Hey guys,

I am running Mono 2.8.2 on Ubuntu Server 10.10. I have a self-hosted WCF
service that communicates with clients over netTcpBinding (no security, very
vanilla). The service comes up and establishes a listener just fine. When a
client connects this is the error I get:

Exception during finishing channel acceptance.
System.NotImplementedException: UpgradeRequetRecord
(Int32 initialByte) [0x00000] in <filename unknown>:0
() [0x00000] in <filename unknown>:0
  at System.ServiceModel.Channels.TcpDuplexSessionChannel.OnOpen (TimeSpan
timeout) [0x00000] in <filename unknown>:0
  at System.ServiceModel.Channels.CommunicationObject.Open (TimeSpan
timeout) [0x00000] in <filename unknown>:0

  at System.ServiceModel.Dispatcher.ListenerLoopManager.ChannelAccepted
(IChannel ch) [0x00000] in <filename unknown>:0
(IAsyncResult result) [0x00000] in <filename unknown>:0

How can I fix this? I am not doing anything fancy in my implementation. This
is just a simple netTcpBinding listening for connections with some basic
methods (all primitive types). This works fine on Windows and MoMA doesn't
see any issues with it (but I know it doesn't drill down that far).

Any help is appreciated!
