CIL Programming: Under the Hood of .NET [Hardcover]

So what about Bock's Book: "CIL Programming: Under the Hood of .NET"? In a word - disappointing. Bock spends most of the book's first chapter entitled "Language Interoperability" on detailed discussion of programs written in a variety of languages. He's trying to make the point that the CLR allows programs written in different languages to freely interoperate. Duh? Why spend the better part of the book's opening talking about everything but CIL. There's even an Oberon (?) programming sample here.
The second and third chapters on ILASM Directives, and, CIL Opcodes, respectively, read like my weekend shopping lists. While it is true that programming books have to regurgitate all the nasty details of the programming language, the good books tell its readers how to internalize the information and describe useful ways of summarizing the information in one's mind. That is, the authors of the better books have figured out some rhyme and reason to the language and they share these insights with their readers. On the other hand, this is what I found in these two most important chapters of Bock's book: the more I read, the more questions I had. I wound up spending significant time on the NET trying to resolve questions that were raised in the material in these two chapters. Clearly, the author did not anticipate these questions.
The fourth chapter, "ILASM and CIL in Practice" is a decent discussion of a typical sample program in IL. It demonstrates some of the IL constructs and programming concerns discussed in the previous chapters.
Chapter 6 is interesting. Here the author talks about and contrasts the IL generated by various programming languages. Some of the VB.NET and C# exposés were eye-opening, but then Bock goes back to Oberon again.
The author ends off the book in chapters 7 and 8 with some very long and tedious samples. I got nothing from this. Chapter 9, the last in the book, is a two-pager on "CIL Tips".

So why do I give this book 3 stars?
1) The book includes Chapter 5, a well-written and interesting discussion about CIL Debugging.
2) Right now, Bock's book is one of three books that talk about CIL. It is the only book that is targeted directly at programming. Although John Gough's "Compiling for the .NET Common Language Runtime" is an excellent book, it is very specialized and targets would-be compiler authors. I didn't read the third book in the IL arena, Serge Lidin's "Inside Microsoft .NET IL Assembler", but I did thumb through it several times (you know what little that is worth): this book strikes me as being very difficult.

RECOMMENDATIONS:
If you need to learn IL Programming right now, buy Bock's book - read the second half of chapter 1, and read Chapters 2-5, maybe Chapter 6. If you have the time, money, and inclination, then buy and read Gough's book. You'll need a lot of time for Gough, but you will definitely learn.

If learning IL is not that pressing right now, I would wait to see if someone else releases a better book.
