable) in the API definition (e.g., GetEmployeeLookup disappears),
  2. update URL templates if the backend action’s “effective route” changed (or if the backend action name/route attributes changed), and overwrite the TS file accordingly.

• Practical resolution (to stop proxy generation from breaking already-committed code):

  1. Do not manually edit generated proxy files under src/app/proxy/**. Treat them as generated artifacts.
  2. Wrap/adapter pattern: create your own Angular service (e.g., employee-api.service.ts) that calls the generated proxy service, and only commit/use your wrapper in business code. Then proxy regeneration won’t break your app code, only the generated layer.
  3. If you must keep stable URLs like /api/app/employees/grade-lookup etc., make sure the backend controller/action routes are explicitly fixed with attributes (e.g., [Route("api/app/employees")] on the controller + [HttpGet("grade-lookup")] on the action), and that these endpoints are visible in /api/abp/api-definition. Then regenerate proxies; the generated URLs will match those explicit routes.

• If your backend code truly still has the old routes but the generator produces /employee-grade-lookup style paths, that indicates the backend API definition being used during generation is not the one you think (common causes: generating against a different host/port, wrong environment, wrong gateway in tiered setup). Fix by generating proxies against the correct running endpoint that exposes the real API definition for that app.

• There is no ABP Suite UI option to generate proxies only for a single entity/service. (So the correct approach is to isolate generated files and rely on wrappers, or regenerate and commit generated output as a whole.)

• In ABP 10.x the email 2FA code is only sent if the user actually has an available/verified 2FA provider. For the Email provider this effectively means: the user’s email must be verified (and similarly for SMS the phone must be verified). If the user doesn’t have a usable provider, ABP/Identity can still redirect to the “enter security code” step, but no code is generated/sent.

• Fix (verify from DB/UI, not only what you “expect” logically):

  1. Open Identity > Users > (your user) > Personal info and ensure the email has the Verified label.
  2. If it’s not verified, verify it (or re-send confirmation and confirm).
  3. Then re-try the login flow; the email 2FA code should be generated and sent.

• Also ensure you didn’t accidentally end up with NullEmailSender in your environment (a common “works elsewhere / not here” symptom after migrations is that one host (AuthServer / HttpApi.Host) is still using a null sender, while another host sends fine). In ABP solutions, the 2FA email is sent by the AuthServer/Host that performs the login, so SMTP must be configured there too.

Reference behavior in ABP docs (this is the key rule that blocks sending the code):

• “Why don't users receive a verification code even 2FA enabled? … This is because the user does not have a verified e-mail or phone number … Ensure that Verified label next to email or phone number …”

• Your post doesn’t include any error/log output, so a definitive “why it fails” can’t be derived from the provided info.
• If by “ABP MCP” you mean MCP servers in ABP Studio / ABP AI Agent, the most common verified causes/fixes are:

1. Update ABP Studio

   • ABP Studio 2.1.9 includes: “Fixed MCP server CLI output problem.”
   • So if your MCP server process starts but Studio can’t read/parse its output (looks like “fails to start”), upgrading to that or newer is the first action.

2. If you upgraded ABP to 10.4 and MCP broke

   • ABP 10.4 includes MCP server integration enhancements specifically affecting stdio transport and workspace relationships.
   • After upgrading, re-test the MCP server connection and tool listing (some configs may need adjustment depending on your setup).

3. If “fails to start” is actually an auth/network block inside Studio

   • Corporate security software can block ABP Studio’s outbound network calls (a real-world confirmed case was Kaspersky restrictions).
   • Ensure abp.io and its subdomains are reachable/allowlisted.
