• Option A (Recommended): Model “common to all tenants” as Host data

  1. Create the shared entities/tables without IMultiTenant (no TenantId column). These are naturally readable by everyone because they are not tenant-filtered.

  2. For tables that need both tenant-specific rows and global rows, implement IMultiTenant and store shared rows with TenantId = null.

  3. When querying from the tenant side, explicitly include both:

     • rows with TenantId == CurrentTenantId
     • rows with TenantId == null (global/shared)

     Example (repository or EF Core query):

var tenantId = CurrentTenant.Id;

     var items = await _repo.GetQueryableAsync();
     var result = await items
         .Where(x => x.TenantId == tenantId || x.TenantId == null)
         .ToListAsync();

 Notes:
 - ABP’s automatic multi-tenancy filter for `IMultiTenant` typically returns only the current tenant’s rows. So for this “tenant + global” scenario, you should **control the predicate yourself** (as above), or use a separate read model/service dedicated to this query pattern.

• Option B (More complex): “Shared across some tenants (not all)”

  • This requirement violates strict multi-tenancy isolation (ABP team explicitly calls out that if tenants must see other tenants’ data, it’s not a pure multi-tenant model).

  • Practical approach in ABP is to model “sharing” explicitly, e.g.:

    1. Keep the record as a host/global record (no TenantId or TenantId = null)
    2. Add a join table like EntityTenantShare(EntityId, TenantId) that defines which tenants can see it
    3. Query with a join / subquery for the current tenant.

    Conceptual example:

var tenantId = CurrentTenant.Id;

     var query = from e in await _entityRepo.GetQueryableAsync()
                 join s in await _shareRepo.GetQueryableAsync() on e.Id equals s.EntityId into shares
                 from share in shares.DefaultIfEmpty()
                 where e.TenantId == tenantId
                       || (e.TenantId == null && share.TenantId == tenantId)
                 select e;

• If you find many tables needing this, consider whether you actually want multi-tenancy in ABP terms, or a “single-tenant app with a Company/Group filter” using ABP Data Filtering (custom filters).

• When you need “not all tables”

  • ABP already supports this naturally: only entities implementing IMultiTenant are tenant-filtered. Others are shared.

• This is not an ABP/Mapperly runtime problem; it’s an IDE design-time compiler / analyzer problem.
• In ABP, defining Mapperly mappers like below is correct and should compile because Mapperly generates the “implementation part” during build:

[Mapper]
public partial class CoreBookToBookDtoMapper : MapperBase<Book, BookDto>
{
    public override partial BookDto Map(Book source);
    public override partial void Map(Book source, BookDto destination);
}

• The CS8795 message (“must have an implementation part because it has accessibility modifiers”) typically appears in the IDE when the editor is not seeing the source-generator output, even though dotnet build does. That’s why runtime/build is fine, but the IDE shows errors.

Fix (practical, ABP-safe)

1. Ensure you build the project at least once (from command line) so Mapperly’s generated code exists:
   • dotnet clean
   • dotnet build
2. Restart the IDE (Visual Studio / Rider). This forces the design-time compiler to reload generated sources.
3. Delete bin/ and obj/ folders for the project(s) containing the mappers, then rebuild.
4. If you use Visual Studio, make sure you are on a recent version (the design-time source-generator pipeline had issues in older VS versions). Upgrading VS usually fixes “generator not picked up in editor” symptoms.
5. Keep your signatures exactly as ABP docs show: public override partial ... (don’t convert them to non-partial, and don’t remove override), because ABP’s MapperBase<TSource,TDestination> is designed for this pattern.

If you follow the steps above, the IDE should stop reporting CS8795 while keeping the correct ABP + Mapperly integration.

• In ABP Blazor (including Blazor Web App) the Identity Users page is a server-side paged list. The order is determined by the Sorting field sent in the GetListAsync request (a PagedAndSortedResultRequestDto / GetIdentityUsersInput-like DTO).
• To sort the list, set a default sorting value (and/or make the grid send the current sorting) by overriding the Identity UserManagement page/component and assigning GetListInput.Sorting.

