  I have upgraded my MVC 3 project to MVC 5 and when I run the application I receive ClientDependencyModule.cs` file not found runtime exception.</p>
  
  <p><strong>How can I solve this problem ??</strong> </p>
  
  <p><em>Error Description :</em></p>
  
  <p>An exception of type '<code>System.TypeAccessException</code>' occurred in <code>ClientDependency.Core.Mvc.dll</code> but was not handled in user code
  Additional information: Attempt by security transparent method '<code>ClientDependency.Core.Mvc.MvcFilter.ValidateCurrentHandler()</code>' to access security critical type '<code>System.Web.Mvc.MvcHandler</code>' failed.
  Assembly '<code>ClientDependency.Core.Mvc, Version=1.7.0.4, Culture=neutral, PublicKeyToken=null</code>' is marked with the <code>AllowPartiallyTrustedCallersAttribute</code>, and uses the level 2 security transparency model. 
   Level 2 transparency causes all methods in <code>AllowPartiallyTrustedCallers assemblies</code> to become security transparent by default, which may be the cause of this exception.</p>
  
  <p>Please  let me know if I can provide any more info regarding. Any help is greatly appreciated !!!  Thank You :)</p>
