I have a Windows application that must "log in" to a remote service.
Once logged in, for all subsequent service calls the Windows
application should somehow pass a "session context" in each message to
the service, which will then be compared to session information stored
in SQL Server. However, for each service call a new client proxy is
created, i.e. I'm not reusing the same proxy over and over.
Essentially, I need to emulate what traditional ASP.NET sessions do.

I've done pretty much all the research I can looking into WCF
federation (RSTRSTR) but haven't come up with anything understandable.
I also know that WCF's concept of a session is not inherently
sufficient for what I'd like to do. I was curious what best practices
there were or whether anyone else has attempted something like this.

Thanks.
