However, using these methods does provide one useful benefit: The dialog boxes always have the “owner” set to the UDI Wizard, which ensures that the dialog box is grouped correctly with the main window.

You can use dependency injection to obtain a pointer to this interface using code like this in your class:


public IMessageBoxService MessageBoxes { get; set; }
