Question

I’d like to know if it’s possible to call a method on a WCF windows service while another one is executing ? I need this so I can call my Terminate method that sets a static variable shared by my threads that tells them to stop. But when I call the method on the service, it waits till the first one (Execute) is over before he takes the call…

You need to set the concurrency mode of the service behavior to ConcurrencyMode.Multiple like this:

[ServiceBehavior(ConcurrencyMode = ConcurrencyMode.Multiple)]
class MyService : IMyContract
{
    // ...
}

In this situation the framework will not try to synchronize access to the service instance allowing to execute multiple operations at the same time.
