[Mono-osx] Mono - WCF

[Adam]

hi,

Your problem is, your WCF setup doesnt make sense for your purpose.
You are using:
InstanceContextMode=InstanceContextMode.PerCall

This means that a new instance of your service class is instantiated every
time a request comes in - so you will never be able to refer to an instance
of the service that started the thread (i.e., you will set ' needToExit =
true;' inside of a service that has just been created, and has no running
thread).

You need to change to another instance-context, such as Single, or
PerSession.
