Windows Phone DateTime exception

I'm currently working on localizing a Windows Phone application but I've started getting an index out of range exception on DateTime.Now.ToString().

I've tried changing the timezone of my computer but the error persists.

I'm unsure of what caused this problem or what to do to fix it.

Any ideas? Thanks in advance!

My app was localized and I did not use Culture Codes in the correct format, for example, I would use en instead of en-US or fr instead of fr-FR.

Once I became specific as explained above, the DateTime.Now.ToString() began to work as expected.

This can happen if the date is invalid for the current culture's calendar.

According to the MSDN documentation: The ToString() method returns the string representation of the date and time in the calendar used by the current culture. If the value of the current DateTime instance is earlier than Calendar.MinSupportedDateTime or later than Calendar.MaxSupportedDateTime, the method throws an ArgumentOutOfRangeException.

What is the current culture in your app?
