When my Property equivalent to Days is null in all my equivalent Product Class Objects, I get a 'System.NullReferenceException'. How do I avoid that Exception (i.e. without first explicitly (i.e. via a separate Statement) scanning Product Class Objects first to ensure at least one has a non-null Days Property)? Hoping for something like a Null Conditional Operator.

@Tom: Either add where product.Days != null first or add ?? Enumerable.Empty<T>(). I don't know how that would work with a query provider, though.
