Unable to find enum type for static reference in WPF

I'm trying to bind an enum to a radio button in WPF (Inspired by this answer), but I have trouble finding the enum type for the converter parameter: The enum is defined in the following way ``` namespace Application.Models { public class Enums { public enum MySelections { one, two ,three }; public MySelections CurrentSelection; ... } } ``` I am trying to bind now the checkbox like this (The data context is assumed to be correct and the value converter implemented:) ``` <Window x:Class="Application.MainWindow" .... xnlns:models="clr-namespace:Application.Models" > ... <RadioButton Content="One" IsChecked="{Binding Path=CurrentSelection, Converter={StaticResource EnumToBooleanConverter}, ConverterParameter={x:Static models:Enums.MySelections.one}}" /> ... ``` The problem lies with `{x:Static models:Enums.MySelections.one}` which constantly throws the error that the type `models:Enums.MySelections` could not be found. How can I find my enum type?
