RetainStateProvider.AlwaysKeepExitedValues
An implementation of RetainStateProvider that is not backed by a RetainScope and is always set to keep exited values. This object is stateless and can be used to orphan a nested RetainScope while maintaining it in a state where the scope keeps all exited values.
