title: MvcSiteMapProvider MVC 5 custom ViewBase?
body: <p>I have a problem after upgrading MvcSiteMapProvider MVC 4 to MVC 5.
  I use a custom "pageBaseType" for my views, and it seems that MvcSiteMapProvider MVC 5 does
  not allow that?
  I keep getting the error:</p>
  
  <pre><code>The view at '~/Views/Shared/DisplayTemplates/SiteMapPathHelperModel.cshtml' must derive from WebViewPage, or WebViewPage&lt;TModel&gt;.
  </code></pre>
  
  <p>at   @Html.MvcSiteMap().SiteMapPath().</p>
  
  <p>However, my custom viewbase does inherit System.Web.Mvc.WebViewPage.
  Am I missing something here?</p>
  
  <p>If I remove the line @Html.MvcSiteMap().SiteMapPath() the page works fine, but without the sitemappath, of course.</p>
  
  <p>Thanks in advance for any help!</p>
