MVC 4 @Scripts “does not exist”

Question

I have just created an ASP.NET MVC 4 project and used Visual Studio 2012 RC to create a Controller and Razor Views for Index and Create Actions.

Answer 1

When I enter on a page that haves this code:

@section Scripts {
    @Scripts.Render("~/bundles/jqueryval")
}

This error occurs: Error. An error occurred while processing your request.

And this exception are recorded on my logs:

System.Web.HttpException (0x80004005): The controller for path '/bundles/jqueryval' was not found or does not implement IController.
   em System.Web.Mvc.DefaultControllerFactory.GetControllerInstance(RequestContext requestContext, Type controllerType)
...

I have tried all tips on this page and none of them solved for me. So I have looked on my Packages folder and noticed that I have two versions for System.Web.Optmization.dll:

• Microsoft.AspNet.Web.Optimization.1.1.0 (v1.1.30515.0 - 68,7KB)
• Microsoft.Web.Optimization.1.0.0-beta (v1.0.0.0 - 304KB)

My project was referencing to the older beta version. I only changed the reference to the newer version (69KB) and eveything worked fine.

I think it might help someone.
