Commands continue to use the default write DbContext/connection. This isolates read traffic to replicas and protects OLTP writes.
Reporting architecture
public class PrepareDailyLedgerJobArgs { public DateOnly Date { get; set; } }
public class PrepareDailyLedgerJob : AsyncBackgroundJob<PrepareDailyLedgerJobArgs>
{
private readonly IReportProjectionService _projection;
public PrepareDailyLedgerJob(IReportProjectionService projection) { _projection = projection; }
public override async Task ExecuteAsync(PrepareDailyLedgerJobArgs args)
{
await _projection.BuildDailyLedgerAsync(args.Date); // read from OLTP, write into reporting store
}
}
Use the Event Bus to publish domain events on transaction commit; a subscriber projects them into a reporting model (append-only or summarized aggregates). This keeps OLTP queries simple and reporting isolated.
Data stores: keep OLTP in SQL Server; create a separate reporting database (same SQL Server or separate instance). Point reporting UI to the reporting DB or read-only context.
Caching strategy (financial data)
public class CurrencyRatesCacheItem
{
public DateTime AsOf { get; set; }
public Dictionary<string, decimal> Rates { get; set; } = new();
}
public class CurrencyRateAppService : ApplicationService
{
private readonly IDistributedCache<CurrencyRatesCacheItem> _cache;
public CurrencyRateAppService(IDistributedCache<CurrencyRatesCacheItem> cache) { _cache = cache; }
[UnitOfWork(IsTransactional = false)]
public virtual async Task<CurrencyRatesCacheItem> GetRatesAsync()
{
return await _cache.GetOrAddAsync(
"CurrencyRates:Current",
async () => await LoadRatesAsync(),
() => new DistributedCacheEntryOptions { AbsoluteExpirationRelativeToNow = TimeSpan.FromMinutes(5) }
);
}
}
public class TransactionAppService : ApplicationService
{
private readonly IDistributedCache<AccountSummaryDto> _cache;
private readonly IRepository<Transaction, Guid> _txRepo;
private readonly IUnitOfWorkManager _uowManager;
public async Task PostAsync(CreateTransactionDto input)
{
await _txRepo.InsertAsync(Map(input));
await CurrentUnitOfWork.SaveChangesAsync();
_uowManager.Current.OnCompleted(async () =>
{
await _cache.RemoveAsync($"AccountSummary:{input.AccountId}");
});
}
}
Avoid caching mutable balances unless you can tolerate staleness for a short TTL; otherwise, cache reference data and computed report snapshots.

[DependsOn(
typeof(AbpHttpClientIdentityModelModule), // needed if you authenticate with OpenID Connect/IdentityModel
typeof(YourAppHttpApiClientModule) // from the Tiered app
)]
public class YourSingleWebModule : AbpModule
{
public override void ConfigureServices(ServiceConfigurationContext context)

}
}

}
}
- If your HttpApi.Client module uses a custom remote service name, configure that key instead of Default. The key must match the remote service name used during proxy registration.

The error NETSDK1004: project.assets.json not found indicates NuGet packages were not restored before ABP Studio tried to run EF Core’s Add-Migration during Database synchronization. Also, the path shows .NET SDK 10.0.100 (preview/next gen) which is not yet supported by ABP Studio templates. Do the following once, then retry Database synchronization from ABP Studio.
A) Ensure supported .NET SDKs are installed and selected
B) Restore and build the solution before database sync
C) Verify EF Core tools work against the DbContext project
D) Run ABP Studio from the solution root
E) If the task still fails in Studio

Root cause
What you can do
Preferred: Switch to an implementation that supports per-job queues
Or, keep MySQL but disable ABP’s Hangfire background workers and use a different background worker implementation in ABP
Example module setup:
[DependsOn(
typeof(AbpBackgroundWorkersQuartzModule), // run ABP workers via Quartz
typeof(AbpBackgroundJobsModule) // keep generic jobs; add Hangfire only if you need it
// typeof(AbpBackgroundJobsHangfireModule) // include only if you will use Hangfire for IBackgroundJobManager
)]
public class MyProjectDomainModule : AbpModule
{
public override void PreConfigureServices(ServiceConfigurationContext context)
{
// Configure Quartz persistence (e.g., MySQL/PostgreSQL/SQL Server)
PreConfigure<AbpQuartzOptions>(options =>
{
options.Configurator = cfg =>
{
cfg.UsePersistentStore(store =>
{
store.UseProperties = true;
store.UseJsonSerializer();
store.UseMySql("Your MySQL connection string"); // or other provider
});
};
});
}
}
- In your web host, remove AddHangfireServer if you don’t need Hangfire workers at all, or keep it only for background jobs that don’t specify per-job queue options in a way MySQL storage rejects.
- ABP’s internal workers (Identity session cleanup, token cleanup, audit log cleanup, etc.) will run under Quartz and won’t call Hangfire. That sidesteps the Hangfire/MySQL queue limitation.

