Book. Done.
Along with the rest of the ASPAlliance I have contributed to the ASP.NET Cookbook, which I hear is finally finished all but the shouting :O)
I originally volunteered to do the whole of the GDI+ chapter but due to various reasons (me being crap being one of them <g>) it didn't quite work out that way :O(
This is the third book I have contributed to, probably going to be the first one that I can actually find in a book shop once published. The first one is from Syngress who are probably too small a presence in the UK to get a foothold in stores over here. Although the second one was published by Wrox (who are huge in technical books) the subject is niche (GDI+).
I'm going to keep writing until I can hold my daughter up in a book shop and say "your daddy did that" ;O)
