Am I misunderstanding LINQ to SQL .AsEnumerable()?

Question

Consider this code:

var query = db.Table
              .Where(t => SomeCondition(t))
              .AsEnumerable();

int recordCount = query.Count();
int

Well, you are on the right track. The problem is that an IQueryable (what the statement is before the AsEnumerable call) is also an IEnumerable, so that call is, in effect, a nop. It will require forcing it to a specific in-memory data structure (e.g., ToList()) to force the query.
