Respected Imar sir,
I am reading your book, beginning ASP.NET 3.5 and I came across chap 13. LINQ.

of cource you have told everything nicely...but when I came across internet i found following things which not included in above mensioned chapter.

1.Using Lambda Expressions
2.Extension Methods
3.code using IEnumerable<T>



I read many links and posts on this. But confusion increased as I open more links to read about this...as I didn't have base of this.

Can you please tell me about these all 3 concepts? why not they are included in book?

Thanks in advance
Sushant

They are not in the book because otherwise the book would have been 2000 pages... ;-)

They are advanced concepts, and are discussed in the Professional ASP.NET 4 book.

And Google is your friend:
