Why Multiple inheritance is not supported in .NET

Multiple Inheritance:

Multiple inheritance may allow you to write compact code but it has some program difficulties like "diamond problem" for example

Diamond problem :



class BaseClass
{
public abstract void Display();
}

class A : BaseClass
{
public override void Display()
{
Debug.WriteLine("First Child A");
}
}

class B : BaseClass
{
public override void Display()
{
Debug.WriteLine("Second Child B");
}
}

//Now Suppose that c# support multiple inheritance

class C : A, B
{
}

public class MainClass
{
public static void main()
{
C ObjC =new C();
ObjC.Display();
}
}

By excuting ObjC.Display() method Diamond problem is generated. It means which Display method going to executed.
