I’d like some feedback from readers, and I suspect my blog is the simplest way to get it.
I’m currently writing chapter 15 of C# in Depth, tentatively about Code Contracts and Parallel Extensions. The problem is that I’m 15 pages in, and I haven’t finished Code Contracts yet. I suspect that with a typesetter moving the listings around a little it can be shortened a little bit, but I’m still concerned. With the amount I’ve still got to write, Code Contracts is going to end up at 20 pages and I expect Parallel Extensions may be 25. That makes for a pretty monstrous chapter for non-language features.
I’d like to present a few options:
- Keep going as I am, and take the hit of having a big chapter. I’m not going into huge amounts of detail anyway, but the bigger point is to demonstrate how code isn’t what it used to be. We’re no longer writing a simple series of statements to be executed in order. Code Contracts changes this dramatically with the binary rewriter, and Parallel Extensions adjusts the parallelism, and ironically makes it easier to write asynchronous code as if it were executed sequentially.
- Try to whittle the material down to my original target of around 35 pages. This means it’ll be a really cursory glance at each of the technologies – I’m unsure of how useful it would be at all at that point.
- Don’t even claim to give enough information to really get people going with the new technologies, but possibly introduce extra ones as well, such as PostSharp. Build the theme of "you’re not writing C# 1 any more" in a stronger sense – zoom back to show the bigger picture while ignoring the details.
- Separate them into different chapters. At this point half the new chapters would be non-language features, which isn’t great for the focus of the book… but at least they’d be a more reasonable size.
- Ditch the chapters from the book completely, possibly writing them as separate chapters to be available as a mini-ebook companion to the book. (We could possibly include them in the ebook version.) This would make the second edition more focused again and possibly give me a bit more space when revising earlier chapters. However, it does mean there’d only be two full-size new chapters for the second edition. (There’ll be a new "wrapping up" chapter as well for a sense of closure, but I’m not generally counting that.)
Other suggestions are welcome, of course. I’m not going to claim that we’ll end up doing whatever is suggested here, but I’m sure that popular opinion will influence the final decision.
