New Post: Trying to create a stream - autofac throws error

The requested service 'Tweetinvi.Core.Interfaces.Streaminvi.IFilteredStream' has not been registered. To avoid this exception, either register a component to provide the service, check for service registration using IsRegistered(), or use the ResolveOptional() method to resolve an optional dependency.

                    Console.WriteLine("You received the message : {0}", a.Message.Text);
                };
