我们正在尝试使用 Microsoft 身份验证.当我运行该应用程序并使用 Microsoft 帐户登录时，该应用程序在此行上的 AccountController ExternalLoginCallback 中爆炸
We are trying to use Microsoft authentication. When I run the app and login using Microsoft Account then the app blows up in the AccountController ExternalLoginCallback on this line
var result = await _signInManager.ExternalLoginSignInAsync(info.LoginProvider, info.ProviderKey, isPersistent: false);
错误是
Cannot use table 'AspNetUsers' in schema '' for entity 'AspNetUsers' since it is being used for another entity.
除了CustomersContext 没有其他dbContext.除了 ApplicationUser，我找不到任何映射到 AspNetUsers 的实体.
There is no other dbContext other than CustomersContext. I can't find any entities mapping to AspNetUsers other than ApplicationUser.
没有迁移.如果我尝试创建初始迁移，也会发生同样的错误.
There are no migrations. The same error also occurs if I try to create an initial migration.
dnx ef migrations add initial
对于包含的代码数量，但没有包含任何关键信息而道歉.
Apologies for the amount of code included and yet not including that critical piece of information whatever it is.
推荐答案
当你继承自 IdentityDbContext 时，你不需要重新创建 AspNet* DbSet，只需添加你的新桌子.
您的 CustomersContext 应如下所示:
As you inherit from IdentityDbContext, you don't need to recreate AspNet* DbSet, just add your new table.
Your CustomersContext should look like that:
public partial class CustomersContext : IdentityDbContext<ApplicationUser>
{
protected override void OnConfiguring(DbContextOptionsBuilder options)
{
options.UseSqlServer(@"Server=(localdb)\mssqllocaldb;Database=Customers;Trusted_Connection=True;MultipleActiveResultSets=true");
}
protected override void OnModelCreating(ModelBuilder modelBuilder)
{
base.OnModelCreating(modelBuilder);// we have to do this because we are inheriting from IdentityDbContext<ApplicationUser> not DbContext
// override the users tables with your properties
modelBuilder.Entity<ApplicationUser>(entity =>
{
entity.HasIndex(e => e.BusinessName).HasName("BusinessNameIndex");
entity.HasIndex(e => e.NormalizedEmail).HasName("EmailIndex");
entity.HasIndex(e => e.NormalizedUserName).HasName("UserNameIndex");
entity.Property(e => e.Id).HasMaxLength(450);

public virtual DbSet<ReferralSources> ReferralSources { get; set; }
public virtual DbSet<Referrals> Referrals { get; set; }
public virtual DbSet<Subscriptions> Subscriptions { get; set; }
}
或者不调用base.OnModelCreating就可以完全创建模型，复制OnModelCreating来自源代码
Or you can completely create the model without calling base.OnModelCreating, you can copy the OnModelCreating from the source code
