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

Its (relatively) easily to debug into Mono SWF code, its described at
http://www.mono-project.com/Guide:_Debugging_With_MWF.  In short when
compiling the app, replace the SWF reference to the MWF assembly -- which
needs to be *non*-StrongNamed or the real SWF assembly will be loaded at

Its a bit of a shame that the original app needs to be recompiled for this
to work.  It'd be great if Cecil could be used to remap the SWF reference at
runtime, in a wee app like:

   static void Main()
      // Choose the target WinForms app
      OpenFileDialog dlg = new OpenFileDialog();
      DialogResult rslt = dlg.ShowDialog();
      if (rslt != DialogResult.OK)
      String path = dlg.FileName;
      Assembly appOrig = Assembly.LoadFile(path);
      // Cecil magic!
      Assembly app = RemapSwfToMwf(appOrig);
      MethodInfo mi = app.EntryPoint;
      Object[] appArguments = CreateCommandLineArgs(mi);
      // Run!
      mi.Invoke(null, appArguments);

It would be great if someone would like to look at this. :-)

Also, any mention in Mono lists of MSFT code access should probably have a
wee note saying: don't use it if you might every want to contribute to Mono.
