Hi Nick Chance,
We try to support and provide both C# and VB.NET examples, help and articles without discriminating by any means on VB developers. The example you refer to is a mistake that we will resolve in future. We are currently working on improving our help that will feature C# as much as VB.NET code. I understand your dissatisfaction with our VB.NET support, but I can assure you that it will change pretty soon. Thank you for contacting us and we look forward to receiving other valuable feedback from you.
