Events are locked?
Events declared in a class have their + = and-= access automatically locked via a lock (this) to make them thread safe (static events are locked on the typeof the class ). events declared in a struct do not have their + = and-= access automatically locked. A lock (this) for a struct wocould not work since you can only lock on a reference type expression.
