# ABP Platform 10.0 RC Has Been Released We are happy to release [ABP](https://abp.io) version **10.0 RC** (Release Candidate). This blog post introduces the new features and important changes in this new version. Try this version and provide feedback for a more stable version of ABP v10.0! Thanks to you in advance. ## Get Started with the 10.0 RC You can check the [Get Started page](https://abp.io/get-started) to see how to get started with ABP. You can either download [ABP Studio](https://abp.io/get-started#abp-studio-tab) (**recommended**, if you prefer a user-friendly GUI application - desktop application) or use the [ABP CLI](https://abp.io/docs/latest/cli). By default, ABP Studio uses stable versions to create solutions. Therefore, if you want to create a solution with a preview version, first you need to create a solution and then switch your solution to the preview version from the ABP Studio UI: ![studio-switch-to-preview.png](studio-switch-to-preview.png) ## Migration Guide There are a few breaking changes in this version that may affect your application. Please read the migration guide carefully, if you are upgrading from v9.3 or earlier: [ABP Version 10.0 Migration Guide](https://abp.io/docs/10.0/release-info/migration-guides/abp-10-0). ## What's New with ABP v10.0? In this section, I will introduce some major features released in this version. Here is a brief list of titles explained in the next sections: * Upgraded to .NET 10.0 * Upgraded to Blazorise 1.8.2 * New Module: **Workflow (Elsa)** * New Object Mapper: **Mapperly** * Localization: Nested object support in JSON files * Support EF Core Shared Entity Types on Repositories * Add failure retry policy to InboxProcessor * Migrate to New Esbuild-based Angular Builder * Angular SSR support ### Upgraded to .NET 10.0 We've upgraded ABP to .NET 10.0, so you need to move your solutions to .NET 10.0 if you want to use ABP 10.0. > Since the stable version of .NET 10 hasn't been released yet, we upgraded ABP to .NET v10.0-rc.1. Stable NET 10 is scheduled to launch as a **Long-Term Support (LTS)** release during .NET Conf 2025, which takes place November 11-13, 2025. We'll update the ABP Platform to the .NET 10 as soon as possible official .NET 10 release is completed. ### Upgraded to Blazorise v1.8.2 Upgraded the [Blazorise](https://blazorise.com/) library to v1.8.2 for Blazor UI. If you are upgrading your project to v10.0 RC, please ensure that all the Blazorise-related packages are using v1.8.2 in your application. Otherwise, you might get errors due to incompatible versions. > See [#23717](https://github.com/abpframework/abp/issues/23717) for the updated NuGet packages. ### New Module: **Workflow (Elsa)** ABP now ships a Workflow module that integrates [Elsa Workflows](https://github.com/elsa-workflows/elsa-core) to build visual, long-running, event-driven workflows in your ABP solutions (monolith or microservices). It provides seamless integration with ABP authentication/authorization, distributed event bus, persistence, background processing and includes support for hybrid UIs via Elsa Studio. For a hands-on reference showcasing an end-to-end order/payment workflow across services, see the sample: [Elsa Workflows - Sample Workflow Demo](https://abp.io/docs/10.0/samples/elsa-workflows-demo). For capabilities, installation and configuration details (activities, storage, hosting, dashboard), see the module docs: [Workflow (Elsa) module](https://abp.io/docs/10.0/modules/elsa-pro). ![Workflow (Elsa) module](./elsa-workflow-instances.png) ### New Object Mapper: **Mapperly** ABP modules now use Mapperly as the default object-to-object mapper. Mapperly is a compile-time, source generator–based mapper that removes runtime reflection and offers better performance with simpler maintenance. For background and implementation details, see the planning issue and the PR: [Switch to another object mapping library](https://github.com/abpframework/abp/issues/23243) and [Use Mapperly to replace AutoMapper in all modules](https://github.com/abpframework/abp/pull/23277). The `Volo.Abp.AutoMapper` package remains available for backward compatibility. You can keep using AutoMapper in your solutions, but you are responsible for obtaining and managing its license if needed. For upgrade guidance and practical steps, follow the migration guide: [AutoMapper to Mapperly](https://abp.io/docs/10.0/release-info/migration-guides/AutoMapper-To-Mapperly). ### Localization: Nested object support in JSON files ABP now supports nested objects (and arrays) in JSON localization files, allowing you to organize translations hierarchically and access them using the double underscore (`__`) separator. This improves maintainability for larger resource files and aligns lookups with familiar key paths. > See the PR for details: [feat(l8n): add support for nested objects in localization files](https://github.com/abpframework/abp/pull/23701). **Declaration (nested objects)**: ```json { "culture": "en", "texts": { "MyNestedTranslation": { "SomeKey": "Some nested value", "SomeOtherKey": "Some other nested value" } } } ``` **Usage**: ```csharp