Error in faking the manage object

0 votes

I have a test that uses a c++ managed wrapper (which has unmanaged members)

Now, I would like to Isolate the c++ managed wrapper and run my test.

 

I mytest, I have the following lines, I want to mock the GetReaderInfo of ManagedWrapper

            var fakeReader = Isolate.Fake.Instance<Reader>(Members.ReturnRecursiveFakes);
            Isolate.Swap.AllInstances<Reader>().With(fakeReader);
            Isolate.WhenCalled(() => fakeReader.GetReaderInfo()).WillReturn(myreaderinfo);
 
I get the following error
