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?
ASP.NET and Web Tools 2013.1 for Visual Studio 2012 has now been released and should resolved the MVC5 intellisense issue with VS 2012.
