INF Looking for means to dialog C#-Dev team about multiple inheritance.

Please help.

I really need multiple inheritance with C#. Is there any forum/means to have a dialog with the dev's for C# about this? The amount of extra work and maintenance costs of not having multiple inheritance has been a big problem, but lately, it has really become a burden for not having. The maintainability and reuse-ability of code is drastically reduced without it.
