2Can you explain what feature of multiple inheritance you are looking for in C#, and maybe we can recommend something else that will achieve your goals? – Dan Feb 18 '10 at 04:13

5Ten questions, zero accepted? When you get a best answer to a question, it would be courteous to select that as your accepted answer. It's a nice way of saying "thank you" to the people who take time to read and reply to your question. – Bob Kaufman Feb 18 '10 at 04:33

First, a small correction: C# does support multiple interface inheritance. It doesn't support multiple implementation inheritance.
The two big reasons MI isn't supported are:
Chances are good that you can do what you want with multiple interface inheritance anyway.
It adds a lot of complexity to the compiler implementation.
IMO, in many cases, the availability of multiple inheritance in a language causes that feature to be frequently abused. Single inheritance already gets wedged into a lot of class hierarchies unnecessarily when something like composition would do just as well.
