Keyvan Nayyeri just announced the official release of his book about Visual Studio Extensibility, published by Wrox.
This is quite a unique book since the VSX technology is new with VS2005 and is a leap forward compared to the old macro-based extensibility, but nothing has been written on this topic, yet.
The book will cover all the aspects of Visual Studio Extensibility: Macro, Add-Ins, Visualizers, MSBuild, VSPackages, DSL tools, using the Shell.
I also what to thank Keyvan for adding me to his acknowledgement page on the book:
I would thank anyone else who helped us get this book done, both inside Wiley...
