ForEachEnumerator.Update Method (String)
This method updates the old package XML with the new package XML if CanUpdate is set to true.
Assembly: Microsoft.SqlServer.ManagedDTS (in Microsoft.SqlServer.ManagedDTS.dll)
The runtime calls CanUpdate on new objects and passes in the GUID of the old object. If the new object can update the old object, the old object is passed to the new one through the method, where the XML is changed.
By default, all extensible objects implement CanUpdate to return false and implement the method to do nothing on the XML it is given in its parameters.
