title: VS2015 ASP.NET MVC the name 'model' does not exist in the current context
body: <p>I was working on an ASP.NET MVC 4 in VS2013 and everything was fine, then I've uninstalled 2013 and installed 2015, I was able to open the project, build it and even run, everything works fine (run/debug). The problem is that all my views are covered in errors:  </p>
  
  <pre><code>the name 'model\Scripts\Url...' does not exist in the current context  
  </code></pre>
  
  <p>In addition, the .Where method of a list in the model shows an error as well as all the @Html helpers. I want to emphasize that the project still works w\o any problems so the issue is UI or package related. I tried to force uninstall\upgrade Microsoft.AspNet.MVC but the package manager console throws an error and rolls back the attempt. I can provide any necessary info if it helps, thank you in advance.</p>
