General

The Xbox 360 Software Development Kit Porter does exactly what the name implies, and that is allowing you to upgrade the SDK to another Visual Studio version, currently ranging from 2012 to 2015. It is recommended you have the Ultimate edition of both Visual Studio 2010 and the other version you wish to upgrade to. If you are presented an error, that means you're missing a certain folder. The most common is below, which you can simply create to bypass the error:

C:\Program Files\Microsoft Visual Studio 10.0\Common7\IDE\Extensions\Microsoft\RiaTools

C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE\Extensions\Microsoft\RiaTools

You'd create one of those two depending on your architecture.
