• (1) Managed Identity support in ABP’s Azure Blob provider (v10.2.0):
  In ABP 10.2, the built-in Azure Blob Storage provider is configured via azure.ConnectionString and the documentation describes it as using the connection string (shared key) model. There is no documented option (in ABP 10.2 docs) to pass an Azure.Core.TokenCredential (e.g., DefaultAzureCredential / ManagedIdentityCredential) to the provider.

• (2) Recommended extension/customization point:
  ABP explicitly documents that AzureBlobProvider is the main class and can be overridden/replaced via dependency injection (replace the AzureBlobProvider class, not IBlobProvider). So the supported approach is:

  1. Create your own provider class (either replace AzureBlobProvider via DI or create a custom blob provider).
  2. In your implementation, initialize BlobServiceClient using new BlobServiceClient(new Uri(accountUrl), new DefaultAzureCredential()) (or ManagedIdentityCredential) and implement required blob operations.

  Practically, the most “ABP-aligned” options are:

  • Replace AzureBlobProvider via DI (recommended if you want to keep container.UseAzure(...) configuration style and just change authentication/initialization internals).
  • Or create a custom provider and switch containers to ProviderType = typeof(YourProvider) (recommended if you want a clean separation and your own strongly-typed provider configuration options).

• (3) Roadmap plans:
  No verified source available for ABP’s roadmap regarding “Azure SDK credential-based authentication for Azure Storage” (Managed Identity / TokenCredential) in the built-in provider.

• (4) Samples / best practices published by ABP:
  No verified official ABP sample/documentation demonstrating Azure Blob Storage integration using Managed Identity. The available docs and community articles primarily show connection-string based configuration.

• In ABP’s Microservice startup template, each “service” is intentionally kept minimal (typically HttpApi + Application.Contracts + tests) because ABP expects you to put the actual business layers (Domain/Application/EFCore, etc.) into separate modules/bounded contexts that can be deployed as microservices or plugged into a monolith. In other words: in ABP microservices, the layered architecture is achieved via modules, not by forcing every microservice host to contain every layer project.
• To get a per-service layered structure like Domain / Application / EntityFrameworkCore / HttpApi / Application.Contracts / tests, you should create each microservice as an ABP module solution (microservice-first module design) and then host it with a small HttpApi.Host (or similar) project.
  • Practical approach:
    1. Create a new module solution for your bounded context/service (this module will contain the layers you want: Domain, Domain.Shared, Application, Application.Contracts, EntityFrameworkCore, HttpApi, etc.).
    2. Create (or keep) a thin service host project (your microservice’s running API) that references that module’s *.HttpApi (and usually *.EntityFrameworkCore) and configures the database connection / migrations.
    3. Deploy that host as the microservice.
• If you want a real working reference showing how ABP microservices are organized, use eShopOnAbp as a guide and model your bounded contexts similarly (each bounded context is effectively a module with its own layers; the “service host” stays thin).

• Yes, calling Identity from your WorkItem microservice and mapping AssignedUserId -> UserName in your custom list DTO is the correct approach for a microservice solution.
• Adding an HttpApi.Client package (and using the generated client proxy) is exactly how ABP expects you to do synchronous inter-service communication.

That said, in microservices you should prefer calling Identity’s Integration Service (if available in your version/package set) rather than the full “UI/admin” Identity app service endpoints, because integration services are designed specifically for service-to-service scenarios.

What to do

1. Keep AssignedUserId as Guid in WorkItem (no EF navigation to IdentityUser).

2. In WorkItemsAppService.Extended.cs, implement GetListWithUsernameAsync like:

   • get WorkItems from your DB
   • extract distinct AssignedUserIds
   • call Identity remotely (client proxy) to fetch users
   • fill AssignedUserName on your DTOs

3. Ensure your microservice can forward the current user’s access token to the Identity service when doing remote calls. In ABP microservices this is handled by the Volo.Abp.Http.Client.IdentityModel integration (commonly used by microservice hosts) so the outgoing request contains the Authorization header.

