Linqpad Premium 9.8.12
 

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.
Want to test a variation of your script? Clone your query in a single keystroke! Experience LINQPad's rich output formatting, optional debugger and autocompletion, and the magic of dynamic development and instant feedback!
Query Databases in a Modern Query Language
With LINQPad, you can interactively query databases directly in LINQ (as well as SQL). The big win with LINQ is having association properties automatically generated for all relationships (inferred from foreign key constraints), so you can access related rows without joining! LINQPad uses a custom high-performance scaffolding engine behind the scenes, and includes drivers for SQL Server, SQL Azure, Oracle, SQLite, PostgreSQL and MySQL.
When dumped, association properties appear as lazy hyperlinks that can be expanded just by clicking on them. You can walk your entire database interactively!
