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?

Fantastic Learning Tool”

Scott Hanselman, Principal Program Manager, Microsoft

Full support for C# 12 and .NET 8 in LINQPad 8.

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 for SQL Server, SQL Azure, Oracle, SQLite, PostgreSQL and MySQL.

LINQPad can also connect to Entity Framework Core contexts that you create in Visual Studio. Expand lazy-loaded associations just by clicking hyperlinks, and see the SQL translation for every command sent to the database.

And when you need to, you can still query in good old-fashioned SQL. Use LINQPad to query SQL Server, SQLite, Oracle, MySQL or PostgreSQL — without installing any client software!

LINQPad is also a great way to learn C#: it comes with all 1300 examples from the book, C# 12 in a Nutshell, as well as interactive samples from Jon Skeet's C# in Depth.

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.