Option A) Set a default sort (e.g., by UserName)

1. Create a new page/component that replaces the built-in one (same technique used for overriding built-in Identity pages):

@* YourProject.Blazor/Pages/Identity/UserManagement.razor *@
@using Volo.Abp.Identity.Blazor.Pages.Identity
@using Volo.Abp.DependencyInjection

@attribute [ExposeServices(typeof(UserManagement))]
@attribute [Dependency(ReplaceServices = true)]

@inherits UserManagement

2. In the code-behind, set Sorting before loading:

// YourProject.Blazor/Pages/Identity/UserManagement.razor.cs
using System.Threading.Tasks;

namespace YourProject.Blazor.Pages.Identity;

public partial class UserManagement
{
    protected override async Task UpdateGetListInputAsync()
    {
        await base.UpdateGetListInputAsync();

        if (string.IsNullOrWhiteSpace(GetListInput.Sorting))
        {
            // Pick any valid field exposed by the backend DTO:
            // e.g. "UserName", "Name", "Email", etc.
            GetListInput.Sorting = "UserName asc";
        }
    }
}

Now the page will always request users sorted by UserName asc unless the UI sets another sorting.

Option B) Sort based on the grid’s current sorting

If you want clicking column headers to sort, ensure the page sets:

GetListInput.Sorting = CurrentSorting;

(where CurrentSorting is the value produced by the ABP CRUD/grid base page logic). This is the same pattern used in ABP Blazor CRUD pages to pass sorting to the backend.

• Since your mobile app is using the system browser/custom tab, the 400 on "/Account/Login" with missing ".AspNetCore.Antiforgery.*" cookie is almost always a cookie not being stored/sent back during the login POST inside that browser session.
• The iOS-vs-Android difference strongly points to a SameSite/Secure cookie policy / HTTP-vs-HTTPS behavior difference (Android Chrome / Custom Tabs tend to be stricter/behave differently than iOS Safari/WebKit in some setups). When the antiforgery cookie is not persisted/sent, the POST to /Account/Login fails exactly like your log.

Solution

1. Ensure you are using HTTPS end-to-end for the Authority

• Make sure the AuthServer:Authority you use in the mobile OIDC config is https://... (not http://...) and the browser is actually hitting HTTPS.
• If you are testing behind a proxy / ingress, ensure forwarded headers are configured so ASP.NET Core knows the original scheme is HTTPS; otherwise cookies can be emitted without Secure and then dropped/not returned by modern browsers.

2. Apply a SameSite cookie policy workaround (ABP’s documented approach) Add a SameSite cookie policy to deal with browser incompatibilities, then enable UseCookiePolicy() early.

In your *.Web (or the host project that serves the /Account/* pages), add:

ConfigureServices

context.Services.AddSameSiteCookiePolicy();

OnApplicationInitialization (before auth middleware that writes cookies)

app.UseCookiePolicy();

This is the approach used to fix browser-specific login cookie issues.

3. Do not try to disable antiforgery for this Your symptom is not “ABP antiforgery is incorrectly enabled for a non-browser client”; it’s “the browser did not return the antiforgery cookie”. Disabling antiforgery just masks the underlying cookie issue and weakens the login endpoint.

• Your setting Configure<AbpAntiForgeryOptions>(o => o.AutoValidate = false) disables ABP’s global [AbpAutoValidateAntiforgeryToken] behavior for MVC/API endpoints, but your error is coming from Microsoft’s built-in Razor Pages antiforgery filter: Microsoft.AspNetCore.Mvc.ViewFeatures.Filters.AutoValidateAntiforgeryTokenAuthorizationFilter and the failing endpoint is the Razor Page /Account/Login.

• In ABP (with the Account module), /Account/Login is a Razor Page and it’s expected to be protected by antiforgery because it is a cookie-based, browser login page. For mobile OIDC (Authorization Code + PKCE), you typically should not POST to /Account/Login from the mobile app at all. The mobile app should start the OIDC authorize flow in a system browser/custom tab, and the browser will handle cookies + antiforgery correctly.

• If you still want to allow posting to /Account/Login without antiforgery (not recommended), do it specifically for that Razor Page by overriding the login page model and suppressing antiforgery validation.

