Question

I can establish remote communication betweeen client and server but every time the client calls a method on the Client Activated remotable object I get a System.Net.WebException:

{"The underlying connection was closed: An unexpected error occurred on a receive."}

There is a System.IO.IOException INnerException
{"Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host."}

The stack trace is this:

"\r\nServer stack trace: \r\n

For all it’s worth, the problem was solved when I changed the channel on the server and client from http to tcp.
