title: Could not load file or assembly 'System.Web.WebPages.Razor, Version=3.0.0.0
body: <p>I want using external logins so I installed Oauth by package manager:</p>
  
  <pre><code> PM&gt; Install-Package Microsoft.AspNet.WebPages.OAuth
  </code></pre>
  
  <p>Then I got this error after installed it then I install razor:</p>
  
  <pre><code>PM&gt; Install-Package Microsoft.AspNet.Razor
  </code></pre>
  
  <p>But I still have this exception. Further more my application is an asp.net application and not a MVC application. Thanks for help.</p>
