wcf bindings - ws, pipes, msmq...

http://msdn.microsoft.com/en-us/library/ms730879.aspx shows the standard/default list of bindings in WCF, including
- serialization in each binding
- session support in each binding

"Basic" uses web service. I think a lot of wcf apps use this.

Most bindings use binary serialization. Web service bindings use xml serialization.