Solution

1. Keep ABP antiforgery enabled (recommended) and don’t call /Account/Login from the mobile app

• For Flutter/Maui AppAuth you should use:
  • /connect/authorize (system browser)
  • /connect/token (back-channel)
• Do not automate a form POST to /Account/Login from the app. That endpoint is designed for interactive browser login.

2. If you must disable antiforgery for /Account/Login, override the Razor Page and ignore antiforgery

• In your *.HttpApi.Host (or *.Web) project, create:

Pages/Account/Login.cshtml.cs

using Microsoft.AspNetCore.Mvc;
using Volo.Abp.Account.Web.Pages.Account;

namespace MyCompany.MyApp.HttpApi.Host.Pages.Account;

[IgnoreAntiforgeryToken] // disables Razor Pages antiforgery validation for this page
public class LoginModel : Volo.Abp.Account.Web.Pages.Account.LoginModel
{
    public LoginModel(
        Microsoft.AspNetCore.Authentication.IAuthenticationSchemeProvider schemeProvider,
        Microsoft.Extensions.Options.IOptions<Volo.Abp.Account.Web.AbpAccountOptions> accountOptions,
        Microsoft.Extensions.Options.IOptions<Microsoft.AspNetCore.Identity.IdentityOptions> identityOptions,
        Volo.Abp.Identity.IdentityDynamicClaimsPrincipalContributorCache contributorCache)
        : base(schemeProvider, accountOptions, identityOptions, contributorCache)
    {
    }
}

Pages/Account/Login.cshtml

• Create Pages/Account/Login.cshtml to override the UI (you can copy the original ABP login page markup from the Account module as described in ABP’s “customize login page” approach). The key part for antiforgery is the Login.cshtml.cs with [IgnoreAntiforgeryToken].

3. Remove your attempt to remove AutoValidateAntiforgeryTokenAttribute from MvcOptions

• That code targets MVC filters/attributes and won’t reliably remove the Razor Pages antiforgery filter that’s actually rejecting /Account/Login.

Notes (important for your symptom)

• ABP’s antiforgery system already bypasses validation for non-browser clients, but your failing request is to a Razor Page login endpoint, which is a browser/cookie flow and therefore expects antiforgery.
• If your mobile HTTP client is carrying cookies (or behaving like a browser), you can also trigger antiforgery expectations in some flows. But again: mobile should not be posting to /Account/Login in the first place for OIDC.

• In ABP MVC, the “Back to my account” button is shown only if the current principal contains the impersonation claim (i.e., ICurrentUser.FindImpersonatorUserId() != null). So the fastest way to debug is to verify whether impersonation is still active (claims/cookies) and whether the toolbar item is still being contributed.

1) Verify impersonation is actually active (claim exists)

1. While impersonating, open your page and inspect the authenticated user’s claims (e.g., put a breakpoint / temporary log in any MVC action):
   • Check CurrentUser.FindImpersonatorUserId() is NOT null.
2. If it’s null, the “back” button will not render. In that case, impersonation may still “look like it worked” (you’re logged in as the user) but the impersonator info wasn’t persisted (usually due to cookies/auth pipeline changes, custom account controller, reverse proxy cookie issues, etc.).

2) Ensure the UI part (toolbar contribution) exists in your app

For MVC, the button is not “magic”; it comes from the impersonation UI integration. If you customized your toolbar/layout/theme, you may have removed the contributor/view component that renders it.

Make sure you followed the MVC impersonation UI setup:

• Your Web module depends on the impersonation web module.
• Your toolbar includes an item (often via a toolbar contributor) that conditionally adds the button when FindImpersonatorUserId() != null.
• The endpoint POST ~/Account/BackToImpersonator exists (it’s the action the button posts to).

If you’ve overridden AccountController, confirm it still inherits from the impersonation-enabled base controller as required by the docs.

3) Quick isolation test: add the button manually

To prove it’s only a UI/toolbar problem (not claims), temporarily add this to your main layout (or a toolbar area) and test while impersonating:

@using Volo.Abp.Account.Localization
@using Microsoft.AspNetCore.Mvc.Localization
@inject IHtmlLocalizer<AccountResource> L

<form method="post" data-ajaxForm="false" action="~/Account/BackToImpersonator">
    @Html.AntiForgeryToken()
    <button type="submit" class="btn btn-link text-danger">
        @L["BackToImpersonator"]
    </button>
</form>

• If this appears and works, your problem is toolbar contributor / theme component not being executed or not rendering.
• If it posts but fails, then it’s not a rendering problem; check the action route and auth cookies/claims.

