ASP.NET Web API - PUT & DELETE Verbs Not Allowed - IIS 8

Question

I recently upgraded from Visual Studio 2010 to the Visual Studio 2012 RC. The installer also installs IIS 8 Express which Visual Studio now uses as the default web server.

Answer 1

Enable CORS (nice and neat)

1.Add CORS nuget package

Install-Package microsoft.aspnet.webapi.cors

2.in the WebApiConfig.cs file to Register method add bellow code :

config.EnableCors();

ex:
using System.Web.Http;

namespace test
{
public static class WebApiConfig
{
    public static void Register(HttpConfiguration config)
    {
        // Web API configuration and services


        config.EnableCors(); //add this**************************


        // Web API routes
        config.MapHttpAttributeRoutes();

        config.Routes.MapHttpRoute(
            name: "DefaultApi",
            routeTemplate: "api/{controller}/{id}",
            defaults: new { id = RouteParameter.Optional }
        );           
    }
}
}

3.Add bellow code into namespace of the controller include get,post,delete,put or any http method

[EnableCors(origins: "The address from which the request comes", headers: "*", methods: "*")]

ex:

using System.Web.Http.Cors;//add this******************************
namespace Test.Controllers
{
[EnableCors(origins: "http://localhost:53681/HTML/Restaurant.html", headers: "*", methods: "*")]
public class RestaurantController : ApiController
{
    protected TestBusinessLayer DevTestBLL = new TestBusinessLayer();

    public List GET()
    {
        return DevTestBLL.GetRestaurant();
    }

    public List DELETE(int id)
    {
        return DevTestBLL.DeleteRestaurant(id);
    }       
}
}
