'type' : illegal dereference of a handle type

The compiler detected an illegal dereference of a handle type. You can dereference a handle type and assign it to a reference. For more information, see Tracking Reference Operator.

Example

The following sample generates C3288.

// C3288.cpp
// compile with: /clr
ref class R {};
int main() {
   *(System::Object^) nullptr;   // C3288

// OK
   (System::Object^) nullptr;   // OK
   R^ r;
   R% pr = *r;
}
