Has PostEditChangeProperty changed?

Greetings -
I’m working with version UE 4.18.1 and am encountering the same problem myself.

I tried including “Object.h” but to no avail.
Does anyone know which header to include in order to get this working?

#include "CoreMinimal.h"
#include "GameFramework/Actor.h"
#include "Object.h"
#include "My_Actor.generated.h"

UCLASS()
class MYActorProject My_Actor : public AActor
{
	GENERATED_BODY()
	
public:	
	// Sets default values for this actor's properties
	My_Actor();
...
        // Visual Studio Can't find "PostEditChangeProperty"
	virtual void PostEditChangeProperty(struct FPropertyChangeEvent&) override;
...
};
