I have this query:

int maxShoeSize = Workers
    .Where(x => x.CompanyId == 8)
    .Max(x => x.ShoeSize);

What will be in maxShoeSize if company 8 has no workers at all?

UPDATE:
How can I change the query in order to get 0 and not an exception?

int maxShoeSize = Workers.Where(x => x.CompanyId == 8)
                         .Select(x => x.ShoeSize)
                         .DefaultIfEmpty(0)
                         .Max();

The zero in DefaultIfEmpty is not necessary.
