"Inside SharpDevelop" is now free

The book "Dissecting a C# Application: Inside SharpDevelop" can now be downloaded for free on the Apress Website (Spotted at Eric Gunnerson's blog).

SharpDevelop is an open source .NET IDE. This book by the makers of SharpDevelop covers the process of creating this application. They talk about both general approaches and implementation details, explaining design patterns used and guidelines for refactoring, the same as stepping through the Add-In architecture or the Editor Control. I just finished reading the first two chapters and enjoyed it quite a lot. Even if you don't do C# or any other .NET language, you should give it a try.
