Hello all, I want to learn LINQ but I dont have any idea from where to start can anyone help me out. Suggest book or any site from where I can start. thanks in advance.

LINQ is nothing but language integrated query and it can also be represented in lambda expressions as its also possible to be used via English phrases. If you want to learn LINQ, you can refer to the book LINQ in Action. Its a nice book and provides very deep knowledge and I think you must be aware about the power LINQ has got, you can do a lot for the collections be the source any... I also found LINQ very powerful.

Hi, the best resource I`ve ever seen over net is Microsoft 101 LINQ Samples. You can start from Restriction Operators.

Scott and Adam has provided nice options. I am also a beginner to LINQ I think that would be very helpful. Thanks to you both

Use LINQPad to write all your queries. Helps greatly.

I learned Linq from Linq in Action too. I prefer the dot syntax to the other type. google for linqpad too, its a great learning tool

As my experience LINQ in Action is good book for understanding the principles of LINQ, and LINQ-to-SQL in particular. C# in depth is good for understand how LINQ works at the language level and including query syntax, extension methods and expression trees. No matter if you are beginner.

LINQ is something like a coded sql script, in another word, write sql script via c#/VB. Microsoft has lots of materials on this topic, you can go http://msdn.microsoft.com/en-us/vcsharp/aa336746.aspx to get them

I would recommend Essential LINQ by Charlie Calvert and Dinesh Kulkarni. It covers all the essentials as well as background information on important topics such as lambdas and extension methods are essential to a full understanding of how LINQ works. There is a short section on PLINQ, but this was an example of technology when the book was written.
