AsaConnection class
Opens a connection to a database, using the previously-specified connection string.
void Open( )
IDbConnection.Open
The AsaConnection draws an open connection from the connection pool if one is available. Otherwise, it establishes a new connection to the data source.
If the AsaConnection goes out of scope, it is not closed. Therefore, you must explicitly close the connection by calling Close or Dispose.
