DataContext Constructor (IDbConnection)
Initializes a new instance of the DataContext class by referencing the connection used by the .NET Framework.
Assembly: System.Data.Linq (in System.Data.Linq.dll)
A DataContext opens and closes a database connection as needed if you provide a closed connection or a connection string. In general, you should never have to call Dispose on a DataContext. If you provide an open connection, the DataContext will not close it. Therefore, do not instantiate a DataContext with an open connection unless you have a good reason to do this. In a System.Transactions transaction, a DataContext will not open or close a connection to avoid promotion.
