Answer 1

The pattern of LongDate for Spanish (Mexico) is

ffffdd, dd' de 'MMMM' de 'yyyy

according to Thread.CurrentThread.CurrentCulture.DateTimeFormat.LongDatePattern. I guess you just have to manually convert the initial letters of the day and month to uppercase or you can use Thread.CurrentThread.CurrentCulture.TextInfo.ToTitleCase and then replace "De" with "de".
