title: Object reference not set to an instance of an object error on Visual Studio 2013
body: <p>I am getting this error pop up box in Visual Studio 2013 Pro version. I get it if i paste something onto a .cshtml page while running the project. Currently I am getting it on an MVC 5 project. I am just wondering it is a bug to Visual Studio 2013 or I just messed up my Visual Studio. My VS is genuine version. I also have 2010, 2012 and 2013 Express installed on my machine. </p>
  
  <p>UPDATE:</p>
  
  <p>I found out it happens when I have Razor syntax in the CSS block.</p>
