That isn't my decision to make. Managed DirectX uses value types for Matrix and several other types. Overall, I agree with the decision.
I'm certainly not going to waste my time rolling another managed interop layer for DirectX. -- arlie -----Original Message----- From: Unmoderated discussion of advanced .NET topics.

Because the DX api is a COM api, which works with objects and pointers, something you can mimic with classes in C# and references to objects. Structs in .NET should, correct me if I'm wrong, be used to create somewhat specialized value types, like a 'Coordinate', and then also just for .NET, not for COM interop. Because there are some drawbacks on structs, like manipulating them in a boxed situation (array list for example) is cumbersome, it's IMHO best to use classes instead of structs, especially when it comes to DX interop.
