Symptoms

I updated the K2 development system to K2 4.6.11 today and also our client installations. In K2 Studio the new event wizards show up, but not in Visual Studio (we opened existing projects). Any idea why this is the case? The client installations went through without any problems. Also on the server itself the new event wizards do not show up.

Resolution 

Refreshing the Toolbox in Visual Studio showed the new events. Unlike to the documentation they show up in the General section and not in the Event Wizards.
