Answer 1

That's the beauty of Linq that every query returns an IQueryable so you can defer getting the final result until you really decided what you want. On the other word you can execute a query over another query :) So in order to get the real data out of a query you should execute a command over it that actually returns what you want. In your case since you are expecting your query to return only one value any methods like "FirstOrDefault","Single" or "First" will do the trick
