DateTime is a ValueKind, so comparing it with null isn't very useful (it'll always not be null).
If your LINQ query doesn't find any rows, then FirstOrDefault() will return a default instance of the requested data type (DateTime, in this case).
There's a clue in the name Wink | ;)
If you want to know if you found any rows or not, either test the query first (e.g. Any()) before evaluating First(), or compare the returned value with the default DateTime value (DateTime.MinValue, IIRC). If you do that however, you won't be able to tell the difference between no rows, and rows where the first had the minimum datetime value.