4) Common real cause: theme/mobile toolbar placement

There is a known case where the button is not visible depending on responsive/mobile toolbar placement (especially with LeptonX). In older versions it was fixed by upgrading (example reported/fixed in later versions for mobile view). Even on desktop, if your theme moved the user menu into a different place, the button may now be under the username menu instead of the top bar.

5) Confirm you didn’t restrict the toolbar contributor to a different toolbar

If you have custom IToolbarContributor code, ensure it’s contributing to the toolbar your layout uses (e.g., StandardToolbars.Main). A wrong toolbar name check can prevent the item from being added.

• Your external provider flow is actually succeeding and ABP is posting to /Account/Register?isExternalLogin=True to auto-create/link the user.
• The HTTP 400 you see is caused by ABP’s antiforgery validation on the error page pipeline, with this key log line:
  The provided antiforgery token was meant for a different claims-based user than the current user.
• In your log, the real breaking exception is not ABP but your custom code running right after the user is created:
  System.Collections.Generic.KeyNotFoundException: The given key 'IsSeeding' was not present in the dictionary.
  in Cns.Cloud.Apps.Users.UserCreatedEventHandler.HandleEventAsync(...).

So you have two issues:

1. Your UserCreatedEventHandler throws, which breaks the request (this is the primary failure).
2. The antiforgery warning/400 is a side-effect of the pipeline ending up on /Error?httpStatusCode=400 with a changed user context.

Fix (definitive)

1. Fix your event handler to not assume IsSeeding exists (use TryGetValue / ContainsKey, or provide a default). Example pattern:

public Task HandleEventAsync(EntityCreatedEto<IdentityUserEto> eventData)
{
    // Example: if you stored extra properties somewhere, never index directly
    // var isSeeding = dict["IsSeeding"]; // <- unsafe

    var isSeeding = false;
    if (eventData.Properties != null &&
        eventData.Properties.TryGetValue("IsSeeding", out var value) &&
        value is bool b)
    {
        isSeeding = b;
    }

    if (isSeeding)
    {
        return Task.CompletedTask;
    }

    // normal logic...
    return Task.CompletedTask;
}

(Adapt to your actual dictionary/object; the key point is don’t index with [...] unless you’re 100% sure it’s there.)

2. After fixing that exception, the external-login-first-time flow should complete without redirecting into an error path, and the antiforgery 400 should disappear.

Notes (what ABP is doing)

• ABP’s Account module can register external users on first login (that’s why /Account/Register?isExternalLogin=True appears).
• If you are using OpenIdConnect/AzureAD, make sure your provider configuration includes correct claim mappings/scopes (especially email) as described in the ABP article below.

• ABP’s built-in Emailing settings UI (Setting Management → Emailing) is designed for SMTP settings. There is no native tenant-level OAuth2 UI for the email sender in ABP 10.0.
• The recommended/working approach is to make email sending tenant-aware by:
  1. Storing OAuth configuration per tenant (via Setting Management or your own entity),
  2. Replacing IEmailSender with your own implementation that reads the current tenant’s configuration and sends using OAuth (e.g., Microsoft Graph, Gmail API, or SMTP with OAuth2 via MailKit if that’s your provider).

1) Store per-tenant OAuth settings (Setting Management)

Define your own setting names and register them with a SettingDefinitionProvider. ABP settings are automatically resolved per-tenant.

public static class TenantEmailOAuthSettings
{
    private const string Prefix = "MyApp.Email.OAuth";

    public const string Provider = Prefix + ".Provider";           // e.g. "MicrosoftGraph", "Gmail"
    public const string TenantId = Prefix + ".TenantId";
    public const string ClientId = Prefix + ".ClientId";
    public const string ClientSecret = Prefix + ".ClientSecret";
    public const string FromAddress = Prefix + ".FromAddress";
    public const string FromDisplayName = Prefix + ".FromDisplayName";
}

Then, create a custom settings UI page (Blazor Server) similar to how custom setting pages are added (same technique as “white labeling” examples: define settings + implement an app service using ISettingManager + add a UI page/group).

