Razor syntax highlighting not working in VS 2012 with MVC 5

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):

If you want an offline installer then please goto http://www.microsoft.com/en-us/download/details.aspx?id=41532

  • AspNetWebTools2013_1Setup.exe @ ~39MB
  • WebToolsExtensionsVS.msi (for Visual Studio 2012 standard edition[s]) @ ~21MB
  • WebToolsExtensionsVWD.msi (for Visual Studio 2012 free "Web" edition[s]) @ ~21MB

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.

This release brings a ton of great improvements, and include some fantastic enhancements to ASP.NET MVC 5, Web API 2, Scaffolding and Entity Framework to users of Visual Studio 2012 and Visual Studio 2012 Express for Web.

This answer claims that VS2012 can't understand Razor 3, so you (and me) will have to upgrade to VS2013
