enum_with_abstract_member

'{0}' must have a method body because '{1}' is an enum.

The analyzer produces this diagnostic when a member of an enum is found that doesn't have a concrete implementation. Enums aren't allowed to contain abstract members.

The following code produces this diagnostic because m is an abstract method and E is an enum:

enum E {
  e;
​
  void m();
}

Provide an implementation for the member:

enum E {
  e;
​
  void m() {}
}
