Avalonia Enum UserControl Content Selection

GuiStateTemplate.cs

    class GuiStateTemplate : DataTemplate, IDataTemplate
    {
        [TypeConverter(typeof(EnumConverter))]
        public GuiState State { get; set; }

        bool IDataTemplate.Match(object data)
        {
            var enumVal = (GuiState)Enum.Parse(typeof(GuiState), data.ToString());
            var result = State == enumVal;
            Logging.Debug(string.Format("GuiStateTemplate Match: {0} == {1} ({2})", State, enumVal, result));
            return result;
        }
    }

MainWindow.xaml

      <UserControl Grid.Row="1">
        <UserControl.DataTemplates>
          <local:GuiStateTemplate State="Searching"><uc:SearchingControl/></local:GuiStateTemplate>
          <local:GuiStateTemplate State="Idle"><uc:IdleControl/></local:GuiStateTemplate>
        </UserControl.DataTemplates>
        <ContentControl Content="{Binding GuiState}"/>
      </UserControl>

I met a problem with this way that avalonia throw error like this:
Unable to find default constructor and no non-default one is specified.
