Question

我目前正在尝试向我的应用添加角色，而且我收到此错误＆＃34;实体类型IdentityRole不是当前上下文的一部分＆＃34;。我以前有同样的错误，除了AppRole，但我通过在AppIdentityDbContext类中包含IdentityDbContext之后的所有参数解决了这个问题，但我无法解决这个问题，谢谢你的帮助

这是我在

上收到错误的行

ClaimsIdentity ident = await UserManager.CreateIdentityAsync(user,DefaultAuthenticationTypes.ApplicationCookie);

DbContext类

 public class AppIdentityDbContext : IdentityDbContext<User, AppRole, string, IdentityUserLogin, IdentityUserRole, IdentityUserClaim>
    {
        public AppIdentityDbContext() : base("ProGP_Db") { }

        static AppIdentityDbContext()
        {
            Database.SetInitializer<AppIdentityDbContext>(new IdentityDbInit());

            return new AppIdentityDbContext();
        }

            // initial configuration will go here

AppUserManager Class

public class AppUserManager : UserManager<User,string>
{

    public AppUserManager(IUserStore<User> store): base(store){}


    public static AppUserManager Create(IdentityFactoryOptions<AppUserManager> options,IOwinContext context)
    {
        AppIdentityDbContext db = context.Get<AppIdentityDbContext>();
        AppUserManager manager = new AppUserManager(new UserStore<User>(db));

        manager.PasswordValidator = new PasswordValidator
        {
            RequiredLength = 6,
            RequireNonLetterOrDigit = false,
            RequireDigit = false,
            RequireLowercase = true,
            RequireUppercase = true
        };


        return manager;
    }
}

AppRoleManager

public class AppRoleManager : RoleManager<AppRole>,IDisposable
{
    public AppRoleManager(RoleStore<AppRole> store):base(store)
    { }


    public static AppRoleManager Create(IdentityFactoryOptions<AppRoleManager> options, IOwinContext context)
    {
        //AppIdentityDbContext db = context.Get<AppIdentityDbContext>();
        //AppRoleManager manager = new AppRoleManager(new RoleStore<AppRole>(db));
        return new AppRoleManager(new RoleStore<AppRole>(context.Get<AppIdentityDbContext>()));

        //return manager;
    }
}

AppRole类

  public class AppRole:IdentityRole
{
    public AppRole():base() { }


    public AppRole(string name) : base (name)
    {
    }
}

问题在于我已经明确声明了IdentityRole的UserStore，我创建了另一个从UserStore扩展的类，解决了这个问题。

public class AppUserStore<TUser> : UserStore<TUser, Role, string, IdentityUserLogin, IdentityUserRole, IdentityUserClaim>, IUserStore<TUser>, IUserStore<TUser, string>, IDisposable where TUser : Microsoft.AspNet.Identity.EntityFramework.IdentityUser {

public AppUserStore(DbContext context) :base(context) {}     }

实体类型IdentityRole不是当前上下文的一部分
