VB.NET and the CLR in general don’t support mixing assembly-code with CIL (it’s possible, but let’s just assume it isn’t) in the same assembly (note that “an assembly” is the name given to a .NET executable and does not refer to “assembly code”, it’s confusing, I know).
You’ll want to do this via interop. You’ll want to compile your assembly instructions into their own native Windows DLL file, then export those functions (your assembler/linker will come with instructions on how to do this), then from within VB.NET define a static class (“Module”) that has DllImport statements for each exported function from your DLL. Then it’s just a matter of calling those functions.
Type conversion (“Marshalling”) to native is handled for you by the CLR.
