When I was looking for documentation or tutorials on how to create a RESTful WCF service that returns JSON-formatted data, I found lots of partial information and code examples, none of which completely worked. So when I finally figured out how to create it, I decided to write this article for those who may be in the same predicament as me.
This walk-through uses .NET 4.0, and Visual Studio 2010.
Recently I've been taking a closer look at LINQ, or Language-Integrated Query -- a set of C# and Visual Basic features that let you write SQL-like queries against data structures such as arrays or hashtables. I like how it lets you replace loops with just a line or two of code. I will illustrate it here with two simple exercises.
