A rather large and suspicious looking box arrived at my house yesterday. To my surprise, it was the first few copies of Fast ASP.NET websites. These have just rolled fresh off the press courtesy of Manning!
If you aren't familiar with the contents of the book, it is a step-by-step guide that shows you how to improve the performance of your ASP.NET websites. Each chapter comes with an easy to follow coding sample that you can build upon as you progress through the book. The code samples are written in both ASP.NET MVC and ASP.NET Webforms, so you can follow along regardless of your coding preference.
