IIS 10.0 Detailed Error - 404.0 for [httpDelete] [

问题:

I'm trying to make an api in ASP.NET MVC. Unfortunately I have problem with two HTTP requests: DELETE and PUT

    [ActionName("Index")]
    [HttpGet]
    public String Index()
    {
        return "get";
    }

    [ActionName("Index")]
    [HttpPost]
    public String IndexPost()
    {
        return "create";
    }


    [ActionName("Index")]
    [HttpPut]
    public String IndexPut()
    {
        return "update";
    }
    [ActionName("Index")]
    [HttpDelete]
    public String IndexDelete()
    {
        return "delete";
    }

GET and POST requests are working perfectly fine when I'm trying to sent DELETE OR PUT then browser returns IIS 10.0 Detailed Error - 404.0 - Not Found.
