This question is related, but NOT a duplicate: How to install XNA game studio on Visual Studio 2012?
I read the above mentioned post, and have got xna projects opening, but I now have a problem.
Some of the references to the XNA framework aren't found:
Microsoft.Xna.Framework.Avatar
Microsoft.Xna.Framework.GamerServices
Microsoft.Xna.Framework.Net
Microsoft.Xna.Framework.Storage
Microsoft.Xna.Framework.Video
And all references to Microsoft.Xna.Framework.Content.Pipeline
Without these, I can't compile or run any games that I've made. I can't find the dll that contains these, or where I should put them.

UPDATE: March 3, 2014
Use the download for VS2012 and VS2013 at this link: https://msxna.codeplex.com/releases. I have no idea of the legality on that project (the developers seem to have decompiled XNA), but it did help me ease the pain of needing VS2010 in order to utilize the content pipeline.
