Mono is an open source implementation of Microsoft's .NET Framework based on the ECMA standards for C# and the Common Language Runtime, including a JIT/AOT runtime, garbage collector, and C# compiler. It enables cross-platform .NET application development and embedding, though the project has been superseded by .NET and stewardship is moving to WineHQ.
Use cases
- run .NET applications on Linux or macOS
- embed a C# scripting runtime in a C/C++ application
- build cross-platform mobile apps with Xamarin
- compile C# code with the mcs compiler
- run ASP.NET applications outside Windows
- use ahead-of-time compilation for constrained platforms
When to choose
- you must run legacy .NET/Mono applications on non-Windows platforms
- you embed a managed scripting runtime in a native application
- you maintain an existing Xamarin or Mono-based codebase
When to avoid
- you are starting a new .NET project - use modern .NET instead
- you need the latest C# language features or .NET APIs
- you need long-term vendor support - the project is in maintenance with stewardship moving to WineHQ
