Want to Learn How to Use LINQ? Check out LINQPad!
I was catching up with some of the people I follow on Twitter tonight (as a side note, I used to think Twitter was a waste of time but I'm actually finding it useful now days) and noticed that Scott Cate listed a link to a free tool called LINQPad. Wow...I wish I would've known about this tool a few months back when I was working on different LINQ queries for an application. It really simplifies building queries and also happens to be a great way to learn the LINQ syntax as well. It was created by Joseph Albahari for the C# 3.0 in a Nutshell book.

The LINQ Dilemma
Let me start off by saying that I'm a huge fan of Language Integrated Query (LINQ). If you've ever had to write code to loop through objects to locate properties and then filter the collection based upon specific values then you'll definitely have an appreciation for what LINQ has to offer. It's a phenomenal technology that will definitely make developing applications a more productive process. Scott Guthrie has some really nice tutorials that help jumpstart learning more about LINQ and LINQ to SQL that you can view here. For those that haven't seen many LINQ samples, here's a simple example of using LINQ to filter a collection of Customer types based upon a Country property:
