LNK2019 unresolved external symbol DriverEntry referenced in function FxDriverEntryWorker

Question

I am getting error: LNK2019 unresolved external symbol DriverEntry referenced in function FxDriverEntryWorker

With my code: (The code is C++ Kernal mode Driver [Empty])

#include <ntdef.h>
#include <ntifs.h>
#include <ntddk.h>
#include <windef.h>
#include <ntstrsafe.h>
#include "driver.h"
#include "memory.h"
#include "hook.h"

extern "C" NTSTATUS EntryPoint(PDRIVER_OBJECT driver_obj, PUNICODE_STRING registry_path)
{
    UNREFERENCED_PARAMETER(driver_obj);
    UNREFERENCED_PARAMETER(registry_path);

    if (hook::call_kernel_function(&hook::hook_handler)) {
        DbgPrintEx(0, 0, "NtOpenCompositionSurfaceSectionInfo Function was hooked!\n");
        return STATUS_SUCCESS;
    }
    else {
        DbgPrintEx(0, 0, "Function hook failed\n");
        return STATUS_FAILED_DRIVER_ENTRY;
    }
}

I have tried rebuilding as different types,
