[Mono-dev] Patches for mono-winforms

Sun Jun 17 20:24:32 UTC 2012

Hah. To run the application with Mono on Windows, you should use the Mono
command prompt, and run the application using the "mono myapp.exe" command.
The default window icon is different, which will confirm the application is
run with Mono.
For what it's worth, P/Invokes should work with Mono on Windows. So if you
have to use P/Invokes, maybe you shouldn't check with framework the
application is running on, but which OS you're on.

"And re: getting bug fixes accepted, and WinForms not being a priority for
the Mono project...what about the bug fix for GetFileSystemEntries() I
posted a week ago?  That's not WinForms, and I haven't heard a peep about
it."

I don't know. I'm not on the Mono team, and only deal with WinForms.
