在尝试将DI与Identity 2.0一起使用时，我遇到了Unity问题。我的项目是MVC5 Wep Api2 REST服务和AngularJS。
这是我迄今为止所尝试的内容:(请注意：MyExtendedGroup : IdentityRole)
.RegisterType<MySecurityContext>("MySecurityCtx", new PerResolveLifetimeManager())
.RegisterType<IRoleStore<MyExtendedGroup, string>, RoleStore<MyExtendedGroup, string, IdentityUserRole>>("MyRolesStore", new InjectionConstructor(new ResolvedParameter<MySecurityContext>("MySecurityCtx")))
.RegisterType<IGroupAsyncService, GroupAsyncService>("groupAsyncService", new InjectionConstructor(new ResolvedParameter<IRoleStore<MyExtendedGroup>>("MyRoleStore")))
.RegisterType<GroupsAsyncController>(new InjectionConstructor(new ResolvedParameter<IGroupAsyncService>("groupAsyncService")))
我被要求发布控制器的构造函数。这是：
public GroupsAsyncController(IGroupAsyncService service)
{
_service = service;
}
这是完整的堆栈跟踪：

我被困的地方。在此先感谢您的帮助！
更新：基本上我不知道如何使用Unity DI： new UserManager（new UserStore（new MySecurityContext（）））; 要么 new RoleManager（new RoleStore（new MySecurityContext（）））;
