Just for completeness, I believe C# fits with C++, which is something that can occasionally catch a Java developer.

  C# is actually a mix. It uses static dispatch by default, virtual dispatch like C++ and Object Pascal, dynamic dispatch like Objective-C.

    Interestingly, while the C# language uses static dispatch by default, it is at least the case that Microsoft's compiler always emits the `callvirt` instruction[1]. This is because the language spec requires that a method call to a null instance of a reference type must throw a NullReferenceException, and callvirt is apparently the cheapest way to do that on the CLR.

    I've only used C# very topically. Do you have any documentation that describes how it behaves?

      Not sure, I guess this video could be interesting: https://www.microsoft.com/resources/msdn/en-us/msdntv/20051103CLRJP.html https://www.microsoft.com/resources/msdn/en-us/msdntv/200511...
