For the last year, aside from starting a great job with Bing, I’ve also been working on a book about C# 4.0 and the upcoming .Net framework. The news: it is finally available for presale! This book is not your typical C# reference. It’s designed to be an easy guide to how to accomplish specific tasks, using a problem/solution approach. Some examples:

• How to use P/LINQ (new in .Net 4!)
• Override Equals and implement IEquatable<T> correctly
• Enforce coding contracts (new in .Net 4!)
• Convert numbers to strings in arbitrary bases
• Various ways of rounding, including “snapping” to specific intervals.
• Dynamic discovery of WCF services
• Make your Silverlight 3 application run out-of-the-browser
• Speed up array access
• Easily split work among multiple processors
• Localize WinForms, WPF, ASP.Net, and Silverlight apps

…and hundreds of other topics, covering everything from the basics of C# to WPF, ASP.Net, interaction with the operating system, common application patterns and more. I cover all the new stuff that’s in both the C# language and the .Net 4 framework classes, as well as existing functionality.

Each topic begins with a brief description of when/where/why you would need to use the technique, followed by a brief explanation and source code.

I often just want a reference I can quickly dive into to remind me of how something is done. This book is my attempt to put in writing what I find valuable, both when I was learning C# and now when I just need to locate a sample quickly.

• C# 4.0 How-To at Amazon
• C# 4.0 How-To at Barnes and Noble

Over the next few months I’ll talk more about what’s in the book, and hopefully get back into blogging more programming topics.
