'<eventname>' implicitly defines '<membername>', which conflicts with a member implicitly declated in <type> '<typename>'
The name of a type member conflicts with the name of a member implicitly created for an event. Events implicitly create several variables. For example, the declaration Event X implicitly declares the names XEventHandler, XEvent, add_X, and remove_X.

To correct this error
Rename the explicitly declared member to remove the naming conflict.
