Error 1 The type 'Timeline.Controls.WorkspaceRegion' cannot be used as type parameter 'TEventArgs' in the generic type or method 'System.EventHandler<TEventArgs>'. There is no implicit reference conversion from 'Timeline.Controls.WorkspaceRegion' to 'System.EventArgs'. C:\Users\Ken\Downloads\timeline-73083\Timeline.Controls.Workspace\Controls\Workspace\Workspace.cs 32

Any reference to a generic handler such as:
public event EventHandler<WorkspaceRegion> RegionRegistered;
or
public event EventHandler<object> SomeOtherGenericHandler

raises the above compiler error. I am not sure how you have your environment configured that allows you to create an eventhandler with something other than a type that inherits EventArgs. I researched the issue and can't find a work around other than wrapping each of those handlers in a class that inherits EventArgs
