Question

我有两个独立数据库的ASP.NET MVC应用程序。第一个数据库是标准的身份上下文

  public class ApplicationUser : IdentityUser  {
    public ClaimsIdentity GenerateUserIdentity(ApplicationUserManager manager) {
        // Note the authenticationType must match the one defined in CookieAuthenticationOptions.AuthenticationType
        var userIdentity = manager.CreateIdentity(this, DefaultAuthenticationTypes.ApplicationCookie);
        // Add custom user claims here
        return userIdentity;
    }

    public Task<ClaimsIdentity> GenerateUserIdentityAsync(ApplicationUserManager manager)  {
        return Task.FromResult(GenerateUserIdentity(manager));
    }
}

public class ApplicationDbContext : IdentityDbContext<ApplicationUser> {
    public ApplicationDbContext()
        : base("ApplicationConnection", throwIfV1Schema: false) { }

    public static ApplicationDbContext Create() {
        return new ApplicationDbContext();
    }
}

第二个背景

 public class TestModel : DbContext {
    public TestModel()
        : base("Connection") {
    }
    public virtual DbSet<A> As { get; set; }
    public virtual DbSet<B> Bs { get; set; }
    public virtual DbSet<C> Cs { get; set; }

}

我成功启用了TestModel的迁移并尝试运行

add-migration Initial -ConfigurationTypeName project.Migrations.TestMigrations.Configuration

导致错误

One or more validation errors were detected during model generation:

project.Models.Tests.IdentityUserLogin: : EntityType 'IdentityUserLogin' has no key defined. Define the key for this EntityType.

project.Models.Tests.IdentityUserRole: : EntityType 'IdentityUserRole' has no key defined. Define the key for this EntityType.

IdentityUserLogins: EntityType: EntitySet 'IdentityUserLogins' is based on type 'IdentityUserLogin' that has no keys defined.

IdentityUserRoles: EntityType: EntitySet 'IdentityUserRoles' is based on type 'IdentityUserRole' that has no keys defined.

我无法找到与此问题相关的任何内容，并感谢此处的任何帮助。谢谢。

请检查两个数据库中的主要和外国人密钥约束。首先通过单独连接两个数据库来修复身份约束对于迁移，您也可以使用复制。希望这个暗示能帮到你。
