Faking static and instance methods

Sure.

For example:

class MyClass
{
   static public int StaticMethod() { return 1; }
   public int InstanceMethod() { return 1;}
}

[Test]
public void Test()
{
      Isolate.Fake.StaticMethods<MyClass>();
      Isolate.WhenCalled(() => MyClass.StaticMethod).WillReturn(2);
      var fakedInstance = Isolate.Fake.Instance<MyClass>();
      Isolate.WhenCalled(() => fakedInstance.InstanceMethod).WillReturn(3);

      Assert.That(MyClass.StaticMethod(), Is.EqualTo(2));
      Assert.That(fakedInstance.InstanceMethod(), Is.EqualTo(3));
}

Yes thanks - that of course works fine. In the classes I was trying to test there were a lot of threads being started up in the background, and there was a WCF layer mixed up in it, which made it hard for me to see the wood for the trees.
