405不允许调用WebAPI的方法

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

 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.

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