A) MVC / Razor Pages (ABP Identity module) Goal examples:
Code outline:
ObjectExtensionManager.Instance.Modules().ConfigureIdentity(identity =>
{
identity.ConfigureUser(user =>
{
user.AddOrUpdateProperty<string>("Code");
user.AddOrUpdateProperty<string>("Address");
user.AddOrUpdateProperty<string>("Manager");
});
});
ObjectExtensionManager.Instance
.MapEfCoreProperty<IdentityUser, string>("Code")
.MapEfCoreProperty<IdentityUser, string>("Address")
.MapEfCoreProperty<IdentityUser, string>("Manager");
public class YourAppContractsModule : AbpModule
{
public override void PostConfigureServices(ServiceConfigurationContext context)
{
ModuleExtensionConfigurationHelper.ApplyEntityConfigurationToApi(
IdentityModuleExtensionConsts.ModuleName,
IdentityModuleExtensionConsts.EntityNames.User,
getApiTypes: new[] { typeof(IdentityUserDto) },
createApiTypes: new[] { typeof(IdentityUserCreateDto) },
updateApiTypes: new[] { typeof(IdentityUserUpdateDto) }
);
}
}
This makes the Identity Users CRUD automatically show your new properties on the list and modal when possible.
Note:
B) Blazor (Blazor Server/WebAssembly) Goal examples:
Approach: Extend entity actions and navigate to your page
[ExposeServices(typeof(UserManagement))]
[Dependency(ReplaceServices = true)]
public class CustomizedUserManagement : UserManagement
{
protected override async ValueTask SetEntityActionsAsync()
{
await base.SetEntityActionsAsync();
var advancedEdit = new EntityAction
{
Text = "Advanced edit",
Clicked = data =>
{
// Navigate to your custom component/page with user Id in route/query.
NavigationManager.NavigateTo($"/users/advanced-edit/{data.Id}");
return Task.CompletedTask;
}
};
EntityActions.Get<UserManagement>().Add(advancedEdit);
}
}
C) Angular (Manage Profile or Users UI customization)
import { eAccountManageProfileTabNames, ManageProfileTabsService } from '@volo/abp.ng.account/public/config';
export class AppComponent implements OnInit {
constructor(private manageProfileTabs: ManageProfileTabsService) {}
ngOnInit() {
this.manageProfileTabs.patch(eAccountManageProfileTabNames.PersonalInfo, {
component: CustomPersonalSettingsComponent,
});
}
}
ModuleExtensionConfigurationHelper.ApplyEntityConfigurationToApi(
IdentityModuleExtensionConsts.ModuleName,
IdentityModuleExtensionConsts.EntityNames.User,
getApiTypes: new[] { typeof(IdentityUserDto), typeof(ProfileDto) },
createApiTypes: new[] { typeof(IdentityUserCreateDto) },
updateApiTypes: new[] { typeof(IdentityUserUpdateDto), typeof(UpdateProfileDto) }
);
D) Profile Management page (MVC) contributions instead of replacing everything
public class MyProfileManagementPageContributor : IProfileManagementPageContributor
{
public Task ConfigureAsync(ProfileManagementPageCreationContext context)
{
context.Groups.Add(new ProfileManagementPageGroup(
"my-account-profile",
"My account profile",
typeof(MyPictureManagementGroupViewComponent)
));
return Task.CompletedTask;
}
}
public class MyModule : AbpModule
{
public override void ConfigureServices(ServiceConfigurationContext context)
{
Configure<ProfileManagementPageOptions>(options =>
{
options.Contributors.Add(new MyProfileManagementPageContributor());
});
}
}
E) When moving from modal to page-based editing (MVC)

