Today's $10 Deal of the day from APress at http://www.apress.com/9781430225294 is "Pro ASP.NET 4 in C# 2010".
"ASP.NET 4 is the principal standard for creating dynamic web pages on the Windows platform. Pro ASP.NET 4 in C# 2010 raises the bar for high-quality, practical advice on learning and deploying Microsoft's dynamic web solution."
Alan Freeman is an excellent author - I recommend this book to all C# development teams.
