I have a WCF service which is hosted in a Windows Service and has net.tcp endpoint. The clients are in the same LAN (Workgroup) as the service but they don’t have the server’s Windows user accounts.
PS: When I set the Security.Mode to None in both client and server, I receive the following error:
The requested upgrade is not supported
by ‘{SERVICE ADDRESS}’This could be due to mismatched
bindings (for example security enabled
on the client and not on the server).
OK, I solved the problem.
I don’t know why it is like this, but if I uncheck the “Use simple file sharing” in Folder Options of the server, everything works perfectly.
