ASP.NET MVC 4 - using post method

In Visual Studio 2010 I am using ASP.NET MVC 4 to create a web project api like in this example: https://www.youtube.com/watch?v=H9vBxAH4f5E

Everything works fine - I manage to use the method GET

, but when using the method POST

I have a problem:

No MediaTypeFormatter is available to read a 'String' object from content with media type "application / x-www-form-urlencoded".

Mine webapiconfig.cs

looks like this:

public static class WebApiConfig
{
    public static void Register(HttpConfiguration config)
    {
        config.Routes.MapHttpRoute(
            name: "DefaultApi",
            routeTemplate: "{controller}/{id}",
            defaults: new { id = RouteParameter.Optional }
        );

        FormUrlEncodedMediaTypeFormatter f;

        config.Formatters.Clear();
        config.Formatters.Add(new JsonMediaTypeFormatter());

        f = new FormUrlEncodedMediaTypeFormatter();
        f.SupportedMediaTypes.Add(new MediaTypeHeaderValue("text/html"));

        config.Formatters.Add(f);
        // application/x-www-form-urlencoded ???
    }
}

      

        
        
        
      

    

Why I am facing the problem:

No MediaTypeFormatter is available to read a 'String' object from content with media type "application / x-www-form-urlencoded".

Complete error message:

Message: "An error has occurred." ExceptionMessage: "No MediaTypeFormatter is available to read an object of type 'String' from content with media type 'application / x-www-form-urlencoded'."
