When I installed MVC4 beta on a development PC, it had a template for SPA (Single Page Application). Today on a different PC with the same setup (VS2010 SP1, win7), I installed MVC4 RC but no longer is the SPA template available (see image). Any one else having this issue? or is this a documented change that I could not find?
Changes from ASP.NET MVC 4 Beta
The major changes from ASP.NET MVC 4 Beta in this release are summarized below:
Removed ASP.NET Single Page Application: ASP.NET Single Page Application (SPA) shipped with ASP.NET MVC 4 Beta as an early preview of the experience for building applications that include significant client-side interactions using JavaScript. SPA won’t ship with the final MVC 4 release, but will continue to evolve outside of the MVC 4 release. Check out the ASP.NET SPA home page for details.

P.S., Wow I am glad that I didn't use it for an app I build right now. I was considering it 3 months ago, but decided not to risk it because MS said that it is experimental.
You can get the SPA template in the Fall 2012 update. More information on the template here and here.
It`s very risky now
For example if you try to run it with System.json for serialization it runs well with WebApi and DBDATAContext methods but it`s impossible to use it with Entities relationship entity circular errors and so on. (There is a solution to change private access of method get, but would be too much work to have to change in all the access methos of all your entities.
