title: Could not load file or assembly 'WebMatrix.WebData' Error
body: <p>I am getting an exception message on the server hosting my ASP.NET MVC4 application. The application runs fine but when you make certain request that use types contained in certain third-party assemblies, I get the "<strong>Could not load file or assembly...</strong>" error message. 
  The most nagging of which is the </p>
  
  <blockquote>
    <p>Could not load file or assembly 'WebMatrix.WebData' or one of its dependencies. The system cannot find the file specified.</p>
  </blockquote>
  
  <p>which prevents emails sent from my app from displaying the containing images (the images are sourced from a folder outside the document root projected via a virtual directory).  </p>
  
  <p>Under references, I have made sure that the <strong>Copy To Local</strong> property of the assembly is set to true. I am almost at my wits end.</p>
  
  <p><strong>UPDATE</strong>
  I have noticed third party assemblies that are shipped in the bin folder all report the same error even though they exist there.</p>
  
  <p>Thanks</p>
