How do I get the latest date from a collection of objects using LINQ?

I have a list of objects and each object has a ExpirationDate property which is of type DateTime. I want to retrieve the latest date in the list. Is there an elegant way of doing that through LINQ?

Something like:

DateTime latestDate =  myCollection.Where(r=>r.ExpirationDate.HasValue).MaxDate(r=>r.ExpirationDate.Value);
