// Create an application and load the sample.
Application app = new Application();
Package pkg = app.LoadPackage(mySample, null);
Connections myConns = pkg.Connections;
// Show how many connections are in the package.
int myConnsCount = myConns.Count;
Console.WriteLine("The number of connections is: {0}", myConnsCount);
// Add an OLEDB connection manager.
ConnectionManager myConn = pkg.Connections.Add("OLEDB");
myConn.Name = "My OLEDB ConnectionManager";
myConn.ConnectionString = "Data Source=.;Initial Catalog=AdventureWorks;Provider=SQLOLEDB.1;Integrated Security=SSPI;Persist Security Info=False;Auto Translate=False;";
// Verify the addition of one connection manager.
