Compiler Error C3755

'delegate': a delegate may not be defined

Remarks

A delegate (C++ Component Extensions) can be declared but not defined.

Examples

The following example generates C3755.

// C3755.cpp
// compile with: /clr /c
delegate void MyDel() {};   // C3755

C3755 can also occur if you attempt to create a delegate template. The following example generates C3755.

// C3755_b.cpp
// compile with: /clr /c
ref struct R {
   template<class T>
   delegate void D(int) {}   // C3755
};
