Hey, how to compile CSharp to machine code?

[SiliconOS]

I want to build a 64bit Graphical CSharp OS, named Silicon OS(such as my name).
I want to know:
How can I compile C Sharp code to machine code?
How can CSharp to operate filesystem(FAT32, NTFS)?

I'm a Chinese.Your advice are most welcome!

Welcome! That's an ambitious project. I suggest reading this post for information that will help you.

How can I compile C Sharp code to machine code?

Take a look at the C# OS projects listed on the wiki. Those should give you some ideas for how to do it.

How can CSharp to operate filesystem(FAT32, NTFS)?

It works the same way with any language. (But there's no official NTFS documentation, so NTFS will be difficult.)

First, I need a tool to compile CS to native machine code.
Next, the OS need a bootloader, so I'm studying C and C++.
The C# library will be more difficult.

Which doesn't exists. There used to be one, but disappeared with tysos. Good luck with webarchive and latest C# versions...

Next, the OS need a bootloader, so I'm studying C and C++.

Try BOOTBOOT, it will load your x86_64 kernel no matter what language it was compiled from (if you can compile native machine code from C#, that is).

The C# library will be more difficult.

But a must. Languages need run-time support libraries, that's how they work. Some languages require less, others more. In general you can say that the most "advanced" a language is, the bigger run-time it requires and harder to use it for bare-metal development (like RTTI in C++ for example). C is the preferred choice because you can use it without any run-time whatsoever (so called freestanding mode), and it compiles to native machine code directly (not an interpreted language like C# and Java).

Have you looked at FlingOS? They have a C# AOT compiler that turns C# IL to machine language.

Tysos moved to GitHub. The CIL compiler is also on GitHub.

Would you care to update our wiki with this info? Thanks a lot!
