This documents some features that are not strictly required to be implemented by the interfaces and therefore may go unnoticed.
To implement this feature available through the property context button, the interface ICanNavigateToSource is implemented on IPropertyInfo instances. It provides an availability query through bool CanNavigateToSource (IObjectEditor); and a signal through NavigateToSource (IObjectEditor). The integrator will route the signal from NavigateToSource to whatever mechanism they have to handle requests to open files and move to lines.
The name of an object (field name, x:Name, etc) holds a special place within the UI for the property editor. While you can certainly treat this as a normal string property, there is a special interface that elevates this property to the top level. If you implement this property you should not report it through the normal IObjectEditor.Properties.
To support, implement INameableObject on your IObjectEditor. The API is a simple string get/set in GetNameAsync() and SetNameAsync (string).
The implementing platform can specify property categories that should be opened by default (otherwise they are all collapsed). In TargetPlatform.AutoExpandGroups, add the category names that should be expanded by default.
