Hi! I'm reading a book about DX11 programming with c++. In the book they just mentione something about XNA, and from what I understand it's built upon directx. Then my question is: is it a class library that you can use from within any language, like c++, c#? or is it a separate compiler like a 3d language similar to DBpro?

Can you create any DX devices? I mean, using any DX sdk. Is it stable? Is it easy to use? Easier than the DX API? Would you recommend it?

Best!

XNA is a DirectX wrapper for C#. C# is a pretty powerful language, though it's not as fast as C++ and only works on Windows platforms. The upside is that it's a lot easier to use XNA than it is to use pure DirectX in C++.

I suggest trying it out, and once you've got a decent grip on how DirectX actually works (remember not to get confused between directX and C#), you can then move onto C++.

XNA can be used for more than just the Windows. It can be used to make Xbox and windows phone 7 games.

Actually, C# as a language is available on a variety of platforms, including Mac OS X and Linux through the open source Mono project. That said, I know of no version of Xna that works on those platforms, as Direct X is not available on them.

Also, I've seen some benchmarks that place managed code written in C# code ahead of equivalent C++ code in certain situations - since everything is JIT compiled it gets pretty fast, and it really comes down to a variety of other, far more complicated and often situation specific factors.
