LINQPad 4.3

LINQPad is also a great way to learn LINQ: it comes loaded with 500 examples from the book, C# 4.0 in a Nutshell. There's no better way to experience the coolness of LINQ and functional programming.
And LINQPad is more than a LINQ tool: it's an ergonomic C#/VB/F# scratchpad that instantly executes any expression, statement block or program with rich output formatting – the ultimate in dynamic development. Put an end to those hundreds of Visual Studio Console projects cluttering your source folder!
Best of all, LINQPad standard edition is free and can run without installation (or with a low-impact setup). The executable is 3MB and is self-updating. There is even a version that runs in Google Chrome.
