[Mono-osx] MonoMac: ClassHandle issue

[Miguel de Icaza]

Hello Duane,

    Are you referencing monomac.dll, or are you compiling all its source
code directly into your app?

    This problem happens if you try to put the MonoMac source code into your
project, instead of keeping it as a separate assembly.
