Add my project namespace to MVC web.config

Question

Can I not add my project namespace to the web.config so that the Razor view engine includes my project namespace for all pages in my project? Like so:

<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" />

        <add namespace = "MyProjectNamespace.NestedNamespace"/>
      </namespaces>
    </pages>
  </system.web.webPages.razor>

It isn't working.

This is an old question, but apparently there is still a bit of a problem with Visual Studio (2015 2017 2019 as of right now). After adding the namespaces to the web.config file in your Views folder, close and re-open all views. The namespaces were not recognized and the views would continuously throw runtime errors until I closed them all.
