Thanks for this book recommendation ... I'm in a similar situation, in that I have the need to quickly get up to speed on C# for a work project ... modifying existing C#, not writing it from scratch :) I do have some experience programming in various languages, and even have written some OOP stuff (in a language no one uses any more, ha ha). So I'll be able to skip some of the more basic concepts ... but I've had no formal cs courses, so having the big picture will be helpful if I want to understand better the context of the code I'm reading. :thumbsup: jrd
