after upgrade, all the pages see Models as Object.

I’ve upgraded using migration guide here

basically just copying some scripts, and re-mapping mvc assembly reference to 3.0

For some reason, all of my controls are now not seeing any properties on my models.

here is how i define the model type:

<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<WebMVC.Models.WeatherModel>" %>

usage:

<%: Html.TextBox("DateFromText", Model.DateFrom.ToShortDateString())%>

i now get compile errors that “object” does not contain definition for AnyProperty.

UPDATE

thanks to SLax i fixed the object issue. Now getting the following error:

The type ‘System.Data.Objects.DataClasses.ComplexObject’ is defined in an assembly that is not referenced. You must add a reference to assembly ‘System.Data.Entity, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089’.

ok.. fixed this by adding assembly reference in web.config:

<add assembly="System.Data.Entity, Version=4.0.0.0, Culture=neutral, PublicKeyToken=B77A5C561934E089"/>

    You probably have references to System.Web.Mvc.dll version 2 in one of the two Web.config files.
