Error occurs while calling HttpPut and HttpDelete in C# WebAPI

Question

I have a WebAPI 2 controller. Very easy, very simple:

public class ValuesController : ApiController
{
    // GET api/values
    public IEnumerable<string> Get()
    {
        return new string[] { "value1", "value2" };
    }

    // GET api/values/5
    public string Get(int id)
    {
        return "value";
    }

    // POST api/values
    public void Post([FromBody]string value)
    {
    }

    // PUT api/values/5
    public void Put(int id, string value)
    {
    }

    // DELETE api/values/5
    public void Delete(int id)
    {
    }
}

Get and Post methods work well. But Delete and Put do not work. And this error occurs:

HTTP Error 404.0 - Not Found The resource you are looking for has been removed, had its name changed, or is temporarily unavailable.

*All methods work well in IIS Express. But not in IIS Local Any idea why is that happening? Thanks in advance

Answer 1

From where you are sending request to this methods? From AJAX request? GET (with id) PUT and DELETE have same route URL. You have to specify the verb if you are calling via AJAX. Otherwise application gets confused between GET, PUT and DELETE.