2) Replace IEmailSender with a tenant-aware OAuth sender

Implement IEmailSender and read settings using ISettingProvider (which resolves values in the context of the current tenant).

using System.Net.Mail;
using Volo.Abp.DependencyInjection;
using Volo.Abp.Emailing;
using Volo.Abp.Settings;

public class TenantOAuthEmailSender : IEmailSender, ITransientDependency
{
    private readonly ISettingProvider _settingProvider;

    public TenantOAuthEmailSender(ISettingProvider settingProvider)
    {
        _settingProvider = settingProvider;
    }

    public async Task SendAsync(MailMessage mail, bool normalize = true)
    {
        // Read per-tenant OAuth configuration
        var provider = await _settingProvider.GetOrNullAsync(TenantEmailOAuthSettings.Provider);
        var clientId = await _settingProvider.GetOrNullAsync(TenantEmailOAuthSettings.ClientId);
        var clientSecret = await _settingProvider.GetOrNullAsync(TenantEmailOAuthSettings.ClientSecret);

        // Use these to send via your chosen OAuth provider (Graph/Gmail/etc.)
        // (Implementation depends on provider; this is where you call Graph API, etc.)
        throw new NotImplementedException();
    }

    public Task SendAsync(string to, string subject, string body, bool isBodyHtml = true)
        => SendAsync(new MailMessage { Subject = subject, Body = body, IsBodyHtml = isBodyHtml, To = { to } });

    public Task SendAsync(string from, string to, string subject, string body, bool isBodyHtml = true)
        => SendAsync(new MailMessage(from, to, subject, body) { IsBodyHtml = isBodyHtml });

    public Task QueueAsync(string to, string subject, string body, bool isBodyHtml = true)
        => SendAsync(to, subject, body, isBodyHtml); // or integrate with background jobs
}

Register it by replacing ABP’s default email sender:

using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.DependencyInjection.Extensions;
using Volo.Abp.Modularity;

public class MyAppEmailModule : AbpModule
{
    public override void ConfigureServices(ServiceConfigurationContext context)
    {
        context.Services.Replace(ServiceDescriptor.Transient<IEmailSender, TenantOAuthEmailSender>());
    }
}

3) Make the settings editable by tenants (ABP UI / SaaS)

If you want tenants to edit email-related settings themselves, ABP can gate this via tenant features (SaaS). In practice, you enable the relevant tenant feature in the SaaS tenant management screen (this is how built-in “Emailing” settings visibility is controlled).

4) If you need “OAuth + SMTP” specifically

ABP’s default UI won’t cover OAuth flows. You typically:

• Create your own page to capture client id/secret/tenant id and perform admin consent / token acquisition (provider-specific),
• Persist the resulting tokens/credentials per tenant,
• Use them in your IEmailSender implementation.

• changePasswordToken is not an OpenIddict/OpenID Connect token type and there is no built-in OAuth/OIDC endpoint (like /connect/token) that “uses” it in ABP.

• In ABP, a “change password / reset password token” is an ASP.NET Core Identity user token (generated by UserManager.GeneratePasswordResetTokenAsync(...) / related APIs) and it must be consumed by an ABP Account endpoint (HTTP API) that performs the password change/reset (not the OpenIddict token endpoint).

• So the correct flow is typically:

  1. Call an account endpoint to initiate the reset/forgot-password flow (server generates token + sends email/link, or returns token depending on your customization).
  2. Call an account endpoint to submit the token + new password (server verifies the token via Identity and changes the password).
  3. After password is changed, obtain an access token normally via OpenIddict (/connect/token with password / authorization_code / etc.).

• If your goal is: “I want to exchange changePasswordToken for an access token at /connect/token”, that’s not supported by default. You would need to implement a custom OpenIddict extension grant (ITokenExtensionGrant) and validate your token yourself, then issue an access token.

  Minimal outline (ABP’s OpenIddict extension grant mechanism):

  • Register your custom grant name in OpenIddictServerOptions.GrantTypes
  • Register an ITokenExtensionGrant implementation in AbpOpenIddictExtensionGrantsOptions
  • In HandleAsync(...), validate the incoming token and return SignInResult to generate a token response.
