Quick summary
LINQPad 6 is a compact, interactive environment for .NET developers that makes it fast to try out code snippets, run LINQ queries, and experiment with APIs without creating full projects. It functions as a lightweight scratchpad where you can execute expressions and scripts and inspect results immediately, speeding up development and learning.
Main features and language support
- Visual Basic, C#, and F# are all supported, so you can test code in the language you prefer.
- Execute queries, scripts, or one-off expressions without launching a full IDE or managing multiple projects.
- Reference NuGet packages and libraries on the fly to experiment with third-party APIs.
- Inspect results with formatted output and quick object visualizers, helpful for debugging and exploration.
- Use it for both simple, ad-hoc experiments and more elaborate scripting tasks.
Why it helps productivity
LINQPad eliminates the routine overhead associated with creating and switching between Visual Studio projects for quick tests. That reduces clutter in your workspace and lets you focus on the code you’re evaluating. Its immediacy and lightweight UI make it ideal for prototyping, learning new APIs, and verifying LINQ queries or small algorithm changes.
Alternatives to consider
- dotnet-script — a free tool for running C# scripts directly from the command line.
- Visual Studio Code with the C# extension — a flexible editor that can be extended into a scripting and debugging environment.
- ScriptCS — another option for experimenting with C# scripts in a minimal environment.
Tips for getting started
- Download and install LINQPad 6, then pick your preferred language in a new query.
- Add NuGet references when you need external libraries rather than creating a full project.
- Use the object dump and results windows to quickly inspect returned data and iterate on code.
- Keep common snippets in saved queries so you can reuse them during debugging or learning.
Final thoughts
For quick tests, interactive exploration, and LINQ development, LINQPad 6 offers a fast, focused workflow. It’s especially useful when you want immediate feedback without the overhead of a traditional IDE.
