The Ultimate Scratchpad for C#, F# and VB

LINQPad is not just for LINQ queries, but any C#/F#/VB expression, statement block or program. Put an end to those hundreds of Visual Studio Console projects cluttering your source folder and join the revolution of LINQPad scripters and incremental developers.

Reference your own assemblies and NuGet packages. Prototype your ideas in LINQPad and then paste working code into Visual Studio. Or call your scripts directly from the command-line.

Experience LINQPad's rich output formatting, optional debugger and autocompletion, and the magic of dynamic development and instant feedback!

Tired of Querying in Antiquated SQL?

Well, you don't have to! With LINQPad, you can interactively query databases in a modern query language: LINQ. LINQPad includes an optimized engine to build typed data contexts on the fly, and includes drivers and formatters for:
LINQPad also supports all the LINQ APIs in the .NET Framework, including LINQ to XML, PLINQ, Entity Framework and LINQ to SQL.
"Fantastic Learning Tool!"
Scott Hanselman, Principal Program Manager, Microsoft
And when you need to, you can still query in good old-fashioned SQL — even if your back-end is SQLite, Oracle, MySQL or PostgreSQL — without any heavy installations!

LINQPad is also a great way to learn LINQ: it comes loaded with 500 examples from the book, C# 7.0 in a Nutshell. There's no better way to experience the coolness of LINQ and functional programming.

"This is one of those useful tools you just should always have around and 'linqed' to a hotkey"
Rick Strahl, West Wind Technologies

Experience the Legendary Dump!

LINQPad's Dump method is famous for its capacity to eat almost anything!

Tuned with numerous heuristics, it intelligently walks object graphs for the best possible output. It even turns lazy objects into hyperlinks and asynchronous values into placeholders whose content materializes in the future!

Images and bitmaps render as images and bitmaps, and types from Reactive Extensions and Dataflow fully animate.

Dump any WPF or Windows Forms object and it will actually render.

And when you need a traditional data grid or debugger watch window, it's there, too.
