LINQPad

LINQPad is a powerful and lightweight code scratchpad for .NET developers, designed for writing and testing C#, F#, VB.NET, and SQL code interactively. Whether you're querying databases, exploring .NET APIs, or prototyping business logic, LINQPad provides a fast and flexible environment without the overhead of a full IDE. Originally built to experiment with LINQ queries, LINQPad has evolved into a versatile tool used daily by developers for everything from ad hoc data analysis to rapid prototyping. It supports a wide range of data sources, integrates smoothly with Entity Framework and EF Core, and includes features like autocompletion, output formatting, and NuGet integration. LINQPad is ideal for anyone working with .NET who wants to write, test, and iterate quickly—without the ceremony of creating full projects. Key features include: • Run C#, F#, VB.NET, and SQL code snippets instantly • Autocompletion and IntelliSense, even for custom assemblies and NuGet packages • Query SQL Server, SQLite, PostgreSQL, Oracle, MySQL, and more • Built-in support for LINQ to Objects, LINQ to SQL, Entity Framework, and EF Core • Interactive output with rich formatting, charts, and tables • Full debugger, IL disassembler, and performance profiling (in premium editions) • Extensible with custom data contexts and external assemblies LINQPad is widely used by .NET professionals for learning, debugging, and rapid development.
