Hi Brian
You are right about the documentation. We'll fix it up.
Basically it lets you define the default behavior for static methods.
The default is Members.ReturnRecursiveFakes
So you can change it by using the overload
FakeStaticMethods(Type, Members)
For example to set the default to call original methods use:
Isolate.Fake.StaticMethods(typeof(UserNotification), Members.CallOriginal);
Hope it clears things up. :)
