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# 5.0 and Framework 4.x:

• LINQ to Objects
• LINQ to SQL, Entity Framework
• LINQ to XML
• Parallel LINQ
• OData / WCF Data Services, SharePoint, and Windows DataMarket
• Microsoft's ubercool Reactive Extensions

And that's not all - there's also specific support for:

• SQL Azure, SQL Table Storage, Oracle, SQLite and MySQL
• Microsoft StreamInsight
• Microsoft Dynamics CRM
• Third-party ORMs including Mindscape LightSpeed, DevArt's LinqConnect, LLBLGen, DevExpress eXpress Persistent Objects and DevForce
• (Even old-fashioned SQL!)

LINQPad is also a great way to learn LINQ: it comes loaded with 500 examples from the book, C# 5.0 in a Nutshell.  There's no better way to experience the coolness of LINQ and functional programming.

LINQ is just the beginning

Querying is merely a special case of using LINQPad. More generally, LINQPad is a C#/VB/F# scratchpad that instantly executes any expression, statement block or program with rich output formatting and a wealth of features that "just work". Put an end to those hundreds of Visual Studio Console projects cluttering your source folder and join the revolution of LINQPad scripters, testers, and incremental developers. Reference your own assemblies and NuGet packages. Script in your favorite .NET language with optional autocompletion and the entire .NET Framework at your fingertips. Experience the magic of dynamic development and instant feedback in the ultimate programmer's playground!

Free and light

Best of all, LINQPad standard edition is free and doesn't slow down your computer when you install it! (There's even a standalone executable, and a version that runs in Google Chrome.) The program is under 5MB and is self-updating.

Prerequisites

LINQPad requires .NET Framework 4.0/4.5 (or Framework 3.5 for LINQPad 2.x).

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