Why visual studio recognizes __asm {} but can't recognize assembly code?

Question

We can use stuff like this in visual studio:

__asm
{
    mov   x1,offset thunk_begin; 
    mov   x2,offset thunk_end;
}

But as quoted from here:

Since Visual Studio does not recognize assembly code, Visual Studio will have to be told what program to call to compile the assembly code.

I'm really confused.

Answer 1

That refers to standalone assembly source files, not inline asm, which is what your example is.
