C# Shell .NET IDE

A complete, C# / .NET IDE that runs on your Android device — no server, no emulator, no PC required. Write, compile, and run real .NET assemblies with the CoreCLR, right where you're standing.

[Editor]

- C# 12+ editor with syntax highlighting and Roslyn-powered IntelliSense

- Real-time error checking as you type, plus a code-actions lightbulb with quick fixes and refactorings

- Find & replace, multiple editor themes, adjustable font size, invisible characters

- NuGet package management, with IntelliSense that refreshes automatically

[Run, debug, test]

- Console apps and full .NET MAUI (GUI) apps

- Step-through debugger with a live object inspector

- Built-in xUnit test runner and Test Explorer

- Export a runnable assembly and pin a home-screen launcher shortcut to it

- Build, sign, and install an APK of the app you just wrote

[Projects & source control]

- Multi-project solutions (.sln / .slnx) with a Solution Explorer

- Dual-pane file manager

- Built-in Git: clone, commit, browse history, and a syntax-highlighted side-by-side diff viewer

[AI coding assistant]

- Chat with an AI assistant that can read, search, and edit your files, run your code, and call tools through MCP

- Choose your backend: an on-device model, Ollama, OpenRouter, or any OpenAI-compatible API

- Connect your own MCP servers for extra tools

[Learn]

- Built-in code examples and practice tasks

[Free with optional Premium]

The app is free to use and shows ads. A one-time Premium purchase removes them.

[Runtime Note]

This is not Visual Studio or Windows.

This app runs on Android and is subject to some of the OS limitations.

Hence Windows-only technologies can't work on Android at all.

This includes WPF, UWP, Windows Forms, the Windows API, and all libraries dependent on them.

Your device requires free storage of at least 1 GB to properly install, even though the app takes up only about 350MB.

[System requirements]

This application runs everything locally, so it may not run well on devices with, for example, 1 GB of RAM and a 1.0 GHz CPU with 4 cores.

2 GB RAM and 2 GHz x 4 should run well.
