SyntaxEditor: NullReferenceException is thrown when using LineHighlightTagger

When using LineHighlightTagger a NullReferenceException is thrown. To workaround this exception, you can add a custom TextFormatDefinition object to the TextFormatDefinitions collection of the RadSyntaxEditor.

this.syntaxEditor.TextFormatDefinitions.AddLast(LineHighlightTagger.LineHighlightFormatDefinition, new TextFormatDefinition(new Telerik.Windows.Controls.SyntaxEditor.UI.Pen(new SolidColorBrush(Colors.Gray), new Thickness(1))));
