Answer 1

Drop the S in front of the string literal.

It's possible that you need a newer book, the S prefix for strings was used for "Managed Extensions for C++" which has deprecated a long time ago.

Answer 2

The following was generated by the VS2015 App Wizard for a CLR console application:

// ConsoleApplication1.cpp : main project file.

#include "stdafx.h"

using namespace System;

int main(array<System::String ^> ^args)
{
    Console::WriteLine(L"Hello World");
    return 0;
}
