- <summary>
- ObservableAsPropertyHelper is a class to help ViewModels implement
- "output properties", that is, a property that is backed by an
- Observable. The property will be read-only, but will still fire change
- notifications. This class can be created directly, but is more often created via the
- ToProperty and ObservableToProperty extension methods.
-
- This class is also an Observable itself, so that output properties can
- be chained - for example a "Path" property and a chained
- "PathFileNameOnly" property.
