无法基于DBContext创建强类型Razor视图 [英] Can't create strongly typed Razor View based on DBContext

问题描述

我可以根据强类型集合创建视图。

@inherits System.Web.Mvc.WebViewPage< IEnumerable< Data.ProductCategory>>

这很好用，

I can create a view based on a strongly typed collection.
@inherits System.Web.Mvc.WebViewPage<IEnumerable<Data.ProductCategory>>
This works fine,

当我根据基于DBContext的类创建一个剃刀视图时，
@inherits System.Web.Mvc。 WebViewPage< Data.MNG_Model>

应用程序抛出和错误：

CS0012：类型'System.Data.Entity.DbContext'在未引用的程序集中定义。

你必须添加一个对程序集'Microsoft.Data.Entity.Ctp，

When I create a razor view with based on the class that is based on the DBContext
@inherits System.Web.Mvc.WebViewPage<Data.MNG_Model>
The App throws and error:
CS0012: The type 'System.Data.Entity.DbContext' is defined in an assembly that is not referenced.
You must add a reference to assembly 'Microsoft.Data.Entity.Ctp,

的引用嗯我显然有对CTP dll的引用，因为所有这些优秀代码的第一个东西都可以工作

，直到我尝试创建基于DBContext的强类型视图。

Well I obviously have references to the CTP dll because all this great code first stuff works
until I try and create the strongly typed view based on DBContext.

这是我的模型。

  public class MNG_Model : DbContext
  {
    public DbSet<ProductCategory> ProductCategories { get; set; }
    public DbSet<PriceCategory> PriceCategories { get; set; }
  }
  public class ProductCategory
  {
    public int ID { get; set; }
    public string Description { get; set; }
    public virtual ICollection<Product> Products { get; set; }
  }
  public class PriceCategory
  {
    public int ID { get; set; }
    public string Description { get; set; }
    public virtual ICollection<Product> Products { get; set; }
  }

推荐答案

您需要在web.config文件中添加一个条目，让MVC知道在编译页面时引用CTP4程序集：

You need to add an entry to your web.config file to let MVC know to reference the CTP4 assembly when it compiles pages:

 <system.web>
  <compilation debug="true" targetFramework="4.0">
   <assemblies>
    <add assembly="System.Web.Abstractions, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
    <add assembly="System.Web.Routing, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
    <add assembly="System.Web.Mvc, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
    <add assembly="Microsoft.Data.Entity.CTP, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" />
   </assemblies>
  </compilation>
