I have a desktop pc running Windows 7 and I have Visual Studio 2013 Ultimate edition.
I have never really tried creating apps for Windows Phone 8 or now the new Windows Phone 8.1 that has cortana on it.
The last time I created app for windows phone was Windows Phone 7 and I used Visual Studio 2010 running on Windows 7 for those.
To create apps for Windows Phone 8.1 do I need Windows 8 operating system?
Can I use Windows 7 and Visual Studio 2013 Ultimate as I have now?
Reason, I ask is because, I was just wondering if I need to buy a new computer that has Windows 8 on it to create windows 8.1 phone apps.
