在 asp.net mvc 中使用注册/登录操作

Question

我在启动新的 ASP.NET 应用程序时遇到问题。我选择带有个人用户帐户身份验证的 asp.net mvc 模板，项目正常生成并启动。我的问题是：我需要做什么才能使用注册/登录选项？据我了解，负责这些操作的方法是自动生成的，但是我应该对有关用户信息的数据库模式做一些事情（它不应该也自动创建吗？）。

无论如何，在注册表单中填写字段后，我收到错误，无法找到文件，并且在第 155 行找到错误： var result = wait UserManager.CreateAsync(user, model.Password);

我正在 Windows 8 上使用 Visual Studio Community 2015。提前谢谢您
