I am still searching for .NET framework book like that of Joe Duffy's Professional .NET framework. That book is excellent source of insights of .NET framework and techniques of languages that has not been covered by any book. I wish duffy write again for 3.5 or 4.0..If you know some book like this one pls pls let me know..
