This document describes ASP.NET Core integration for ASP.NET Boilerplate framework. ASP.NET Core integration is implemented in Abp.AspNetCore nuget package

    Migrating to ASP.NET Core?

    If you have an existing project and considering to migrate to ASP.NET Core, you can read our blog post for our experince on the migration.

    Startup Template

    You can create your project from startup template, which is a simple, empty web project but properly integrated and configured to work with ABP framework.


    Startup Class

    To integrate ABP to ASP.NET Core, we should make some changes in the Startup class as shown below:

    public class Startup
        public IServiceProvider ConfigureServices(IServiceCollection services)
            //Configure Abp and Dependency Injection. Should be called last.
            return services.AddAbp<MyProjectWebModule>(options =>
                //Configure Log4Net logging (optional)
                    f => f.UseLog4Net().WithConfig("log4net.config")
        public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
            //Initializes ABP framework and all modules. Should be called first.

    Module Configuration

    You can use startup configuration to configure AspNet Core Module (using Configuration.Modules.AbpAspNetCore() in PreInitialize of your module).


    Controllers can be any type of classes in ASP.NET Core. It's not restricted to classes derived from Controller class. By default, a class ends with Controller (like ProductController) is considered as MVC Controller. You can also add MVC's [Controller] attribute to any class to make it a controller. This is the way ASP.NET Core MVC is working. See ASP.NET Core documentation for more.

    If you will use web layer classes (like HttpContext) or return a view, it's better to inherit from AbpController (which is derived from MVC's Controller) class. But if you are creating an API controller just works with objects, you can consider to create a POCO controller class or you can use your application services as controllers as described below.

    Application Services as Controllers

    ASP.NET Boilerplate provides infrastructure to create application services. If you want to expose your application services to remote clients as controllers (as previously done using dynamic web api), you can easily do it by a simple configuration in PreInitialize method of your module. Example:

    Configuration.Modules.AbpAspNetCore().CreateControllersForAppServices(typeof(MyApplicationModule).Assembly, moduleName: 'app', useConventionalHttpVerbs: true);

    CreateControllersForAppServices method gets an assembly and converts all application services to MVC controllers in that assembly. You can use RemoteService attribute to enable/disable it for method or class level.

    When an application service is converted to MVC Controller, it's default route will be like /api/services/<module-name>/<service-name>/<method-name>. Example: If ProductAppService defines a Create method, it's URL will be /api/services/app/product/create (assumed that module name is 'app').

    If useConventionalHttpVerbs set to true (which is the default value), then HTTP verbs for service methods are determined by naming conventions:

    • Get: Used if method name starts with 'Get'.
    • Put: Used if method name starts with 'Put' or 'Update'.
    • Delete: Used if method name starts with 'Delete' or 'Remove'.
    • Post: Used if method name starts with 'Post', 'Create' or 'Insert'.
    • Patch: Used if method name starts with 'Patch'.
    • Otherwise, Post is used as default HTTP verb.

    You can use any ASP.NET Core attributes to change HTTP methods or routes of the actions (but surely, this requires to add reference to related ASP.NET Core package).

    Note: Previously, dynamic web api system was requiring to create service interfaces for application services. But this is not required for ASP.NET Core integration. Also, MVC attributes should be added to the service classes, even you have interfaces.


    ABP defines some pre-built filters for AspNet Core. All of them are added to all actions of all controllers by default.

    Authorization Filter

    AbpAuthorizationFilter is used to integrate to authorization system and feature system.

    • You can define AbpMvcAuthorize attribute for actions or controllers to check desired permissions before action execution.
    • You can define RequiresFeature attribute for actions or controllers to check desired features before action execution.
    • You can define AllowAnonymous (or AbpAllowAnonymous in application layer) attribute for actions or controllers to suppress authentication/authorization.

    Audit Action Filter

    AbpAuditActionFilter is used to integrate to audit logging system. It logs all requests to all actions by default (if auditing is not disabled). You can control audit logging using Audited and DisableAuditing attributes for actions and controllers.

    Validation Action Filter

    AbpValidationActionFilter is used to integrate to validation system and automatically validate all inputs of all actions. In addition to ABP's built-in validation & normalization, it also checks MVC's Model.IsValid property and throws validation exception if action inputs have any invalid value.

    You can control validation using EnableValidation and DisableValidation attributes for actions and controllers.

    Unit of Work Action Filter

    AbpUowActionFilter is used to integrate to Unit of Work system. It automatically begins a new unit of work before an action execution and completes unit of work after action exucition (if no exception is thrown).

    You can use UnitOfWork attribute to control behaviour of UOW for an action. You can also use startup configuration to change default unit of work attribute for all actions.

    Exception Filter

    AbpExceptionFilter is used to handle exceptions thrown from controller actions. It handles and logs exceptions and returns wrapped response to the client.

    • It only handles object results, not view results. So, actions returns any object, JsonResult or ObjectResult will be handled. Action returns a view or any other result type implements IActionsResult are not handled. It's suggested to use built-in UseExceptionHandler extension method defined in Microsoft.AspNetCore.Diagonistics package to handle view exceptions.
    • Exception handling and logging behaviour can be changed using WrapResult and DontWrapResult attributes for methods and classes.

    Result Filter

    AbpResultFilter is mainly used to wrap result action if action is successfully executed.

    • It only wraps results for JsonResult, ObjectResult and any object which does not implement IActionResult (and also their async versions). If your action is returning a view or any other type of result, it's not wrapped.
    • WrapResult and DontWrapResult attributes can be used for methods and classes to enable/disable wrapping.
    • You can use startup configuration to change default behaviour for result wrapping.
    Result Caching For Ajax Requests

    AbpResultFilter adds Cache-Control header (no-cache, no-store) to the response for AJAX Requests. Thus, it prevents browser caching of AJAX responses even for GET requests. This behaviour can be disabled by the configuration.

    Model Binders

    AbpDateTimeModelBinder is used to normalize DateTime (and Nullable<DateTime>) inputs using Clock.Normalize method.


    MVC Views can be inherited from AbpRazorPage to automatically inject most used infrastructure (LocalizationManager, PermissionChecker, SettingManager... etc.). It also has shortcut methods (like L(...) for localize texts). Startup template inherits it by default.

    Client Proxies

    ABP can automatically create javascript proxies for all MVC Controllers (not only application services). It's created for Application Services as Controllers (see the section above) by default. You can add [RemoteService] attribute to any MVC controller to create client proxy for it. Javascript proxies are dynamically generated on runtime. You need to add given script definition to your page:

    <script src="~/AbpServiceProxies/GetAll?type=jquery" type="text/javascript"></script>

    Currently, only JQuery proxies are generated. We can then call an MVC method with javascript as shown below:{
        name: 'My test product',
        price: 99

    Integration Testing

    Integration testing is fairly easy for ASP.NET Core and it's documented it's own web site in details. ABP follows this guide and provides AbpAspNetCoreIntegratedTestBase class in Abp.AspNetCore.TestBase package. It makes integration testing even easier.

    It's better to start by investigating integration tests in startup template to see it in action.
