Win32 does not exist

[Gavin-Williams]

We are starting a new project. But we can't get Win32 to be visible.

I've added the CSWin32 nuget package, I've added a NativeMethods file with 'GetModuleHandle'

But Win32 namespace doesn't exist.

public sealed class Window
{
    public uint Width {get; private set;}
    public uint Height {get; private set;}

    private readonly Windows.Win32.FreeLibrarySafeHandle HInstance;

    public Window()
    {
        HInstance = GetModuleHandle((string)null);
        if (HInstance.IsInvalid)
            throw new Exception("Window | GetModuleHandle / HInstance failed.");

    }
}

Don't worry, after getting back and opening the project up, it now works.