@using Microsoft.AspNetCore.Authorization
@using Volo.Abp.DependencyInjection
@using Volo.Abp.Identity
@using Volo.Abp.Identity.Blazor.Pages.Identity
@attribute [Authorize(IdentityPermissions.Users.Default)]
@attribute [ExposeServices(typeof(UserManagement))]
@attribute [Dependency(ReplaceServices = true)]
@inherits UserManagement
<!-- Your customized Users UI goes here -->
Example: override Roles page
@using Microsoft.AspNetCore.Authorization
@using Volo.Abp.DependencyInjection
@using Volo.Abp.Identity
@using Volo.Abp.Identity.Blazor.Pages.Identity
@attribute [Authorize(IdentityPermissions.Roles.Default)]
@attribute [ExposeServices(typeof(RoleManagement))]
@attribute [Dependency(ReplaceServices = true)]
@inherits RoleManagement
<!-- Your customized Roles UI goes here -->
You can fully redesign the UI (e.g., use MudBlazor, change dialogs to full-page EditForm, etc.) while reusing the base logic by calling the protected members like AppService, MapToCreateInput, MapToEditingEntity, GetListInput, and permission properties.
public class UsersPageToolbarContributor : IPageToolbarContributor
{
public Task ConfigureAsync(PageToolbarContributionContext context)
{
if (context.PageName == IdentityPageNames.Users)
{
context.Toolbar.Items.Add(new PageToolbarItem
{
Text = "Import users",
Icon = "upload",
OnClick = async () =>
{
// your import logic
}
});
}
return Task.CompletedTask;
}
}
Register contributor in your module:
Configure<PageToolbarOptions>(opts =>
{
opts.Contributors.Add(new UsersPageToolbarContributor());
});
public override void PostConfigureServices(ServiceConfigurationContext context)
{
ModuleExtensionConfigurationHelper.ApplyEntityConfigurationToApi(
IdentityModuleExtensionConsts.ModuleName,
IdentityModuleExtensionConsts.EntityNames.User,
getApiTypes: new[] { typeof(IdentityUserDto), typeof(ProfileDto) },
createApiTypes: new[] { typeof(IdentityUserCreateDto) },
updateApiTypes: new[] { typeof(IdentityUserUpdateDto), typeof(UpdateProfileDto) }
);
}
[DependsOn(typeof(Volo.Abp.Identity.Pro.Blazor.AbpIdentityProBlazorModule))]
public class YourBlazorModule : AbpModule
{
public override void ConfigureServices(ServiceConfigurationContext context)
{
// your customizations
}
}
[ExposeServices(typeof(TheProBaseComponentYouOverride))]
[Dependency(ReplaceServices = true)]
You can still use PageToolbar and EntityAction extensions for Pro pages.

Root cause
Fix: force the correct content type on the action and let Swagger describe it properly
Example:
using Microsoft.AspNetCore.Mvc;
using Volo.Abp.Content;
public class CreateFileInputWithStream
{
public string Name { get; set; }
public IRemoteStreamContent File { get; set; }
public ExtraPropertyDictionary ExtraProperties { get; set; }
}
[ApiController]
[Route("api/app/organization-attachment")]
public class OrganizationAttachmentController : ControllerBase
{
[HttpPost]
[Consumes("multipart/form-data")]
public async Task<AttachmentDto> CreateAsync(
[FromQuery] Guid attachmentTypeId,
[FromQuery] Guid entityId,
[FromForm] CreateFileInputWithStream inputWithStream,
[FromQuery] bool replaceByAttachmentType = false,
[FromQuery] bool autoSave = false)
{
// call your service method here
// return await _appService.CreateAsync(...);
throw new NotImplementedException();
}
}
Notes:
[Consumes("multipart/form-data")]
public virtual Task<TAttachmentDto> CreateAsync(
Guid attachmentTypeId,
TEntityKey entityId,
[FromForm] CreateFileInputWithStream inputWithStream,
bool replaceByAttachmentType = false,
bool autoSave = false)
{ ... }
After adding Consumes + FromForm, re-run and check the Blazor Server Swagger. It should now show a multipart/form-data body with a binary File field, matching your HttpApi.Host/API swagger.
Ensure the WASM static proxy posts FormData
// In Blazor WASM
var form = new MultipartFormDataContent();
form.Add(new StringContent(attachmentTypeId.ToString()), "attachmentTypeId");
form.Add(new StringContent(entityId.ToString()), "entityId");
form.Add(new StringContent(input.Name), "inputWithStream.Name");
form.Add(new StreamContent(fileStream) { Headers = { ContentType = new MediaTypeHeaderValue(fileContentType) }}, "inputWithStream.File", fileName);
// plus ExtraProperties if needed
Prefer using the generated C# static proxy method for the service interface; once Swagger describes multipart/form-data correctly, the proxy will send the right content type and 415 will disappear.
If the Blazor Server host still shows the wrong content type

