I have MVC4 project which I created with VS2010 and ReSharper 6. All Razor files were successfully parsed/recognized by ReSharper and I had full intellisense inside them, i.e. properties of the "Model" object, navigation to actions in controllers, etc.
However after updating to VS2012 with ReSharper 7.1 all Razor bits are highlighted in red and if I hover them I get "Cannot resolve symbol 'Model'" (or 'Html' for @Html, etc).
What would cause this?
