How to write assembly?

Hello, i have asked this again but i don’t took any answer,

So im asking unity3d team, can i write assembly parts using C# in unity3d? for now im just writing assembly parts in C++, i export functions as DLL and then i call them from c#, well, that way is tiring and im looking for way to write direct asm.

Any way?

*Soz for my bad english.

No, C# is a managed language.
