Answer by Giorgi for How to add new line in FormattedString

You can use Environment.NewLine to move text to the next line like this:

   public FormattedString FormattedDescription   {       get       {           return new FormattedString           {                Spans = {                            new Span { Text = RoleName, FontSize = 16, FontAttributes = FontAttributes.Bold },                            new Span { Text = Environment.NewLine, FontSize = 16 },                            new Span { Text = "/ "+ ProjectRoleID +"/ "+Part +"/ "+Gender +"/ "+ AgeRange},                        }           };       }       set { }     }
