我已经实现了RoleProvider类中，有我创建的域类对象，它是在另一个程序集，我的组件具有引用的那一个。

I've implemented the RoleProvider class, there I created Domain class object which is in another assembly, my assembly has a reference to that one.

错误3类型System.Data.Entity.DbContext'是一个定义   未引用的程序集。您必须添加一个引用组件   的EntityFramework，版本= 6.0.0.0，文化=中立，   公钥= b77a5c561934e089。 D：的Visual Studio 2013 组   06 G06_Store Store.Facade StoreRoleProvider.cs 17 24 Store.Facade

Error 3 The type 'System.Data.Entity.DbContext' is defined in an assembly that is not referenced. You must add a reference to assembly 'EntityFramework, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'. D:Visual Studio 2013Group 06G06_StoreStore.FacadeStoreRoleProvider.cs 17 24 Store.Facade