The Docs module reads only ElasticSearch:Url from IConfiguration in DefaultElasticClientProvider. To use credentials, extend DocsElasticSearchOptions.Authenticate to apply BasicAuthentication (or your desired auth) to the Elastic client settings, and bind username/password from configuration.
Add these to appsettings.json: { "ElasticSearch": { "Url": "https://elasticsearch-sample-es-http.elastic-system.svc.cluster.local:9200", "UserName": "myuser", "Password": "mypassword" } }
Create a custom IElasticClientProvider and replace the default one: using Microsoft.Extensions.Configuration; using Microsoft.Extensions.DependencyInjection; using Microsoft.Extensions.Options; using Nest; using System; using Volo.Abp.DependencyInjection; using Volo.Docs.Documents.FullSearch.Elastic;
public class BasicAuthElasticClientProvider : IElasticClientProvider, ISingletonDependency { private readonly DocsElasticSearchOptions _options; private readonly IConfiguration _configuration;
public BasicAuthElasticClientProvider(IOptions<DocsElasticSearchOptions> options, IConfiguration configuration)
{
_options = options.Value;
_configuration = configuration;
}
public IElasticClient GetClient()
{
var node = new Uri(_configuration["ElasticSearch:Url"]);
var settings = new ConnectionSettings(node)
.DefaultIndex(_options.IndexName);
// Apply Basic authentication using configuration
var username = _configuration["ElasticSearch:UserName"];
var password = _configuration["ElasticSearch:Password"];
if (!string.IsNullOrWhiteSpace(username) && !string.IsNullOrWhiteSpace(password))
{
settings = settings.BasicAuthentication(username, password);
}
// If you already use Options.Authenticate, keep it to allow further customization
return new ElasticClient(_options.Authenticate(settings));
}
}
Register your replacement in your module: using Microsoft.Extensions.DependencyInjection; using Volo.Abp.Modularity; using Volo.Docs.Documents.FullSearch.Elastic;
[DependsOn(typeof(VoloDocsDomainModule))] public class YourModule : AbpModule { public override void ConfigureServices(ServiceConfigurationContext context) { context.Services.AddSingleton<IElasticClientProvider, BasicAuthElasticClientProvider>(); } }

Current behavior (ABP v9.3.3): Volo.Abp.AzureServiceBus’s ConnectionPool expects a connection string and throws when it’s missing. This prevents using Managed Identity out-of-the-box.
Workable approach today (non-breaking, recommended):
Example:
using Azure.Core;
using Azure.Identity;
using Azure.Messaging.ServiceBus;
using Microsoft.Extensions.Options;
using Volo.Abp;
using Volo.Abp.AzureServiceBus;
using Volo.Abp.Modularity;
[DependsOn(typeof(AbpAzureServiceBusModule))]
public class MyAzureServiceBusMiModule : AbpModule
{
public override void ConfigureServices(ServiceConfigurationContext context)
{
// Configure your namespace in options
Configure<AbpAzureServiceBusOptions>(opt =>
{
opt.Namespace = "<your-namespace>"; // e.g. mybusns
// You can still set TopicName/SubscriptionName if you use ABP’s distributed event bus
});
context.Services.AddSingleton<TokenCredential, DefaultAzureCredential>();
// Replace ServiceBusClient registration to use MI instead of connection string
context.Services.AddSingleton<ServiceBusClient>(sp =>
{
var options = sp.GetRequiredService<IOptions<AbpAzureServiceBusOptions>>().Value;
var credential = sp.GetRequiredService<TokenCredential>();
// Fully qualified namespace: "<namespace>.servicebus.windows.net"
var fqn = $"{options.Namespace}.servicebus.windows.net";
return new ServiceBusClient(fqn, credential);
});
// Optionally: if you use sender/processor factories relying on ConnectionPool,
// you can replace IConnectionPool with your own implementation.
context.Services.Replace(ServiceDescriptor.Singleton<IConnectionPool, ManagedIdentityConnectionPool>());
}
}
// Example minimal pool that creates clients using MI when no connection string is present
public class ManagedIdentityConnectionPool : IConnectionPool
{
private readonly ConcurrentDictionary<string, ServiceBusClient> _clients = new();
private readonly TokenCredential _credential;
public ManagedIdentityConnectionPool(TokenCredential credential)
{
_credential = credential;
}
public ServiceBusClient Get(string fullyQualifiedNamespace, string? connectionString = null)
{
// Prefer connection string when provided, otherwise use MI
return _clients.GetOrAdd(fullyQualifiedNamespace, ns =>
{
if (!string.IsNullOrWhiteSpace(connectionString))
{
return new ServiceBusClient(connectionString);
}
return new ServiceBusClient(ns, _credential);
});
}
}
Notes:
Ensure the managed identity (system-assigned or user-assigned) has at least Azure Service Bus Data Sender/Receiver roles on the namespace.
For ABP Distributed Event Bus, keep using AbpAzureServiceBusOptions for entity names (topic/subscription). Only authentication changes.