Notes about the package name you mentioned

• Using an Identity .HttpApi.Client package is the right idea.
• Whether you should use Volo.Abp.Identity.Pro.HttpApi.Client specifically depends on what your solution uses (Pro vs non-Pro) and which endpoints you need. The key is: use the Identity service’s HttpApi.Client (client proxy) for remote calls, not EF references.

• In a microservice solution you generally should not create an EF Core navigation property / foreign key to IdentityUser inside another microservice’s database, because IdentityUser lives in the Identity microservice (its own bounded context + its own database). That’s why ABP Studio/Suite doesn’t offer “Identity” as a selectable module entity for a navigation property in your WorkItem entity designer.

• The recommended approach is:

  1. Keep AssignedUserId : Guid in WorkItem (as you already do).
  2. When listing WorkItems, enrich the DTO with the user’s display text by calling the Identity microservice (remote call) and mapping AssignedUserId -> UserName (or Name + Surname, etc).
  3. Optionally use a lookup endpoint from Identity to pick users in the UI.

Concrete implementation (typical pattern)

1. Add a display field to your list DTO (in your WorkItem application contracts), e.g.:

public class WorkItemDto : EntityDto<Guid>
{
    public Guid? AssignedUserId { get; set; }
    public string? AssignedUserName { get; set; } // <- add this
}

2. In your WorkItem AppService list method:

• Query WorkItems from your own DB.
• Collect distinct AssignedUserIds.
• Call Identity service to get corresponding users.
• Populate AssignedUserName.

(How you call Identity depends on your solution’s existing microservice client setup, but conceptually you do a remote call to Identity’s user endpoints and join in-memory.)

About “Do I have to add a package to my WorkItem service before I can reference AbpUsers?”

• You should not add an EF entity reference to Volo.Abp.Identity.IdentityUser in another microservice’s domain model to create an EF relationship.
• If you need user info, use remote service calls / client proxies to Identity instead of a direct EF navigation property.

If you want ABP Studio/Suite “reference entity” support

ABP Studio’s low-code “Reference Entities” list includes Identity User as a reference entity (for lookup/display purposes), not as a local EF navigation target in another microservice DB:

• Volo.Abp.Identity.IdentityUser (typical display property: UserName)

Validated source:

• https://abp.io/docs/10.4/low-code/reference-entities

Background: Identity is a separate microservice

Validated source:

• https://abp.io/docs/10.2/solution-templates/microservice/microservices

Extra (non-microservice / monolith note)

There is an article showing adding a user navigation property via Suite in a monolith-style setup (where user entity is in the same solution/bounded context). This is generally not the right model for microservices:

• CMS Kit Pro Newsletter is a subscription management feature (subscribe/unsubscribe, list subscribers, export to CSV). It does not include built-in email delivery / campaign management (no “create campaign”, “compose email”, “send to subscribers” UI or app service in the module).

• Recommended approach is to implement your own “campaign sender” (or integrate an external provider) and use CMS Kit Pro Newsletter only as the subscriber store:

  1. Get subscribers (from CMS Kit Newsletter subscription data; e.g., by category if you use categories).
  2. Render email content (recommended: ABP Text Template system so admins can edit templates without redeploying).
  3. Send emails using ABP’s emailing infrastructure (IEmailSender), typically via QueueAsync(...) to avoid blocking and to use background jobs.
  4. Optional: store “campaigns”, “sent items”, “failures”, “unsubscribe links”, tracking, etc. in your own tables, because CMS Kit Pro Newsletter doesn’t provide these.

• If you don’t want to build this yourself, the practical alternative is exactly what you suggested: export subscribers (CSV) and use an external email marketing provider (SendGrid / Mailchimp / etc.) for campaigns, scheduling, analytics, throttling, bounce handling, etc.

• In ABP React UI, the Setting Management page does not automatically create a new tab/group just because you added SettingDefinitions. Defining settings only makes them available to the backend (and to the client if isVisibleToClients: true), but the admin UI tabs are contributed explicitly by the UI package/module.

