How do I only mock non static constructors?

Hello,

I want to mock a custom class, but only "normal" constructors. For doing so I use Reflective Mocks, as the class does not have any public constructors:

Mock SystemImageListMock = MockManager.Mock(typeof(SystemImageList), Constructor.StaticNotMocked);

However the static constructor is not called! This only happens when using

Mock SystemImageListMock = MockManager.Mock(typeof(SystemImageList), Constructor.NotMocked);

... but using this snippet, also the "normal" constructor is not mocked!

What is my mistake? What am I doing wrong?

Thanks for your help
