更新到AspNet Identity版本2后无法构建或迁移数据库

Question

从工作版本2 beta更新到AspNet.Identity(核心和EF)的RC后,我现在在尝试运行项目或迁移数据库时遇到错误.

这是我尝试添加迁移时在包管理器控制台中遇到的错误:

我现在无法运行我的项目,也不知道如何解决它.在我的解决方案中,我找不到任何对"Microsoft.AspNet.Identity.EntityFramework,Version = 1.0.0.0"的引用.

我通过在web.config文件中添加以下内容来修复此问题:

<dependentAssembly>
        <assemblyIdentity name="Microsoft.AspNet.Identity.EntityFramework" publicKeyToken="31bf3856ad364e35" culture="neutral" />
        <bindingRedirect oldVersion="0.0.0.0-2.0.0.0" newVersion="2.0.0.0" />
</dependentAssembly>
