ProtocolException: The remote server returned an unexpected response: (405) Method Not Allowed.(Resolved)


Last week I face this error while accessing the WebGet method of a restful service. Thanks to Pedrams post for providing the solution.

So here it is.


The error shows up because without creating a new context, proxy ends up using the POST verb which will eventually cause the above exception

To resolve it we need to create a new OperationContextScope everytime we make a call to a WebGet method.

Sample code:


        public interface ITwitterStatus



            [WebGet(UriTemplate = “/statuses/friends.xml”)]

            Message GetFriends();


    public partial class _Client


        protected string GetFriends()


            WebHttpBinding binding = new WebHttpBinding(WebHttpSecurityMode.TransportCredentialOnly);

            binding.MaxReceivedMessageSize = 99999999;

            binding.Security.Transport.ClientCredentialType = HttpClientCredentialType.Basic;

            binding.Security.Transport.Realm = “Twitter API”;

            using (WebChannelFactory<ITwitterStatus> cf = new WebChannelFactory<ITwitterStatus>(binding, new Uri(“;)))


                cf.Credentials.UserName.UserName = “username”;

                cf.Credentials.UserName.Password = “password”;

                ITwitterStatus proxy = cf.CreateChannel();


                using (new OperationContextScope((IContextChannel)proxy))


                    Message m = proxy.GetFriends();
