The requested resource does not support HTTP method 'GET'

Question

My route is correctly configured, and my methods have the decorated tag. I still get \"The requested resource does not support HTTP method \'GET\'\" message?

Answer 1

Please use the attributes from the System.Web.Http namespace on your WebAPI actions:

    [System.Web.Http.AcceptVerbs("GET", "POST")]
    [System.Web.Http.HttpGet]
    public string Auth(string username, string password)
    {...}

The reason why it doesn't work is because you were using the attributes that are from the MVC namespace System.Web.Mvc. The classes in the System.Web.Http namespace are for WebAPI.
