LINQPad supports everything in C# 4.0 and Framework 4.0:

  • LINQ to Objects
  • LINQ to SQL and Entity Framework
  • LINQ to XML
  • Parallel LINQ

And that’s not all – you can also query:

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.


LINQPad requires .NET Framework 4.0 (or Framework 3.5 for LINQPad 2.x).

If you have Visual Studio 2010 or Visual C# 2010 Express, Framework 4.0 will already be installed. 

LINQPad supports SQL Express, SQL 2008, SQL 2005, SQL 2000, SQLite, MySQL and Oracle.
