列名称'Discriminator'无效

时间：2015-04-21 16:28:51

标签： asp.net-mvc

我有一个使用ASP NET MVC 5数据库来验证用户的现有AppUsers。它已经工作了一年多。

今天，我创建了一个新的演示ASP MVC 5应用程序，并将[Authorize]标记设置为特定的[AspNetRoles]角色。我还在新应用程序connectionString文件中设置了“AppUsers”web.config。它与第一个现有应用程序的连接相同

当我尝试使用新应用程序登录时，我收到如下所示的错误。我假设我可以使用“AppUsers”DB来验证使用不同应用程序的用户。任何关于如何解决这个问题的建议将不胜感激。我搜索了网络，但这个错误似乎有很多不同的原因，我所看到的似乎都没有解释我的问题。

谢谢 麦克

答案 0 :(得分：0)

解决方案是对所有nuget包进行全面更新。在我的例子中，我创建了新项目，从nuget更新了EF，实现了连接字符串更改以使用“AppUsers”DB来设置授权以对用户进行身份验证。

这让我陷入了主题错误。

Alundra建议迁移。但是，我过去已经完成了迁移。下一个合乎逻辑的步骤是更新nuget包。这解决了这个问题。我怀疑罪魁祸首只是在开始时才更新EF。
