Since I have converted my WCF methods to Async, my unit tests have failed, and I can\'t figure out the correct syntax to get them to work.

I think you need to return the Task from the DoSomething mock
Task
DoSomething
this._mockService.Setup(x => x.DoSomething(It.IsAny(), It.IsAny())) .Returns(Task.FromResult(0));
