CS2ASM is unmaintained and development is now going towards NativeCIL.
CS2ASM is a compiler which translates C# code into x86 assembly.
By using this compiler, you may create your own operating system using any language that compiles to CIL.
CS2ASM -a<address> -c<amd64> -f<bin,elf> -t<none,iso> -o<output> <input>
For example:
./CS2ASM -a0x100000 -camd64 -felf -tiso -ooutput.iso ConsoleApp1.dll
You can now try to run on bare metal, or via QEMU:
qemu-system-x86_64 -cdrom output.iso -cpu max -m 1G -enable-kvm -serial stdio
You need to have LLVM on your PATH to execute the ELF linker, LLD!
Be sure to remove the -enable-kvm argument if you're not on Linux!
CS2ASM includes a (very incomplete) version of the .NET core library.
CS2ASM also includes a neat System.Platform.Amd64 namespace where simple drivers reside.
For the sake of simplicity, an example operating system that uses the System.Platform.Amd64 namespace has been included.
CS2ASM is not IL2CPU!
Currently, only the AMD64 platform is supported.
