ASP.Net 5 + 身份 3 覆盖默认角色实现

ASP.Net 5 + Identity 3 Overriding default Roles implementation

我必须扩展 Identity 3 中 Roles 的默认实现。所以我写了子类:

public class ApplicationRole:IdentityRole
{
    public string Description { get; set; }
    public DateTime CreationDate { get; set; }
}
public class ApplicationUserRole:IdentityUserRole<string>
{
    public DateTime StartDate { get; set; }
    public DateTime EndDate { get; set; }
}

然后,因为我希望 Entity Framework 7 将我的数据存储在相同的默认表中,所以我在 ApplicationDbContextOnModelCreating 方法中编写了以下内容:

builder.Model.RemoveEntityType(new Microsoft.Data.Entity.Metadata.EntityType(typeof(IdentityRole), builder.Model));
builder.Model.RemoveEntityType(new Microsoft.Data.Entity.Metadata.EntityType(typeof(IdentityUserRole<string>),builder.Model));

builder.Entity<ApplicationRole>().ToTable("AspNetRoles");              
builder.Entity<ApplicationUserRole>().HasKey(r => new { UserId = r.UserId, RoleId = r.RoleId });
builder.Entity<ApplicationUserRole>().ToTable("AspNetUserRoles");

我也在ApplicationDbContext中定义了属性:

public DbSet<ApplicationUserRole> MyUserRoles { get; set; }
public DbSet<ApplicationRole> MyRoles { get; set; }

(我试图用 new 覆盖默认 UserRolesRoles,但 EF 迁移抛出 AmbiguousMatchException) 现在我想我必须在应用程序配置中注册我的自定义实现,但我不知道如何。我写在 Startup.cs:

services.AddIdentity<ApplicationUser, ApplicationRole>(/*options*/)

并更改了 ApplicationDbContext 的超类:

public class ApplicationDbContext : IdentityDbContext<ApplicationUser,ApplicationRole,string>

我还应该做什么?或者也许我必须以完全不同的方式解决任务?

正在查看 IdentityDbContext and it seems you cannot use your own IdentityUserRole class in Identity v3. In fact, there is an open issue 的源代码以将其添加回去。
