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
