LINQPad 5 for Windows

Tool snapshot

LINQPad 5 is a compact utility for .NET developers that makes it easy to try out C#, F#, and VB code snippets without creating a full Visual Studio project. It provides a quick, focused environment for experimenting with LINQ queries or other short pieces of code, letting you iterate fast and validate ideas without the setup overhead of a traditional IDE.

Core capabilities

• Acts as a lightweight substitute for multi-project console solutions and heavier development environments
• Lets you execute LINQ expressions and arbitrary C#/F#/VB snippets on the fly
• Includes support for SQL-style queries alongside various .NET APIs
• Offers an approachable interface designed for incremental development and rapid prototyping

Why developers reach for it

LINQPad 5 speeds up testing and prototyping by removing clutter: you don’t need to manage solution files or extra projects just to try out a few lines of code. Its minimal setup and immediate feedback loop make it a practical choice when you want to validate logic, inspect results, or learn language features quickly.

Getting started

Download the free application, open a new query, pick the language you want (C#, F#, or VB), and start typing. The environment executes expressions directly so you can focus on experimenting rather than configuring projects.
