New Project, C++ console application cannot compile

While this doesn't answer your question, you do not need to add using namespace for every namespace you invoke. In fact, by doing so you're undermining the very reason why these namespaces have been introduced in the first place: avoiding the cluttering of the global namespace.

Without the using statement you can still access individual symbols just by adding the name of the namespace as a prefix like this:

std::cout << "hello" << std::endl;

You can even inject singular objects or types from other namespaces into your own if you use them often:

#include <io>
typedef std::ostream ostream; // creates 'ostream' as a symbol in global namespace
ostream& cout(std::cout); // creates cout as a reference to std::cout

void hello() {
    cout << "hello" << std::endl; // uses ::cout defined above
}

I'm not saying you shouldn't take advantage of the using statement ever, I just think it's a bad idea to manipulate your IDE into adding it into every project!

Besides, adding this into your main.cpp file doesn't help for other cpp files. If you really want this to affect all files in your project, add it to stdafx.h instead.

Answering follow-up Question (after [EDIT]):

Using cout required std and iostream header:

#include <iostream>
using namespace std;

//...</iostream>

You could try to modify
the root.cpp file in your VC\..\templates\.. directory :)
