c# - Entity Framework 架构验证失败

Question

我正在尝试为 ASP.NET MVC5 项目运行一个项目模板，该项目也使用 Owin 进行身份验证。项目构建成功，但当我尝试创建用户或执行登录或尝试启用迁移时，出现以下与 XML 模式验证相关的错误。我试图找到抛出错误的模型但找不到模型(看起来像 Owin 自动生成的模型)。目标.NET框架为4.5.1， Entity Framework 库版本为6.0.0。

感谢您在此问题上的帮助。

我遇到了同样的问题，我在几分钟前偶然找到了解决方案。这是解决方案的名称。当我拥有 MVC5Example1.0 时，它给了我错误，但是当我将它更改为 MVC5Example1 时，它起作用了。希望它也能帮到您。
