I don't know, all of sudden Razor syntax showing in Red. I suspended and resumed and also closed VS and restarted still the same. Anything else to do?

Check the references in the /Web.config and the Views/Web.config. If they are correct, try a clean and rebuild. If that still does not work, you can manually delete the bin folder and VS will recreate it anew.
