如何设置我的应用程序，以便身份和域对象在同一个上下文中？

Question

我正在使用和MVC 5项目，我尝试设置我的应用程序的上下文，以便它使用身份上下文和应用程序域上下文作为一个上下文。我对依赖注入更新一点，我想我可能在某个地方犯了一个错误，导致这些错误无法正常工作。我已经看到很多答案，说明你只需要创建两个连接字符串，一个是实体框架连接字符串，另一个是sql连接字符串。然后将sql连接字符串传递给您的上下文，不知何故，MVC将知道使用哪一个。我认为这可能与我在每个请求应用程序数据库上下文中使用containercoped容器这一事实有关，但在删除容器范围约束时它仍然失败。

当我使用sql连接字符串时，我得到一个错误，说applicationUser不是当前上下文的一部分，但域对象似乎查询正常。当我使用我的实体框架连接字符串时，context.Users对象为空，表示标识内容不起作用。我哪里错了？如果您需要其他代码信息，请告诉我，我会发布。
