我决定使用.NET Core 2,我遇到了问题.Microsoft文档说基类中不再存在导航属性IdentityUser,我希望它们能够恢复.

我可以参考每个用户在我的视图模型中的角色,但是当我将它放入我的应用程序用户类时:

public virtual ICollection<IdentityUserRole<int>> Roles { get; } = 
  new List<IdentityUserRole<int>>();
public virtual ICollection<IdentityUserClaim<int>> Claims { get; } = 
  new List<IdentityUserClaim<int>>();
public virtual ICollection<IdentityUserLogin<int>> Logins { get; } = 
  new List<IdentityUserLogin<int>>();

并将其添加到我的模型构建器:

 builder.Entity<ApplicationUser>()
    .HasMany(e => e.Claims)
    .WithOne()
    .HasForeignKey(e => e.UserId)
    .IsRequired()
    .OnDelete(DeleteBehavior.Cascade);

builder.Entity<ApplicationUser>()
    .HasMany(e => e.Logins)
    .WithOne()
    .HasForeignKey(e => e.UserId)
    .IsRequired()
    .OnDelete(DeleteBehavior.Cascade);

builder.Entity<ApplicationUser>()
    .HasMany(e => e.Roles)
    .WithOne()
    .HasForeignKey(e => e.UserId)
    .IsRequired()
    .OnDelete(DeleteBehavior.Cascade);

我收到了错误 The entity type 'IdentityUserLogin<int>' requires a primary key to be defined.
