Aaron Reed has extensive software development experience and more importantly, experience in software development education. Since 2004 he has taught courses at Neumont University in .NET, web development and web services, XNA, systems design and architecture, and more. Aaron's experience in teaching both DirectX and XNA for several years to university-level students helps him understand what topics are easily understood and which ones need more depth and emphasis. Through experience in the classroom he also has a good understanding of what format and sequence makes the most sense to present the material. This book follows that format and is meant to present game development concepts in the way most efficient and most comprehendible as proven in the classroom.
