Include an 'InterfaceDefinition' build action for MonoTouch Binding Project
A 'MonoTouch Library Project' has an 'InterfaceDefinition' build action that xib files are marked with. This embeds them into the resultant dll using the /res option of smcs. However there is no matching build action when creating a 'MonoTouch Binding Project'. This would be useful when wrapping Objective-C 'View' libraries - the ViewController's are within the static *.a library, and their corresponding nibs are embedded within the wrapper MonoTouch dll.
Same applies to content items (e.g. images referenced by the xibs). Although the Binding Project does have a 'Content' build action, it doesn't get included in the resultant dll's embedded resources with the special ''__monotouch_content_' prefix and so is not found when compiling the application that links to this binding library.
