title: MVC Foolproof validation 'Sys is not defined'
body: <p>I used the package manager console to install these two packages: foolproof &amp; MvcExtentions.Foolproof. I included the foolproof script files in my bundle config (see below).</p>
  
  <p>Note that I didn't implement any foolproof code yet, I only installed the pacakges and included the script files and then ran the app.</p>
  
  <p>I'm getting the following clientside error:</p>
  
  <blockquote>
    <p>MvcFoolproofValidation.js: Uncaught ReferenceError: Sys is not defined </p>
  </blockquote>
  
  <pre><code>bundles.Add(new ScriptBundle("~/bundles/jquery").Include(
       "~/Scripts/jquery-{version}.js",
       "~/Scripts/jquery-ui-{version}.js",
       "~/Scripts/jquery.unobtrusive*",
       "~/Scripts/jquery.validate*",
       "~/Scripts/MvcFoolproofJQueryValidation.js",
       "~/Scripts/mvcfoolproof.unobtrusive.js",
       "~/Scripts/MvcFoolproofValidation.js"));
  </code></pre>
  
  <p>which renders as: (if its of any consequence)</p>
  
  <pre><code>&lt;script src="/Scripts/jquery-1.10.2.js"&gt;&lt;/script&gt;
  &lt;script src="/Scripts/jquery-ui-1.10.3.js"&gt;&lt;/script&gt;
  &lt;script src="/Scripts/jquery.unobtrusive-ajax.js"&gt;&lt;/script&gt;
  &lt;script src="/Scripts/jquery.validate.js"&gt;&lt;/script&gt;
  &lt;script src="/Scripts/jquery.validate.unobtrusive.js"&gt;&lt;/script&gt;
  &lt;script src="/Scripts/MvcFoolproofJQueryValidation.js"&gt;&lt;/script&gt;
  &lt;script src="/Scripts/mvcfoolproof.unobtrusive.js"&gt;&lt;/script&gt;
  &lt;script src="/Scripts/MvcFoolproofValidation.js"&gt;&lt;/script&gt;
