Which languages are supported by DirectX? Can directX program written in HLA? (high level assembly) or can i use c# with DirectX?

DirectX uses a COM interface. That exposes it to most modern languages. Not just C# and assembly, but also languages like python.


You can access it with HLA if you want. You'll need to manage stuff like vtables but that is part of the nature of assembly.

You can access it with C# through interop, although if that is your preferred language you are probably better with XNA which adds significant functionality.
