Introduction to
Microsoft XNA
and how it can affect you and your children …
presented by Jon Davis
From Manual to Managed Code
Windows 95 era: Game developers begged for better (abstracted)
access to hardware resources
Microsoft came up with DirectX
People were concerned about performance, but DirectX proved itself
.. Fast forward ..
DirectX 8 introduces the programmable shader
Type libraries exposed to Visual Basic
.. Fast forward ..
Microsoft .NET replaces VB6
People need access to DirectX from .NET (not VB6)
Microsoft introduces Managed DirectX
People start grumbling that Managed DirectX being only a wrapper
for C++ doesn’t save them development time
From Windows to the Console
To this point, all platforms have been
supported by Microsoft
The desktop PC
The server
Tablet PCs
Pocket PCs
Smart phones
Embedded XP
.. except for Xbox 360
From Business to Gaming
Game development has always required a
very special set of niche skills
It has always been very difficult for
business professionals to develop
enthusiast game programming skills
C++ has traditionally been the de-facto
standard for games, but most software
developers use a higher level language
(Java, C#, VB.NET)
