无法将 Class 转换为泛型接口

Question

我正在尝试通过分组声明来扩展 AspNet Identity。我正在使用新的 QueryAppGroup 实体执行此操作。我希望能够添加和删除任何特定组的声明。添加没问题，但我找不到删除特定声明的方法（例如，通过 Id）所以这是我的计划：

创建一个名为 QueryAppGroupClaim 的中间实体，以便 IdentityUserClaim 与其具有一对零或一的关系。
通过删除任何特定的 QueryAppGroupClaim 实体，删除应该级联到 IdentityUserClaim。
为此，我需要通过导航属性将 IdentityUserClaim 扩展回 QueryAppGroupClaim（请参阅 ApplicationUserClaim）

代码：

public class ApplicationUserClaim : IdentityUserClaim<string>
{
    [ForeignKey("QueryAppGroupClaim")]
    public virtual int QueryAppGroupClaimId { get; set; }
    public virtual QueryAppGroupClaim QueryAppGroupClaim { get; set; }
}

public class QueryAppGroup
{
    public QueryAppGroup()
    {
    }

    [DatabaseGenerated(DatabaseGeneratedOption.Identity)]
    public int Id { get; set; }

    [ForeignKey("ApplicationUser")]
    public String UserId { get; set; }

    public String Desc { get; set; }

    public String ImpersonateClaimType { get; set; }

    public virtual ApplicationUser ApplicationUser { get; set; }
}

public class QueryAppGroupClaim
{
    public QueryAppGroupClaim()
    { }

    [Key, ForeignKey("IdentityUserClaim")]
    public int ClaimId { get; set; }
    public virtual ApplicationUserClaim IdentityUserClaim { get; set; }

    [ForeignKey("QueryAppGroup")]
    public int QueryAppGroupId { get; set; }
    public virtual QueryAppGroup QueryAppGroup { get; set; }
}


public class ApplicationUser : IdentityUser<string, IdentityUserLogin, IdentityUserRole, ApplicationUserClaim>, IUser, IUser<string>
{
    //...
}

public class ApplicationDbContext : IdentityDbContext<ApplicationUser, IdentityRole, string, IdentityUserLogin, IdentityUserRole, ApplicationUserClaim>
{
    //...
    public DbSet<QueryAppGroup> QueryAppGroups { get; set; }

    public DbSet<QueryAppGroupClaim> QueryAppGroupClaims { get; set; }

    protected override void OnModelCreating(DbModelBuilder modelBuilder)
    {
        base.OnModelCreating(modelBuilder);
        modelBuilder.Entity<ApplicationUserClaim>()
            .HasOptional(t => t.QueryAppGroupClaim)
            .WithRequired(t => t.IdentityUserClaim)
            .WillCascadeOnDelete();
    }
}

public class ApplicationUserStore : UserStore<ApplicationUser,IdentityRole,string, IdentityUserLogin, IdentityUserRole, ApplicationUserClaim>
{
    //...
    //Already exists with an override of RemoveClaimAsync(...)
}

public class ApplicationUserManager : UserManager<ApplicationUser>
{
    public ApplicationUserManager(IUserStore<ApplicationUser> store)
        : base(store)
    {
    }

    public ApplicationUserManager(ApplicationUserStore store)
        : base(store)
    {

    }
    //...
}

我在调用基础构造函数 Argument 1: cannot convert from 'ApplicationUserStore' to 'Microsoft.AspNet.Identity.IUserStore<ApplicationUser>' 时收到 public ApplicationUserManager(ApplicationUserStore store) : base(store) 的编译错误。我的 class ApplicationUserStore 扩展了 UserStore，它本身实现了许多接口，一个是 IUserStore。我看不出如何解决这个问题。请帮忙。

我们也欢迎任何让主要 objective 更简单的建议！

尝试显式实现 IUserStore<ApplicationUser> 以及 UserStore 的基本 class 声明，如下所示：

public class ApplicationUserStore :
    UserStore<ApplicationUser, IdentityRole, string, IdentityUserLogin, IdentityUserRole, ApplicationUserClaim>,
    IUserStore<ApplicationUser>
{
    public ApplicationUserStore(DbContext context) : base(context)
    {

    }
}
