The author is apparently quite knowledgeable in MSBuild & ClickOnce, and shared some of the insights in this book, such as how to customize your build. The main negative is that, he sometimes just jumps into a topic or use a term without properly explaining the the fundamentals. For example, incremental build is a big topic that's not properly explained.
It's would have been much better to give a clear "problem statement" about the fundamental problem that incremental build is supposed to solve, then describe how this can be done logically, then show how the specific technology (ie msbuild) does this; but he tends to belabor the technologies used instead.
Another problem is that the author didnt do his homework well and incorrectly described several terms: e.g he said SCM stands for "Source Control Management", which we all know should be Software Configuration Management. He said BITS is Binary Intelligent Transfer Service (when it should be Background ...). This sort of things tend to undermine his credibility.
