Error C1083: Cannot open precompiled header file

Error C1083: Cannot open precompiled header file:'Debug\(What I named the file).pch

I can't compile this due to the error listed. I usually don't use this template for writing so I'm not familiar with it. I don't see how a header file can be missing if it was there when I choose new project then click clr under visual c++ then clr console application.

Code:

#include "stdafx.h"

using namespace System;

enum class Months {January=1, February, March, April, May, June, July, August, Semptember, October, November, December};

int main(array<System::String ^> ^args)
{
	Months::month = Months::January;
	int value = safe_cast<int>(month);
	for(int x=1; x<13; x++){
		Console::WriteLine(L"The numerical value of {0} is {1}", month, value);
		month++;
	}
	
    return 0;
}

And what is this? Your code?
