Event Tutorial does not work.
In the tutorial Events for Developers in page docs.sitefinity.com/for-developers-events says that we need to reference the folowing:
using Telerik.Sitefinity.Events.Model;
using Telerik.Sitefinity.GenericContent.Model;
using Telerik.Sitefinity.Modules.Events;
using Telerik.Sitefinity.Workflow;
But in Visual Studio the Telerik.Sitefinity.Events.Model never recognizes.
For all who faces the same question in Sitefinity 8.2 the correct way to use the Telerik.Sitefinity.Events.Model and Telerik.Sitefinity.Modules.Events is to reference the Telerik.Sitefinity.ContentModules.dll inside project.
