I'm just in the process of upgrading my Preview 5 application to Beta 1, and I'm nearly there save for this one error when trying to render a control:
'System.Web.Mvc.HtmlHelper' does not contain a definition for 'RenderPartial' and no extension method 'RenderPartial' accepting a first argument of type 'System.Web.Mvc.HtmlHelper' could be found (are you missing a using directive or an assembly reference?)
My markup (in the .aspx View Content Page) is:
<% Html.RenderPartial("Controls/UserForm", ViewData); %>
I've tried using Microsoft.Web.Mvc but to no avail. Does anyone know where Html.RenderPartial has gone, or what alternative I could use?
And also don't forget to add namespaces like below to the web config, I think preview 5 default web.config does not have System.Web.Mvc.Html in it:
<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="System.Linq"/>
<add namespace="System.Collections.Generic"/>
</namespaces>
