I have two questions:
I have both Visual Studio 2012 SP4 and Visual Studio 2013 SP1 on my machine:
1. In the document http://msdn.microsoft.com/en-us/library/office/fp161179(v=office.15).aspx there is a link to Downloads page of the Apps for Office and SharePoint Developer Center and choosing the link for the web-based platform installer (WebPI) that installs the tools and assemblies that you will need to develop apps for SharePoint. for installing the Office Developer Tools for Visual Studio 2012; however on this page I don't see any link to the WebPi for VST2012, only a download for VST2013? (when clicking What are Apps for SharePoint 2013 -- Get started)!?
2. When developing with Visual Studio 2013, what extra do I need to install (besides the standard installation of Visual Studio 2013 Professional) for developing/publishing SharePoint 2013 Online Apps: is Office Developers Tools for Visual Studio 2013 all I need?
Thanks.
