C# 当前类型，IUserStore<；应用程序用户>；和DbConnection分别是接口和抽象类，无法构造

如果我浏览到

http://localhost:58472/Account/Register

我有这个例外

系统。无效操作异常：

当前类型，

IUserStore:

将其添加到
帐户控制器中
：

// two fields added
private readonly UserManager<ApplicationUser> _userManager;
private readonly RoleManager<IdentityRole> _roleManager;

// constructor added
public AccountController(
    IUserStore<ApplicationUser> userStore, 
    IRoleStore<IdentityRole> roleStore, 
    ApplicationSignInManager signInManager)
{
    _userManager = new UserManager<ApplicationUser>(userStore);
    _roleManager = new RoleManager<IdentityRole>(roleStore);
    SignInManager = signInManager; // I need this
}

public ApplicationSignInManager SignInManager // I need this
{
    get
    {
        return _signInManager ?? 
            HttpContext.GetOwinContext().Get<ApplicationSignInManager>();
    }
    private set
    {
        _signInManager = value;
    }
}

public UserManager<ApplicationUser> UserManager // replace by other property 
                                                // type of ApplicationUserManager 
{
    get
    {
        return _userManager ?? 
            HttpContext.GetOwinContext().GetUserManager<ApplicationUserManager>();
    }
    //private set // comment this because _usermanager is readonly.
    //{
    //    _userManager = value;
    //}
}

//public ApplicationUserManager UserManager // replaced by the property type of 
//                                          // UserManager<ApplicationUser>
//{
//    get
//    {
//        return _userManager ?? 
//            HttpContext.GetOwinContext().GetUserManager<ApplicationUserManager>();
//    }
//    private set
//    {
//        _userManager = value;
//    }
//}

没有从
RoleStore
到
IRoleStore
的隐式引用转换

我终于找到了解决问题的办法。我已将此代码添加到Unity manager中

container.RegisterType<IUserStore<ApplicationUser>, UserStore<ApplicationUser>>();

container.RegisterType<DbContext, ApplicationDbContext>(new HierarchicalLifetimeManager());
container.RegisterType<UserManager<ApplicationUser>>(new HierarchicalLifetimeManager());
container.RegisterType<IUserStore<ApplicationUser>, UserStore<ApplicationUser>>(new HierarchicalLifetimeManager());
container.RegisterType<AccountController>(new InjectionConstructor());

container.RegisterType（新的层次结构CallifetimeManager（））；
RegisterType（新的层次结构CallifetimeManager（））；
RegisterType（新的层次结构CallifetimeManager（））；
RegisterType（新的InjectionConstructor（））；
更新H.Pauwelyn的答案。最初的问题是Unity试图用两个参数调用构造函数

public AccountController(
    ApplicationUserManager userManager,
    ApplicationSignInManager signInManager)
{
    UserManager = userManager;
    SignInManager = signInManager;
}

下一行将告诉Unity调用无参数构造函数，而不需要其他任何东西。这对我有用

container.RegisterType<AccountController>(new InjectionConstructor());

container.RegisterType（新注入构造函数（））；
您是否缺少IUserStore的寄存器类型？也许会有帮助。@Jay:谢谢你的提示，但我现在有一个例外。我的问题中有更多信息。看问题。我只是在安装Unity后才开始得到OP所得到的错误。似乎与Unity的依赖解析程序不使用本机标识功能有关。注册这些类型修复了它。
