Do I have to close the SQL Connection manually if I use Linq?

Question

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 opera

Answer 1

In code you need not open and close connections. However, IMO a LinqDataContext should be treated as a resource like SqlConnection or SqlCommand and should be a part of the using block so that you dispose it when not using. Even though I have read on MSDN that this is not necessary but it is a good practice.
