修复此问题并支持EF6 RC的ASP.NET标识刷新将很快提供
更新：新版本是。名称空间和移动类型有一些变化。我更新了Beta1-RC1中的示例
您可以查看以下命令以获得所需更改的列表。我将很快在项目上添加一些文档我在将EntityFramework dll版本6添加到MVC4项目时遇到此错误。将EntityFramework dll降级到版本5解决了我的问题！刚刚更新了新包，现在发现了许多错误。IdentityStoreManager cou找不到ld，找不到IdentityStoreContext等。是否重命名或移动了某些名称空间？版本之间发生了很大变化-此处有更多信息-hi@pranav rastogi，感谢更新的代码。我在上一个项目中遇到了问题，试图使其与我现有的结构一起工作。希望提供一些文档d、 顺便说一句，当我替换项目中的代码时，它会创建以AspNet为前缀的表，而示例项目中没有
