[Mono-winforms-list] WinForms Apps Crash on Mac OS X

[Justin Holewinski]

I'm having an issue with WinForms on Mac OS X 10.6.  WinForms apps used to
work, but all of a sudden they all crash on start-up.  Even trivial WinForms
apps crash now.  My first thought was the 10.6 upgrade, but I haven't read
of any Mono incompatibilities affecting WinForms.  I've tried uninstalling
and reinstalling Mono, including getting rid of the ~/.mono directory, but
no luck.  I am using the Mono .dmg image, version 2.4.2.3.

I read some older threads regarding font issues and needing X11, but X11 is
installed.  I use it everyday.


Test1.cs:

using System;
using System.Windows.Forms;

namespace test
{
  class Test
  {
    [STAThread]
    public static void Main(string[] args)
    {
      Form f = new Form();

      f.Show();

      Application.Run(f);
    }
  }
}


Crash:

acheron:winforms jholewinski$ mono Test1.exe
