Entry Point Not Found when adding external DLLs using RegisterVirtualPathFactory(engine)

Hi guys,

Just for context, I have a small web project with one Model and View. I want to add that to my main project by dropping the DLL in the bin folder.

In the main project, I'm adding assemblies using a PreApplicationStartMethod
foreach (assembly in assemblyList)
Then in Global.asax.cs, I try to insert the engines like so
var engine = new PrecompiledMvcEngine(assembly);
engine.UsePhysicalViewsIfNewer = true;

ViewEngines.Engines.Insert(0, engine);

// StartPage lookups are done by WebPages. 
I keep getting Entry Point Not Found when I load my website. DLLs don't have entry points, right?
[EntryPointNotFoundException: Entry point was not found.]
   System.Web.WebPages.IVirtualPathFactory.Exists(String virtualPath) +0
I searched for similar issues, some suggested checking the web.config of both projects. Nothing worked. Any help would be appreciated.

I'd guess there are some outdated WebPages assemblies, or something like that.

Yeah, that was it. Thanks Dave.

Now I only have one custom View Engine in the main project that does
protected override IView CreateView(ControllerContext controllerContext, string viewPath, string masterPath)
   if (the controller is a plugin)
      Type type = controllerType.Assembly.GetTypes().Where(t => typeof(WebPageRenderingBase).IsAssignableFrom(t) ...

      // some stuff

      return new PrecompiledMvcView( ...
Can I do the same for CreatePartialView?

I wonder how this would behave when paired with embedded resources.
