## What it is
MonoDevelop is a cross-platform integrated development environment for .NET and Mono, built with C# and Gtk#, supporting C#, F#, and Visual Basic .NET with debugging, code completion, and a GTK# visual designer. It served as the foundation for Visual Studio for Mac, but the project has been archived and unmaintained since January 2020.

## Use cases
- write C# applications on Linux
- cross-platform .NET IDE
- debug Mono applications
- design GTK# user interfaces
- develop ASP.NET web projects
- port Visual Studio .NET projects to Linux and macOS

## When to choose
- you need an open-source IDE for Mono/.NET development on Linux
- you want to study or fork the codebase that became Visual Studio for Mac
- you maintain legacy Mono or GTK# projects

## When to avoid
- you need a maintained IDE with current .NET support
- you want modern C# language features and tooling
- starting a new project today - use Visual Studio, VS Code, or JetBrains Rider instead

## Facets
