'System.Web.Mvc.HtmlHelper' does not contain a definition for 'RenderPartial' - ASP.Net MVC

Question

I've been trying to run ASP.Net MVC 1.0 on one machine, but can't get past this. I create a new MVC project (C#). It creates all the folders, views, controllers, models etc. All good. Then, when I hit F5, I get the following:

d:\VSCode2008\MVC\MvcApplication1\Views\Shared\Site.Master(19): error CS0117: 'System.Web.Mvc.HtmlHelper' does not contain a definition for 'RenderPartial'

this happens at the following line:

httpHandler.ProcessRequest(HttpContext.Current); in Default.aspx.cs

It seems when it is trying to do a RenderPartial() to render the logon partial.

I have version 3.51 of .Net framework installed. I installed version 1.0 of MVC, and the assembly clearly has RenderPartial() as extension methods of HtmlHelper.

Anyone seen anything similar? I have found some posts about similar problems with betas and RCs but the suggested fixes have not woredk.

I am loving the theory of MVC but it is not letting me play!

Answer 1

Since you are referencing it in your Code Behind (ie. Default.aspx.cs) you need to include the namespace at the top of the file.

using System.Web.Mvc.Html;

is the Namespace that includes the RenderPartial extension method.

Answer 2

Just trying to rule out the obvious here, but can you make sure have this in the namespaces section of the web.config?

<add namespace="System.Web.Mvc.Html"/>
