I got the new book on MSBuild and Team Build, "Inside the Microsoft Build Engine: Using MSBuild and Team Foundation Build", last week and I've just gone through it. The book is written by Sayed Ibrahim Hashimi and William Bartholomew, two authorites on the subjects. I've used Hashmi's "Deploying .NET Applications: Learning MSBuild and ClickOnce" as a reference for MSBuild until now, but the new book will definately be the new resource for everyone wanting to know the ins-and-outs of MSBuild and Team Build.
The book covers MSBuild and Team Build first with the basics and then with deep-dives that cover topics that are hard to find in one place. There are also a couple of scenario-oriented chapters, "cookbooks", which adds real-world applications to the story.
A great book and I will use it a lot!
