C# 3.0 in a Nutshell from Albahari brothers
We were earlier discussing about a cute little tool called QueryExpress. Now the writer of the tool (Joseph Albahari) has also authored a book along with his brother (Ben Albahari) on C# 3.0 in a Nutshell. A brief review of the book is also available on Albahari's homepage over here.
A quick run through of the companion website of the book really illustrates the vast deep exploration of it on C# 3.0 even upto and beyond Linq.
