Except that then you heard wrong I'm afraid. A (very) short list:

Eiffel#: Multiple Inhertance and Assertions dropped, both major semantic
differences.

VB.NET: VB gone fully OO (big changes here). Indexing start changed from
1 to 0, maybe unimportant but a good indicator of what kind of problems
you can expect. Some seem to claim this is an entierly new language that
share syntax with VB, I don't know enough to have an informed opinion
here.

C++.NET: Multiple Inhertiance dropped.

Python.NET: (research implementation): MI dropped, the ability not to call
base class constructors causing grief.


And this list goes on. Ruby would probably have problems with continuations
not being supported, having implications on code blocks and closures.
