C# 构建数据库后，Guid不是外键。ASP.NET核心标识3.1

我在这里使用ASP.NET标识，但我有一些问题，我想用一些属性扩展它。我添加了类应用程序user，它继承自identity用户

public class UserInfo : IdentityUser 
{
    public virtual UserProfileInfo ProfileInformation { get; set; }
}

public class UserProfileInfo 
{
    [Key]
    public int Id { get; set; }
    public string FirstName { get; set; }
    public string LastName { get; set; }
}

My

DbContext

：

public class MISDBContext : IdentityDbContext<UserInfo> 
{
    public MISDBContext(DbContextOptions<MISDBContext> options)
        : base(options) { }

    public DbSet<MISObject> MISobject { get; set; }
    public DbSet<ApplicationUser> AppUsers { get; set; }

    protected override void OnModelCreating(ModelBuilder modelBuilder) 
    {
        base.OnModelCreating(modelBuilder);
    }
}

我的Startup.cs

public void ConfigureServices(IServiceCollection services) {
     services.AddDbContext<MISDBContext>
      (options => options.UseSqlServer(Configuration.GetConnectionString("DefaultConnection")));
        services.AddDbContext<ApplicationDbContext>(options =>
            options.UseSqlServer(
                Configuration.GetConnectionString("DefaultConnection")));
        services.AddDefaultIdentity<IdentityUser>(options => options.SignIn.RequireConfirmedAccount = true)
            .AddEntityFrameworkStores<ApplicationDbContext>();
             
        services.AddControllersWithViews();
        services.AddRazorPages();
    }

public void配置服务（IServiceCollection服务）{
services.AddDbContext
（options=>options.UseSqlServer（Configuration.GetConnectionString（“DefaultConnection”））；
services.AddDbContext

public void ConfigureServices(IServiceCollection services) {
     services.AddDbContext<MISDBContext>
      (options => options.UseSqlServer(Configuration.GetConnectionString("DefaultConnection")));
        services.AddDbContext<ApplicationDbContext>(options =>
            options.UseSqlServer(
                Configuration.GetConnectionString("DefaultConnection")));
        services.AddDefaultIdentity<IdentityUser>(options => options.SignIn.RequireConfirmedAccount = true)
            .AddEntityFrameworkStores<ApplicationDbContext>();
             
        services.AddControllersWithViews();
        services.AddRazorPages();
    }
