[Mono-osx] Mono 2.6 and Windows.Forms on MacOSX

After extensive research in how best to bring our C# application from
Windows to Mac we deemed the only viable solution was to write the UI in
native Cocoa. The UI embeds Mono and using mobjc/mcocoa the C# classes
expose the core business logic. Yes some code is written twice. This
overhead is well worth the cost of having a native looking UI on Windows and
Many similarities exist in a UI but it is the details that make an app feel
natural. Given that most Mac users are fanatics, especially in our user
base, having a sub-standard UI was not an option.
The theory of reusing a Windows Form application out of the box sounds
good... however in practice the end result will not behave like a 100%
native Mac application. That is not an acceptable option in my mind.
It is the same concept for MonoTouch. They did not reinvent how iPhone apps
are rendered. They are using the native tools which provides an accurate UI
for the end user.
