MVC-Web API: 405 method not allowed

Question

So, I am stuck in a strange behavior, that is, I am able to send(or POST) data using Postman (plugin of chrome) or using RESTClient(extension of Firefox)<

Answer 1

WebApi probably blocks the CORS request. To enable CORS on WebApi, use the Microsoft.AspNet.WebApi.Cors package. For further details, check http://www.asp.net/web-api/overview/security/enabling-cross-origin-requests-in-web-api

Answer 2

Removing "using System.Web.MVC" from controller class solved this problem for me.

Answer 3

No need webconfig, all you need is to add:

  services.AddCors(o => o.AddPolicy("MyPolicy", builder =>
            {
                builder.AllowAnyOrigin()
                       .AllowAnyMethod()
                       .AllowAnyHeader();
            }));

Answer 4

Ok. Solved the problem with the help of @martennis answer, but with a little correction.

Every things perfect, just to take care is, we need to enter following command in Package Manager Console:

Install-Package Microsoft.AspNet.WebApi.Cors –IncludePrerelease

Instead of the one shown in the link provided by, @martennis, and after that, my WebApiConfig.cs was updated as follows:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web.Http;
using System.Web.Http.Cors;

namespace WebApiRESTfulwithJSON
{
    public static class WebApiConfig
    {
        public static void Register(HttpConfiguration config)
        {
            // Web API configuration and services
            var cors = new EnableCorsAttribute("*", "*", "*");
            config.EnableCors(cors);

            // Web API routes
            config.MapHttpAttributeRoutes();

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

Hence, solved the problem...!!!

Now, I will able to use my web services from anywhere, calling it from mobile applications, web applications or desktop applications.

For, how to create them from scratch, I wrote my first blog on this (...inspite of being android developer, never tried to write a blog for Android :-P Anyways...)
