Named pipes: C# server, C++ client

Question

I wrote 2 pairs of named pipe client/server programs: 1st pair in C# (.NET 4) 2nd pair in C++ (un-managed)

All 4 test programs use the same pipe name \\.\pipe\mypipe

The C# pair work fine with each other - I send a message from the client and it is received by the server. The C++ pair work also fine with each other.

But... when I try to run the C# client with the C++ server, or the C++ client with the C# server - then it doesn't work. The client is unable to connect to the server.

Is there something preventing the C++ client from working with the .NET server? Should it work?

Thank you.

NamedPipeClientStream and NamedPipeServerStream prefix "\\.\pipe\" to the name automatically.

C++ client code:

hPipe = CreateFile("\\\\.\\pipe\\mypipe", ...)

corresponding C# server code:

var pipe = new NamedPipeServerStream("mypipe", ...)
