okay, long shot but: is there any way to pinvoke into objective-c without building a little translation layer .dylib?
I want to open a native file chooser dialog on MacOS (presumably NSOpenPanel) from a Unity game (on Steam), without needing to build/ship a dylib shim.

Yeah, that one would be high on the blocklist:
- Dynamic C#
- PInvoke
- kernell32.dll
- LoadLibrary method
Lots of flags there. When possible, I try to do a hybrid module instead and ship the C#-bits as a DLL file. Does the same thing, but not under the "PowerShell is evil" filters.

I got it on windows (C# COM to create IFileOpenDialog) and linux (pinvoke into gtk3, which has a shim shipped by Steam for cross-distro support), and it'd be suuuper cool to also have a "pure" C# solution for macos, but I'm losing hope

There was apparently an update to user32.dll recently in #Win11 and you can no longer forward the wm_input message to a different process because you will get an invalid handle error if you try to read from it. I have no idea if that was intentional but it broke things. #Windows #Pinvoke

Subclassing in this context means “replacing a window function (WinProc) with your own”. It’s surprisingly simple to do and use, once you understand the general design. But that requires dealing with pointers, 32 and 64-bit adresses, via PInvoke and Marshal namespaces.