L["MyNestedTranslation__SomeKey"]; L["MyNestedTranslation__SomeOtherKey"]; ``` **Declaration (arrays)**: ```json { "culture": "en", "texts": { "Menu": { "Items": ["Home", "About", "Contact"] } } } ``` **Usage**: ```csharp L["Menu__Items__0"]; // Home L["Menu__Items__2"]; // Contact ``` ### Support EF Core Shared Entity Types on Repositories ABP repositories now support EF Core **shared-type entity** types by allowing a custom entity name to be set on a repository before performing operations. Internally, this uses EF Core's `DbContext.Set(string name)` to target the correct `DbSet`/table for the same CLR type, enabling scenarios like per-tenant tables, archives, or partitioning, and you can switch the target at runtime. See the PR: [Support EF Core Shared Entity Types on Repositories](https://github.com/abpframework/abp/pull/23588) and the EF Core documentation on [shared-type entity types](https://learn.microsoft.com/en-us/ef/core/modeling/entity-types?tabs=data-annotations#shared-type-entity-types). **Example**: ```csharp // Set the shared entity name so repository operations target that table var repo = serviceProvider.GetRequiredService>(); repo.SetCustomEntityName("MyEntity_TenantA"); var list = await repo.GetListAsync(); // Switch to another shared name later on the same instance repo.SetCustomEntityName("MyEntity_Archive"); await repo.InsertAsync(new MyEntity { /* ... */ }); ``` ### Add failure retry policy to InboxProcessor `InboxProcessor` now supports configurable failure handling strategies per event: **Retry** (default; reprocess in the next cycle), **RetryLater** (skip the failing event and retry it later with exponential backoff; the backoff factor and maximum retries are configurable), and **Discard** (drop the failing event). This prevents a single failing handler from blocking subsequent events and improves resiliency. > **Note**: This is a breaking change because `IncomingEvent` entity properties were updated. See the PR for details: [Add failure retry policy to InboxProcessor](https://github.com/abpframework/abp/pull/23563). ### Migrate to New Esbuild-based Angular Builder We've migrated ABP Angular templates and packages to Angular's new esbuild-based build system (introduced in Angular 17+ and fully supported in Angular 20) to deliver faster builds, modern ESM support, built-in SSR/prerender capabilities, and a better development experience. This change is non-breaking for existing apps. See the tracking issue and PR: [Angular - Migrate to New Esbuild-based Angular Builder](https://github.com/abpframework/abp/issues/23242), [feat: Update Angular templates to Angular 20 new build system](https://github.com/abpframework/abp/pull/23363). **Key updates in templates/config**: - Builder switched from `@angular-devkit/build-angular:browser` to `@angular-devkit/build-angular:application`. - `main` option replaced by `browser`; `polyfills` moved to array form. - TypeScript updated to `es2020` with `esModuleInterop: true`; module target `esnext`. **More Angular updates**: - Unit tests have been updated for the new builder and configuration: [#23460](https://github.com/abpframework/abp/pull/23460). **Warnings**: - Constructor injections migrated to Angular's `inject()` function. If you extend a class and previously called `super(...)` with injected params, remove those parameters. See: [Angular inject() migration](https://angular.dev/reference/migrations/inject-function). - `provideLogo` and `withEnvironmentOptions` have moved from LeptonX packages to `@abp/ng.theme-shared`. - If you use the new application builder and have `tsconfig.json` path mappings that point into `node_modules`, remove those mappings and prefer symlinks instead. See a symlink reference: [Creating symbolic links](https://hostman.com/tutorials/creating-symbolic-links-in-linux/). ### Angular SSR support ABP Angular templates now support Server-Side Rendering (SSR) with the Angular Application Builder, enabling hybrid rendering (SSR + CSR) for improved first paint, SEO and perceived performance. This includes SSR-safe platform checks (no direct `window`/`location`/`localStorage`), OIDC auth compatibility via cookie-backed storage, and `TransferState` to prevent duplicate HTTP GETs during hydration. For implementation highlights and usage (including how to run the SSR dev server and the `transferStateInterceptor`), see the issue and PR: [Angular SSR](https://github.com/abpframework/abp/issues/23055), [Hybrid Rendering & Application Builder](https://github.com/abpframework/abp/pull/23416). > See Angular's official guide for details on hybrid rendering (prerender + SSR + CSR): [Angular SSR](https://angular.dev/guide/ssr) and on the builder migration: [Angular build system migration](https://angular.dev/tools/cli/build-system-migration). ## Community News ### Recent Events We recently hosted two sessions of ABP Community Talks: #### Community Talks 2025.06: Microservices with ABP Template The Easiest Way to Get Started with Microservices on .NET Using ABP Microservice Solution Template: a deep dive into ABP’s microservice template, showing how ABP Studio streamlines creating, running, and scaling distributed systems.
