Hi,
Thanks for your post.
This document is a good guidance for your reference about Cross-Platform Development in Visual Studio
https://msdn.microsoft.com/en-us/library/dn771552.aspx
In addition, you'd better use VS2015 Community instead of using Express version, it's also a free version of VS 2015 and the function is better than Express version.
Best Regards,
