MVC, Views and System.Data.Entity
asp.net-mvc, c#, entity-framework
Solution
You should make sure the web.config looks as following:
<compilation debug="true" targetFramework="4.0">
<assemblies>
<add assembly="System.Data.Entity, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" />
</assemblies>
</compilation>

Problem
I have a Repository Project that is added to my MVC application. Within my C# code, of the MVC Web App, I have had to add a reference to System.Data.Entity so that I can access the objects from my Repository. So the following fails if I do not have the reference added; ``` DataRepository<Store> repo = new DataRepository<Store>(); List<Store> allSorted = repo.All(x => x.name); ``` Now I want to pass that list to my Partial View, which sits within a FVM and it's the FVM that I pass to the Partial View. So the index.aspx code; ``` <%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<StoresFVM>" %> <% Html.RenderPartial("StoreList", Model.StoreListFVM); %> ``` And the ASCX code; ``` <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<StoreListFVM>" %> <% SelectList storeList = new SelectList(Model.Stores.Select(x => new { Value = x.number, Text = x.name }),"Value","Text"); %> <%= Html.DropDownList("SelectedStore", storeList) %> ``` However, I get an error informing me that I need to include a reference to System.Data.Entity in the ascx. I don't get why for one. I have tried adding the namespace to the web.config file and I have tried importing the namespace at the top of the ascx page. Thoughts? EDIT \nasfile02\Visual Studio 2010\Projects\TOM\TOM\Views\Stores\PartialViews\StoreList.ascx(4): error CS0012: The type 'System.Data.Objects.DataClasses.EntityObject' 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'. EDIT ``` namespace TOM.FormViewModels { public class StoresFVM { public StoreListFVM StoreListFVM { get; set; } } } namespace TOM.FormViewModels { public class StoreListFVM { public List<Store> Stores { get; set; } } } ```
