MOOS is a hobby x64 operating system written in C# using .NET Native AOT compilation. It supports multithreading, SMP, USB, networking, and can run applications like DOOM, but is deprecated in favor of BootTo.NET.
Use cases
- write an operating system in C#
- run C# code on bare metal
- learn OS development with .NET NativeAOT
- boot a managed-code kernel on x64 hardware
- experiment with multithreading and SMP in a hobby OS
When to choose
- you want to study or fork a C# bare-metal OS
- you're interested in NativeAOT/CoreRT compiled kernels
When to avoid
- you need a production or stable operating system
- you want active development - the project is archived and deprecated in favor of BootTo.NET
- you need IPv6, USB hubs, or exception handling
