I am a beginner to game development and as I am used to programming in C# I decided to go for XNA. I've been playing around with it for a while and now I am learning the basics of HLSL shaders, I have noticed in the MSDN documentation that there have been some syntax changes in HLSL between DirectX 9 and DirectX 10, for example, the Sampler type

Since I am having some troubles with my desktop pc, I am using my laptop which video card only supports DirectX 9.0c. Then I'm gonna have to write my shaders using the DirectX 9 syntax, right? So I am wondering, will my HLSL shaders written using the DirectX 9 syntax work on a system running DirectX 10 (or higher)?

Using XNA ContentPipeline to export a file in a machine without full XNA GS

My game uses the Content Pipeline to load the spriteSheet at runtime. The artist for the game sends me the modified spritesheet and I do a build in my machine and send him an updated project. So I'm looking for a way to generate the xnb files in his machine (this is the output of the content pipeline)… >>> More

The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
