Cosmos (C# Open Source Managed Operating System)
Cosmos is an operating system "construction kit", built from the ground up around the IL2CPU compiler in C# and our home-brewed language called X#.
It's current stage is only usable for academic work. Some day Cosmos will be ready for production work, but to reach that stage we need more developers. Specifically, we need a few more low-level developers to help the few core developers who are currently overwhelmed with work.
Cosmos is available in two flavors:
- User Kit - The User Kit is used to develop your operating system in Visual Studio. If you are new to Cosmos, you can learn here. Latest Release available.
- Development Kit (Devkit) - The Development Kit is the full Cosmos source and build tools. If you need to modify the Cosmos core functions or modify built-in drivers, boot, compiler, etc.. you will need to use Development Kit. Tutorial for building the Development Kit - Building from the source is easy with our automated builder.
