<hr/>

Cosmos (C# Open Source Managed Operating System) is an operating system development kit which uses .NET, alongside the custom IL2CPU compiler to convert (most) C# code into a working bare-metal OS.
Despite C# in the name, any .NET-based language can be used, which includes: VB.NET, IronPython, F# and more. Cosmos itself and its kernel routines are primarily written in C#, and thus the Cosmos name.

In a project, Cosmos can be thought of as a compiler and a sort-of standard library for a project. It gives the user access to often hard to find or otherwise difficult to understand tools.
