Question

When I install package Microsoft.Web.Helpers I get next warning txt file (after installing):
If the package is installed in an ASP.NET MVC 3 site, the site will not work.
If you’ve already installed the package into an MVC 3 application, uninstall it.
If the MVC 3 site does not work even after you have uninstalled the package, you might need to reinstall the ASP.NET MVC 3 packages as well.
I can use Microsoft.Web.Helpers in controller class but cant in the view (@using Microsoft.Web.Helpers not found).
I trying do next: Using ReCaptcha with MVC3 and razor? ReCaptcha and MVC3, problems getting Microsoft.Web.Helpers working .But it doesnt help.What I missed?

You’re missing the namespace in Views\Web.config (not the app root web.config).

<system.web.webPages.razor>
<host factoryType="System.Web.Mvc.MvcWebRazorHostFactory, System.Web.Mvc, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
<pages pageBaseType="System.Web.Mvc.WebViewPage">
  <namespaces>
    <add namespace="System.Web.Mvc" />
    <add namespace="System.Web.Mvc.Ajax" />
    <add namespace="System.Web.Mvc.Html" />
    <add namespace="System.Web.Optimization"/>
    <add namespace="System.Web.Routing" />
  </namespaces>
</pages>