• The recommended/standard way to add a new “tab” (group) in the Administration → Settings (Setting Management) UI is:

  1. Define your settings (you already did with SendGridSettingDefinitionProvider).
  2. Create an application service that reads/writes those settings (typically using ISettingProvider + ISettingManager).
  3. Add a custom UI group to the Setting Management page:
     • For MVC/Blazor/Angular there are documented “custom setting group” contribution mechanisms in the Setting Management module docs.
     • For React, there isn’t an equivalent “auto-discover my setting definitions and render them as a tab” mechanism in the same way; you typically create your own page/component and wire it into the admin menu, or extend the setting-management UI in the way that UI package exposes (if it does for your version). If you were trying to drop a pSendGridSettings.tsx under src/pages/settings, that won’t work unless your React app’s routing/menu is configured to load it.

• Backend part (what you should keep / adjust):

  • Keep isVisibleToClients: true for non-secret values.
  • Keep isEncrypted: true for ApiKey (good).
  • Don’t expect this to create an admin tab by itself; it only makes the setting available.

• Practical approach for React (works reliably):

  1. Create an app service like:

public class SendGridSettingsAppService : ApplicationService
     {
         private readonly ISettingProvider _settingProvider;
         private readonly ISettingManager _settingManager;

         public SendGridSettingsAppService(ISettingProvider settingProvider, ISettingManager settingManager)
         {
             _settingProvider = settingProvider;
             _settingManager = settingManager;
         }

         public async Task<SendGridSettingsDto> GetAsync()
         {
             return new SendGridSettingsDto
             {
                 Enabled = await _settingProvider.GetAsync<bool>(SendGridSettings.Enabled),
                 FromName = await _settingProvider.GetOrNullAsync(SendGridSettings.FromName),
                 FromAddress = await _settingProvider.GetOrNullAsync(SendGridSettings.FromAddress),
                 ApiKey = await _settingProvider.GetOrNullAsync(SendGridSettings.ApiKey)
             };
         }

         public async Task UpdateAsync(SendGridSettingsDto input)
         {
             await _settingManager.SetGlobalAsync(SendGridSettings.Enabled, input.Enabled.ToString());
             await _settingManager.SetGlobalAsync(SendGridSettings.FromName, input.FromName);
             await _settingManager.SetGlobalAsync(SendGridSettings.FromAddress, input.FromAddress);
             await _settingManager.SetGlobalAsync(SendGridSettings.ApiKey, input.ApiKey);
         }
     }

 (Then generate the React service proxies and build a custom admin page that calls `GetAsync/UpdateAsync`.)

2. Add a new admin menu item in React to navigate to your “SendGrid Settings” page (instead of trying to make it appear automatically under the Setting Management tabs).

• If you specifically want it inside the built-in Setting Management UI: follow the Setting Management module’s “custom setting group” approach shown in the docs (note: the docs show this clearly for MVC/Blazor/Angular; React doesn’t have the same “drop-in contributor” story documented there).

• This exception is not an ABP-specific bug; it’s coming from ASP.NET Core Data Protection during Blazor Server prerendering/persisted state (ComponentStatePersistenceManager.PersistStateAsync()), when it tries to encrypt data:

  • CryptographicException: ... encrypt the provided data
  • Inner exception: Could not load file or assembly 'Microsoft.Win32.Registry, Version=8.0.0.0'

• The reason Swagger works but “the page” fails is that Swagger is just serving middleware/UI and usually doesn’t hit Blazor Server prerender persistence. The Blazor page pipeline does, so it triggers Data Protection encryption.

Fix (recommended)

1. Ensure the app is running with the full .NET 8 runtime (not trimmed / not missing framework assemblies).

   • This error typically happens when deploying in an environment/container where the Microsoft.Win32.Registry runtime assembly isn’t available (common with certain Linux/container publish setups or incorrect runtime installation).

2. If you deploy with Docker, use an official ASP.NET 8 runtime base image (so the runtime packs include needed assemblies), e.g. mcr.microsoft.com/dotnet/aspnet:8.0 (or matching patch).

   • Rebuild and redeploy after switching base image.

3. Configure Data Protection key storage explicitly (especially for IIS/containers), so key ring operations don’t rely on defaults that may differ per environment.

