When an event declaration includes a
static modifier, the event is said to be a static event. When no

An instance event is associated with a given instance of a class, and this instance can be accessed as
this (Section 7.5.7) in the accessors of that event.
When an event is referenced in a member-access (Section 7.5.4) of the form
M is a static event,
E must denote a type containing
M, and if
M is an instance event,
E must denote an instance of a type containing
The differences between static and instance members are discussed further in Section 10.2.5.
