Graph::BeginUpdate Method (Object^, String^, UndoOption)
Visual Studio 2015
Starts a batch mode update on the Graph (which is more efficient). You must call the Complete() method on the returned GraphTransactionScope, otherwise your changes will be rolled back. The usual pattern is to use this in a using block so that if an exception is thrown the changes are automatically rolled back.
