WHAT WERE YOU THINKING!!!!

I just looked a little deeper in the changes you made from MDX1 to MDX2...You have change WAY too many calls, parameters and other "little" things....

Of course you will say "its much better readable now" BUT WHO CARES!!!!! You just messed up cross-platform Development with all you .NET Compact Framework ISVs!

MD3DM (Managed D3D Mobile) is shipping with VS2005 and you bomb them one month before Release with a totally incompatible verison of MDX!

Are you not talking to these guys?
Are you not looking outside your office that there is another world out there?

No wonder nobody has shipped MDX games yet...first the mess with the sample frameworks (changing them in every release with no backwards compatilibity) and than "fixing" the APIs to be more "Whidbey Conform".

Well, so much for some christmas games...back to the drawing board and figure out how to manage the two codepath...and looking forward to DX10 I see another path coming...and no help from your side.

I still love MDX but its time you learn that you cannot mess with the interfaces if you want ISVs to ship apps/games at some point in time

I agree fully with Chris Muench. You're making our company have horrible transitions from our previous code to the newest versions. Our next meeting is discussing the use of OpenGL for our next project. The truth is simple: we like Microsoft, but we can't keep up with them.
