Question

Contract requires Session, but Binding 'BasicHttpBinding' doesn't support it or isn't configured properly to support it.

my web.config

Answer 1

A couple of things you might want to look at is that you have serviceMetadata turned off. No client will ever be able to discover your endpoint if you don't publish it. Once you enable it you need to provide a http address to publish the data.
