How to Use MVC Controller and WebAPI Controller in same project

How to Use MVC Controller and WebAPI Controller in same project

In ASP.NET Core, it's possible to use both MVC controllers and Web API controllers in the same project. Here are the general steps to achieve this:

  • Create a new ASP.NET Core project using the appropriate template, such as the "ASP.NET Core Web Application" template.

  • In the project, create a new folder called "Controllers". This folder will contain both the MVC controllers and the API controllers.

  • Add a new MVC controller to the "Controllers" folder, using the "MVC Controller - Empty" template.

  • Add a new Web API controller to the "Controllers" folder, using the "API Controller - Empty" template.

  • In the "Startup.cs" file, configure the MVC middleware and the Web API middleware by adding the following lines of code to the "ConfigureServices" method:

services.AddMvc(); services.AddControllers();
  • In the "Startup.cs" file, add the following lines of code to the "Configure" method:
app.UseRouting(); app.UseEndpoints(endpoints => { endpoints.MapControllers(); });
  • In the MVC controller, define an action method that returns a view, and decorate it with the [HttpGet] attribute, like this:
[HttpGet] public IActionResult Index() { return View(); }
  • In the Web API controller, define an action method that returns data, and decorate it with the [HttpGet] attribute, like this:
[HttpGet] public IEnumerable<string> Get() { return new string[] { "value1", "value2" }; }
  • Run the project and navigate to the URL of the MVC action method to see the view, and navigate to the URL of the Web API action method to see the data.

Note that this is a basic example, and there are many other factors to consider when using both MVC and Web API in the same project, such as routing, authentication, and authorization. However, the steps above should provide a good starting point for getting started with both types of controllers in the same project.

Examples

  1. "MVC and WebAPI controllers in same project example"

    • Description: Learn how to integrate MVC and WebAPI controllers within the same ASP.NET MVC project for handling both traditional web pages and API endpoints.

    Code:

    // MVC Controller public class HomeController : Controller { public ActionResult Index() { return View(); } } // WebAPI Controller public class ApiController : ApiController { public IHttpActionResult Get() { // API logic return Ok("API data"); } }

  2. "Use MVC and WebAPI routing simultaneously"

    • Description: Understand how to configure routing in an ASP.NET MVC project to handle both MVC and WebAPI routes concurrently.

    Code:

    // MVC Route routes.MapRoute( name: "MVCRoute", url: "{controller}/{action}/{id}", defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional } ); // WebAPI Route config.Routes.MapHttpRoute( name: "WebAPIRoute", routeTemplate: "api/{controller}/{id}", defaults: new { id = RouteParameter.Optional } );

  3. "Configure MVC and WebAPI controllers in Global.asax"

    • Description: Explore how to configure both MVC and WebAPI controllers in the Global.asax file to ensure proper initialization and routing.

    Code:

    // Global.asax protected void Application_Start() { AreaRegistration.RegisterAllAreas(); GlobalConfiguration.Configure(WebApiConfig.Register); // WebAPI configuration RouteConfig.RegisterRoutes(RouteTable.Routes); // MVC configuration }

  4. "Handle MVC and WebAPI requests in the same controller"

    • Description: Learn how to create a controller that handles both MVC and WebAPI requests, enabling code reuse for shared functionalities.

    Code:

    public class SharedController : Controller { public ActionResult Index() { // MVC logic return View(); } public IHttpActionResult GetData() { // WebAPI logic return Ok("API data"); } }

  5. "Shared authentication for MVC and WebAPI in one project"

    • Description: Understand how to implement shared authentication for both MVC and WebAPI controllers within the same project.

    Code:

    // Startup.cs public void Configuration(IAppBuilder app) { ConfigureAuth(app); ConfigureWebApi(app); } private void ConfigureWebApi(IAppBuilder app) { var config = new HttpConfiguration(); // WebAPI configuration app.UseWebApi(config); }

  6. "MVC and WebAPI controller attribute routing"

    • Description: Explore how to use attribute routing for both MVC and WebAPI controllers in the same project for a more declarative routing approach.

    Code:

    // MVC Controller with attribute routing [RoutePrefix("MVC")] public class HomeController : Controller { [Route("Index")] public ActionResult Index() { return View(); } } // WebAPI Controller with attribute routing [RoutePrefix("api")] public class ApiController : ApiController { [Route("GetData")] public IHttpActionResult GetData() { // API logic return Ok("API data"); } }

  7. "Use MVC views and WebAPI responses in the same controller"

    • Description: Learn how to create a controller that serves both MVC views and returns WebAPI responses based on the request type.

    Code:

    public class SharedController : Controller { public ActionResult Index() { if (Request.IsAjaxRequest()) { // WebAPI response return Json(new { data = "API data" }, JsonRequestBehavior.AllowGet); } else { // MVC view return View(); } } }

  8. "Enable CORS for MVC and WebAPI in one project"

    • Description: Understand how to enable Cross-Origin Resource Sharing (CORS) for both MVC and WebAPI controllers within the same project.

    Code:

    // WebApiConfig.cs public static class WebApiConfig { public static void Register(HttpConfiguration config) { // Enable CORS var cors = new EnableCorsAttribute("*", "*", "*"); config.EnableCors(cors); // Other WebAPI configuration } }

  9. "MVC and WebAPI versioning in a single project"

    • Description: Explore how to version both MVC and WebAPI controllers in a single project for managing changes and backward compatibility.

    Code:

    // WebApiConfig.cs public static class WebApiConfig { public static void Register(HttpConfiguration config) { // WebAPI versioning config.AddApiVersioning(); // Other WebAPI configuration } }

  10. "MVC and WebAPI dependency injection in one project"

    • Description: Learn how to configure dependency injection for both MVC and WebAPI controllers within the same project for better code organization and testability.

    Code:

    // Startup.cs public void Configuration(IAppBuilder app) { ConfigureDependencyInjection(); } private void ConfigureDependencyInjection() { var container = new UnityContainer(); // Register dependencies for MVC and WebAPI controllers container.RegisterType<IRepository, Repository>(); // ... // Set the Unity dependency resolver for MVC DependencyResolver.SetResolver(new UnityDependencyResolver(container)); // Set the Unity dependency resolver for WebAPI GlobalConfiguration.Configuration.DependencyResolver = new Unity.WebApi.UnityDependencyResolver(container); }
