Mocking ctor with AAA

I just started looking at the new AAA functionality in 5.0, so I may have missed some really basic stuff, but I can't seem to find the option for mocking the ctor of a type as well as any relevant method calls.

E.g. If I have the following

var fake = Isolate.Fake.Instance<MyType>();

the ctor of MyType seems to be called no matter what I do. I have tried to specify the different Member options when creating the Fake to no avail. Since WhenCalled takes an Action or a Func I assume it can't be used to cover the ctor.

Please advice.

Best regards,
