title: Platform update - Move from RC1 to RC2 - not application
body: <p>my question is not about migrating projects but about the platform. I I have on a win10 box VS 2k15, MS ASP.Net 5 RC1 Update 1 with .Net Framework 4.5, 4.5.1, 4.5.2, 4.6 and 4.6.1 (Multi-Targeting Pack, Targeting Pack)
  I read at <a href="https://www.microsoft.com/net/core#windows" rel="nofollow">https://www.microsoft.com/net/core#windows</a> 
  <em>Remove all previous versions of .NET Core from your system by using Add/Remove programs</em>
  So should I remove all of the above aa you can notice in the snapshot hereunder</p>
