SQL Server 到 postgres - 未创建身份表

Question

我开发了一个连接到 SQL Server 数据库的 ASP.NET Core MVC 应用程序。现在，我按照以下步骤将目标数据库更改为 PostgreSQL

• 步骤 #1 - 更改连接字符串

• 步骤 #2 - 将

  .HasColumnType("INTEGER")

  替换为

  .HasColumnType("BOOLEAN")

• 步骤#3 - 运行命令

  dotnet ef database update

但只创建了

__EFMigrationsHistory

表。

AspNetRoleClaims, AspNetRoles, AspNetUserClaims

以及其他所需的表未创建。

我怀疑这段代码有问题：

var builder = WebApplication.CreateBuilder(args);
var connectionString = builder.Configuration.GetConnectionString("DefaultConnection") ?? throw new InvalidOperationException("Connection string 'IdentityContextConnection' not found.");

builder.Services.AddDbContext<IdentityContext>(options => options.UseNpgsql(connectionString));

builder.Services.AddDefaultIdentity<ApplicationUser>(options => options.SignIn.RequireConfirmedAccount = false)
  .AddEntityFrameworkStores<IdentityContext>();

这些是我的包裹
