Broken tests after installing TypeMock 5.2

Hello, the following code used to work:

var fakeCommand = Isolate.Fake.Instance<SqlCommand>(Members.ReturnRecursiveFakes);
Isolate.Swap.NextInstance<SqlCommand>().With(fakeCommand);
Isolate.WhenCalled(() => fakeCommand.ExecuteReader(0)).WillThrow(Isolate.Fake.Instance<SqlException>(Members.ReturnRecursiveFakes));

However, after upgrading to TypeMock 5.2 it throws the following exception:

TypeMock.TypeMockException :
*** Cannot use WhenCalled without a complementing behavior statement

I tried to split the last statement into two:

var fakeCommand = Isolate.Fake.Instance<SqlCommand>(Members.ReturnRecursiveFakes);
Isolate.Swap.NextInstance<SqlCommand>().With(fakeCommand);
var ex = Isolate.Fake.Instance<SqlException>(Members.ReturnRecursiveFakes);
Isolate.WhenCalled(() => fakeCommand.ExecuteReader(0)).WillThrow(ex);

Now I get:
TypeMock.TypeMockException :
*** Cannot mock methods defined in types from mscorlib assembly.

What I can see now that I can't mock SqlException:
Isolate.Fake.Instance<SqlException>();

And result is the same "cannot mock mscorlib" exception from TypeMock.

What should I do to handle this? It used to work prior 5.2 release.

Thanks in advance.
