Traditionally, when we use SQL string to done some work, we have to close the sql connection before the page being closed, I was wondering if I use Linq to do the data operations do I still need to close the connection manually?

This is very similar to (but not quite a duplicate of) this question.
LINQ to SQL will open and close connections when it needs to – you don’t really have to dispose of the DataContext. However, there are times when you can ‘trick’ the context into leaving a connection open when you shouldn’t – I personally like to dispose of it as a matter of course. See my answer to the other question for a bit more detail from Matt Warren of the LINQ to SQL team.
I don’t know about the Entity Framework, however.
