WCF contract mismatch problem
- by Tom
Hi there,
I have a client console app talking to a WCF service and I get the following error:
"The server did not provide a meaningful reply; this might be caused by a contract mismatch, a premature session shutdown or an internal server error."
I think it's becuase of a contract mismatch but i can't figure out why. The service runs just fine by itself and the 2 parts were working together until i added the impersonation code.
Can anyone see what is wrong?
Here is the client, all done in code:
NetTcpBinding binding = new NetTcpBinding();
binding.Security.Mode = SecurityMode.Message;
binding.Security.Message.ClientCredentialType = MessageCredentialType.Windows;
EndpointAddress endPoint = new EndpointAddress(new Uri("net.tcp://serverName:9990/TestService1"));
ChannelFactory<IService1> channel = new ChannelFactory<IService1>(binding, endPoint);
channel.Credentials.Windows.AllowedImpersonationLevel = TokenImpersonationLevel.Impersonation;
IService1 service = channel.CreateChannel();
And here is the config file of the WCF service:
<configuration>
<system.serviceModel>
<bindings>
<netTcpBinding>
<binding name="MyBinding">
<security mode="Message">
<transport clientCredentialType="Windows"/>
<message clientCredentialType="Windows" />
</security>
</binding>
</netTcpBinding>
</bindings>
