NetPad

A cross-platform C# editor and playground.

Get Started

• Prototyping and Testing: Quickly prototype and test code snippets before incorporating them into your projects.
• Data Visualization: Visualize data interactively for better insights and analysis.
• Database Queries: Query databases using LINQ or SQL effortlessly.
• Learn and Experiment: Experiment with new C# features or start learning C# in an intuitive and accessible environment.

Motivation

This project aims to create an open-source, cross-platform alternative to LINQPad. NetPad can run as a native desktop app or in a web browser, and aims to cover the most commonly used features while introducing new ones of its own.

Official Installers

NetPad comes in 2 variants:

• Electron: The current stable package. Installers start with netpad
• Native (vNext): Uses a native desktop shell built with Tauri instead of Electron, resulting in a lighter package that uses fewer system resources. Installers start with netpad_vnext

Both variants have the same features and are equally maintained. The Native (vNext) variant is planned to become the main package, at which point the Electron variant may be deprecated.

[!NOTE] On macOS see this if you have trouble opening NetPad.
