Compiler Error C3797

'override': event declaration cannot have override specifier (should be placed on event add/remove/raise methods instead)

You cannot override a trivial event (an event without explicitly defined accessor methods) with another trivial event. The overriding event must define its behavior with accessor functions.

For more information, see event (Visual C++).

The following sample generates C3797.

// C3797.cpp
// compile with: /clr /c
delegate void MyDel();

ref class Class1 {
   virtual event MyDel ^ E;

ref class Class2 : public Class1 {
   virtual event MyDel ^ E override;   // C3797

// OK
ref class Class3 : public Class1 {
   virtual event MyDel ^ E {
      void add(MyDel ^ d) override {}
      void remove(MyDel ^ d) override {}
