Tired of querying in antiquated SQL?

Well, you don't have to!  LINQPad lets you interactively query databases in a modern query language: LINQ.  Kiss goodbye to SQL Management Studio!

LINQPad supports everything in C# 4.0 and Framework 4.0:

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

And that's not all - you can also query:

• OData / WCF Data Services - including StackOverflow
• SQL Azure, SQLite and MySQL Enterprise Server
• Mindscape LightSpeed ORM
• (Even old-fashioned SQL!)

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 just a LINQ tool: it's an ergonomic C#/VB scratchpad that instantly executes any C#/VB 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.

Prerequisites

LINQPad requires .NET Framework 3.5 (or Framework 4.0 for LINQPad 4.x).

If you have Visual Studio 2008 or Visual C# 2008 Express, then Framework 3.5 will already be installed. 

LINQPad supports SQL Express, SQL 2000, SQL 2005, and (with some limitations) SQL 2008.

LINQPad standard edition is free to download and use. Autocompletion is an optional extra.
