• [nitpick] The enum member 'ObservableCollectionT' can be ambiguous; consider renaming it to a more descriptive name such as 'ObservableCollection'.

ObservableCollectionT,

• [nitpick] The property name 'Thickness' is ambiguous given that it represents a numerical value for PeekAreaInsets; consider renaming it to something more descriptive like 'PeekThickness'.

public int Thickness

• The AutomationId 'EmptViewNone' appears to have a typo; consider renaming it to 'EmptyViewNone' for consistency with the naming convention.

<RadioButton x:Name="EmptyViewNone" Content="None" IsChecked="True" GroupName="EmptyView" FontSize="11" CheckedChanged="OnEmptyViewChanged" AutomationId="EmptViewNone"/>
