405 Method not allowed in calling to WebAPI

Question

I am calling using following request to a web service (copypaste from Chrome dev panel):

 Request URL:https://localhost:44300/api/userpreferences
 Request Method:POST
 Status Code:405 Method Not Allowed
 Request Headersview source
 Accept:application/json, text/plain, */*
 Accept-Encoding:gzip,deflate,sdch
 Accept-Language:ru-RU,ru;q=0.8,en-US;q=0.6,en;q=0.4
 Connection:keep-alive
 Content-Length:51
 Content-Type:application/json;charset=UTF-8
 Host:localhost:44300
 Origin:http://localhost:3000
 Referer:http://localhost:3000/
 User-Agent:Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/33.0.1750.154 Safari/537.36
 Request Payloadview source
 {userName:asasa, projectId:2}
 projectId: 2
 userName: "asasas"

to a webservice method that has such a signatue:

   [HttpPost]
    public replyObj setCurrentProject(string userName, int projectId)
    {
    /// ... 
    }

as you see I followed interface in every detail. If I change method to PUT, other method is called with [HttpPut] attribute even if sugnature does not match, and this config just gives me {"Message":"The requested resource does not support http method 'POST'."} contrary to what I declared.

this may help : blog.dontpaniclabs.com/post/2013/01/23/… ..........System.Web.Http" and "System.Web.Mvc" have an "[HttpPost]" attribute use the "[System.Web.Http.HttpPost]" attribute — Zaki

Recently I've faced with the same problem. It seems that your method signature doesn't match the route. Change your method to

public replyObj setCurrentProject(dynamic value)
{
/// ... 
}

or you can use your appropriate class instead dynamic
