I have the following class that configures security, encoding, and token parameters but I am having trouble adding a BasicHttpBinding to specify a MaxReceivedMessageSize. Any insight would be appreciated. public class MultiAuthenticationFactorBinding { public static Binding CreateMultiFactorAuthenticationBinding() { HttpsTransportBindingElement httpTransport = new HttpsTransportBindingElement(); CustomBinding binding = new CustomBinding(); binding.Name = "myCustomBinding"; TransportSecurityBindingElement messageSecurity = TransportSecurityBindingElement.CreateUserNameOverTransportBindingElement(); messageSecurity.AllowInsecureTransport = true; messageSecurity.EnableUnsecuredResponse = true; messageSecurity.MessageSecurityVersion = MessageSecurityVersion.WSSecurity11WSTrust13WSSecureConversation13WSSecurityPolicy12; messageSecurity.SecurityHeaderLayout = SecurityHeaderLayout.Strict; messageSecurity.IncludeTimestamp = true; messageSecurity.SetKeyDerivation(false); TextMessageEncodingBindingElement Quota = new TextMessageEncodingBindingElement(MessageVersion.Soap11, System.Text.Encoding.UTF8); Quota.ReaderQuotas.MaxDepth = 32; Quota.ReaderQuotas.MaxStringContentLength = Int32.MaxValue; Quota.ReaderQuotas.MaxArrayLength = 16384; Quota.ReaderQuotas.MaxBytesPerRead = 4096; Quota.ReaderQuotas.MaxNameTableCharCount = 16384; X509SecurityTokenParameters clientX509SupportingTokenParameters = new X509SecurityTokenParameters(); clientX509SupportingTokenParameters.InclusionMode = SecurityTokenInclusionMode.AlwaysToRecipient; clientX509SupportingTokenParameters.RequireDerivedKeys = false; messageSecurity.EndpointSupportingTokenParameters.Endorsing.Add(clientX509SupportingTokenParameters); //binding.ReceiveTimeout = new TimeSpan(0,0,300); binding.Elements.Add(Quota); binding.Elements.Add(messageSecurity); binding.Elements.Add(httpTransport); return binding; } }
