Hi,
The error you experience on your side is due to the fact that the Visual Studio integration of Data Access was deprecated in Data Access Q2 2015 (the
Linq Data Source Configuration wizard includig). Following the tutorial you mentioned will allow you to configure declaratively the OpenAccessLinqDataSource control, but it does not enable the wizard. Hiding the entry point to the deprecated wizard is logged on our side, but at the time present, I am unable to provide you with a specific date when the fix should be released.
I am sorry for the inconvenience caused.
Regards,
Doroteya
