Wine doesn't ship a single DLL from the Windows distribution, as that would be illegal and get the project killed for good.
Mono does not
use the Windows API, it
implements the .NET libraries, and that's the bulk of the Mono source tree; just like the DLLs are the bulk of the Wine source tree. They're effectively the same kind of project except one executes PE files that use the win32/win64 API and the other CLI, CIL, CLR (or whatever the hell they're called) files using the .NET framework APIs.
