I don't know much about C#, but here are some thoughts:
The ONLY purpose of the pm_dll DLL is to attempt to close open MIDI input ports when the program exits. (DLL's get control when a program exits normally, where "normal" includes calling exit() and typing control-C, but "normal" does not include instruction-level traps such as attempting to read data through a NULL pointer.)
You can eliminate this additional protection using a compile option so that PortMidi will not need or initialize the DLL.
There might be other mechanisms in C# to install handlers for runtime errors and exit clean-up. If so, it might be desirable to use them instead of pm_dll.
If a program leaves a MIDI input port open under Win32, the operating system is likely to crash (!), so this is a serious operating system bug. The "correct" solution is for MS to fix the gaping hole in Win32 security, but meanwhile, anything we can do to protect the system is worth some attention, hence the clumsy but often effective pm_dll.
