[Solved] CS1061: 'System.Web.Mvc.HtmlHelper<dynamic>' does not contain a definition for 'Telerik'

[javier]

Hello,

I have a simple MVC site, with this code in the _Layout.cshtml:
    @using Telerik.Web.UI
    @(Html.Telerik().StyleSheetRegistrar().DefaultGroup(group => group
                        .Add("telerik.examples.css")
                        .Add("telerik.common.css")
                        .Add("telerik." + Html.GetCurrentTheme() + ".css")
                        .Add("telerik.rtl.css")
                        .Combined(true)
                        .Compress(true))
                        )
And this is a View where I need to use the calendar control:
 <div class="clearfix grpelem" id="u392-4"><!-- content -->
        @(Html.Telerik().DatePicker()
                        .Name("minDate")
                        .Value((DateTime)ViewData["minDate"])
                        )
</div>

I have already read tons of posts with similar an issues and after many updates to my files my global  config looks like:
   <configSections>
    <sectionGroup name="telerik">
      <section name="webAssets" type="Telerik.Web.Configuration.WebAssetConfigurationSection, Telerik.Web" requirePermission="false"/>
    </sectionGroup>
  </configSections>

    <pages>
      <namespaces>
        <add namespace="System.Web.Helpers" />
        <add namespace="System.Web.Mvc" />
        <add namespace="System.Web.Mvc.Ajax" />
        <add namespace="System.Web.Mvc.Html" />
        <add namespace="System.Web.Routing" />
        <add namespace="System.Web.WebPages"/>
        <add namespace="Telerik.Web.UI" />
 
      </namespaces>
    </pages>

And the pages config looks like:
  <system.web.webPages.razor>
    <host factoryType="System.Web.Mvc.MvcWebRazorHostFactory, System.Web.Mvc, Version=3.0.0.0, 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.Routing" />
        <add namespace="Telerik.Web" />
        <add namespace="Telerik.Web.UI" />
      </namespaces>
    </pages>
  </system.web.webPages.razor>

This is the error:

Line 17: @using Telerik.Web.UI Line 18: @(Html.Telerik().StyleSheetRegistrar().DefaultGroup(group => group Line 19: .Add("telerik.examples.css") Line 20: .Add("telerik.common.css")

After spending many hours reading many telerik posts I concluded that all questions are related to older controls versions than mine. My version is: Telerik_Extensions_for_ASPNET_MVC_2012_1_419_Commercial.msi, so namespaces changed ("Telerik.Web.Mvc.UI" does not exist) and I edited my updates according to that.

Thank you,
