I'm playing around with MVC 5 RC 1 in Visual Studio 2013 RC. Works very well.
Now I upgraded an existing MVC 4 project in VS 2012 to MVC 5 the same way as described here
I also changed the web.config(s) - see "upgrading from MVC4 to MVC5"
Everything (build, run web app, even intellisense) works perfectly except the syntax highlighting of Razor/C# code in views.
I also tried it with an MVC 5 project created in VS 2013. Same result. So I assume VS 2012 doesn't "understand" the new assemblies?!
Any known workaround or ideas to get highlighting back?
Microsoft released a new version of ASP.NET Web Tools for VS 2012. After installing syntax highlighting is back again.
Installing VS 2012 Update 4 was not enough.
A set of offline installers is available. The offline installers are easier to use than the Web Platform Tools invoker (WebNode11Pack.exe @ ~114KB):
