Why can't we use Multiple inheritance and garbage collector paralelly in .net

In Object-Oriented Programming you might heard about the problem called Diomand Problem.Diomand problem is ambigutiy that arise when Class B and Class C inherits from Class A and now if Class D inherits from both Class B and C .

Now if Class D instant called method which is defined in A ( Not overriden in Class D) and same method Overriden in Class B and Class C Differently than compiler does not recognized from which class does it inherits.

To over come this issue OOPS language like Java, C# restrict multipule inheritance in C#, Java. If you have to implement multiple inheritance in Java and C# than you have to implement interface and define all methods and member of that interface
