Mock class but exempt some members

Hi,

Yes you can do that, in the example that you gave you can fake only the instance methods of MyClass and the static field of s_DummyClass will not be faked.

[TestMethod]
public void Test()
{
    // Isolate.Fake.Instance without parameters is like using Members.ReturnRecursiveFakes
    var fake = Isolate.Fake.Instance<MyClass>();
}

Another option is to fake MyClass but use the Members.CallOriginal default
and fake explicitly the methods you are interested in.

[TestMethod]
public void Test()
{
    var fake = Isolate.Fake.Instance<MyClass>(Members.CallOriginal);
    Isolate.WhenCalled(() => fake.GetI()).WillReturn(5);
}

Please let me know if it helps.
