Razor intellisense not working in VS 2015

Question

When I load up my VS2013 projects in 2015, all my razor views are filled with red squiggly underlines.

@model, @Scripts @url, @Html.Partial, lambda expressions

Answer 1

Had the same issue. ResetUserData didn't work, etc. What ResetUserData did do though was reset some of the dialogs that were suppressed. Ultimately a dialog popped up stating "The 'CompatiblityCheckerPackage' did not load correctly." It told me to go to my users folder (path below) and check out the ActivityLog.xml. Turns out WebEssentials 2015 did not install correctly and was failing to load. I installed WebEssentials again and the Intellisense errors went away.

Full Path for me:

C:\Users\xxx\AppData\Roaming\Microsoft\VisualStudio\14.0\ActivityLog.xml

Hope this helps.
