How to call PUT method using httpwebrequest?

Tried Code:

var request = WebRequest.Create("http://localhost/RestfulTutorialService/Service.svc/Post"); request.Method = "PUT"; request.ContentType = "application/json"; using (var writer = new StreamWriter(request.GetRequestStream())) { var serializer = new JavaScriptSerializer(); var payload = serializer.Serialize(objBlogPost); writer.Write(payload); } var response = (HttpWebResponse)request.GetResponse(); var responseCode = response.StatusCode; 

Error:The remote server returned an error: (405) Method Not Allowed.

My service is a Restful service. Below is the method being called.

 [OperationContract] [WebInvoke(Method = "PUT", UriTemplate = "/Post", RequestFormat = WebMessageFormat.Json)] void UpdateBlogPost(BlogPost post);
