[Mono-list] Help for porting: VC# 2008 express binaries crashing when run by mono

--debug is generally much more helpful, and *much much much* less verbose, than -v.  Try it and see you get any errors reported on the console then.

IIRC when running a winexe assembly (e.g. a WinForms app) the program will detach from the console and so can't output any errors.  --debug keeps the attachment.  (Or briefly change the build type to "exe" in your VS solution).
