What is the threading model for WCF services?

[Tom P.]

I'm translating a service to use WCF and we need to make sure we are
thread-safe (or that we don't need to be). Is WCF apartment threaded
or does it create a new AppDomain for each call? If I get two calls at
the same time will they interfere with each other? Do I have to make
stuff singleton?

I just don't need people paying there bills twice at the same time.

This is totally configurable with attributes on the service itself.

Thanks, but that's apparently only half the equation.

A colleague found this article that gives a good run-down of the two
settings and how they work together.