   • In your *.Web (Blazor Server) project module or Program.cs, configure DataProtection to persist keys to a known folder (mounted volume in containers; writable folder in IIS):

using Microsoft.AspNetCore.DataProtection;
   using System.IO;

   builder.Services.AddDataProtection()
       .PersistKeysToFileSystem(new DirectoryInfo(Path.Combine(builder.Environment.ContentRootPath, "DataProtection-Keys")));

4. Make sure the app process identity can read/write that folder.
   • IIS: grant write permission to the AppPool identity for DataProtection-Keys (or your chosen path).

If you are on IIS and also using OpenIddict certificates (common in ABP templates)

If you are also loading openiddict.pfx in production, ensure IIS can load the cert and the private key correctly (this often requires Load User Profile = true and/or key storage flags). ABP has a dedicated guidance for this scenario and it’s closely related to crypto failures on IIS.

• Issue 1 (Shared Accounts – “Leave Tenant” doesn’t update Host user / tenant list still shown):
  With Shared User Accounts (TenantUserSharingStrategy.Shared), the “leave tenant” action doesn’t primarily rely on flipping the Leaved flag on a tenant AbpUsers row. Instead, ABP maintains a host-side membership/association for the user↔tenant relationship, and “Leave” marks that membership as left so the tenant no longer appears in the tenant switcher list.

  In your migration, you manually created host AbpUsers rows for tenant users (which is required for database-per-tenant scenarios), but for pre-migration tenants it sounds like the user↔tenant association data wasn’t created/matched correctly. As a result, the “Leave Tenant” operation updates something in the tenant DB (you see Leaved = 1), but the host-side association that drives the visible tenant list remains effectively “joined”.

  What to do (verified approach):

  1. Ensure you migrated not only users, but also the shared-accounts tenant membership/association records in the Host database (the thing that backs “Switch Tenant” / “Leave”).
     If these association rows are missing or don’t match the same UserId across host and tenant databases, host will still think the user is a member, and the tenant will remain visible after login.
  2. Re-run/implement a migration step that, for every existing tenant user, creates the proper host-side membership record linking that single global (host) user id to the tenant.
     (ABP’s docs explicitly call out that for separate databases you must ensure host DB contains the matching user records, then “the framework can create/manage the user-to-tenant associations”. If you created users manually, you also need to ensure the associations are consistent.)
  3. After fixing associations, “Leave Tenant” should correctly remove the tenant from the switch list because the membership is marked left/inactive.

• Issue 2 (No “Delete” action for users in Identity Management UI):
  In ABP, deleting identity users from the UI is typically governed by permissions. If the current admin account doesn’t have the delete permission, the UI won’t show the delete action.

  What to do:

  1. Go to Administration → Identity Management → Roles.
  2. Edit the role of your current admin (often admin) and open Permissions.
  3. Grant the user deletion permission under the Identity permissions (the “delete user” permission).
  4. Refresh the page; the “Delete” action should appear in the user actions menu.

• Yes: configuring AppUrlOptions is the correct/expected way to make Account module email links (forgot password / reset password / email confirmation, etc.) point to the correct UI host, including tenant-specific subdomains.
• ABP’s Account emails build links via the App URL system (AppUrlOptions + IAppUrlProvider). If options.Applications["MVC"].RootUrl (or your relevant UI key) is set to a non-tenant-aware host URL, the generated link will also be non-tenant-aware—exactly what you observed.

To make links tenant-aware for a subdomain setup, setting a template RootUrl is the right approach, e.g.:

Configure<AppUrlOptions>(options =>
{
    // Use the UI application's key that Account uses for link generation in your solution
    options.Applications["MVC"].RootUrl = "https://{0}.example.com";
});

Notes / side effects (what to expect)

• {0} is the placeholder ABP uses to inject the current tenant name when generating URLs (similar to how it’s used in the domain/subdomain tenant resolver).
• This impacts only URLs generated through ABP’s URL system for that application key (including Account emails and other places that call IAppUrlProvider), which is typically what you want in a subdomain-per-tenant setup.
• If you also need to support host (no-tenant) URLs, ABP will generate host URLs when there is no current tenant (it won’t have a tenant name to substitute). In practice, many solutions handle host separately by using a non-templated RootUrl for host and a templated one for tenant scenarios; but the safe/official mechanism remains configuring AppUrlOptions.
