Not really asking a question. Just putting this out there because of lack of documentation.

In Umbraco 8. Getting expired date of content has been moved. Probably to better handle publishing of cultured content.

Anyways myContent.ExpireDate is removed. myContent is a type of IContent you get from the content service.

You can get the expiration by:

 var expiredate = myContent.ContentSchedule.FullSchedule.FirstOrDefault(a => a.Action == ContentScheduleAction.Expire).Date;

The contructor for ContentSchedule is

public ContentSchedule(string culture, DateTime date, ContentScheduleAction action) 

So you can also query by culture if need be.

You can see this thread for setting a expire date: https://our.umbraco.com/forum/using-umbraco-and-getting-started/99648-programmatically-set-unpublish-date
