У меня есть веб-приложение ASP.NET Core с логинами AspNetCore.Identity. Он использует SQL Server для аутентификации пользователя.
Мне нужно использовать базу данных PostgreSQL. Я добавил несколько пакетов nuget (EF. * И т. Д.), Изменил строку подключения и код
public void ConfigureServices(IServiceCollection services)
{
services.Configure<CookiePolicyOptions>(options =>
{
// This lambda determines whether user consent for non-essential cookies is needed for a given request.
options.CheckConsentNeeded = context => true;
});
// options.UseSqlServer( Configuration.GetConnectionString("DefaultConnection")));
services.AddDbContext<ApplicationDbContext>(options =>
options.UseNpgsql( Configuration.GetConnectionString("DefaultConnection")));
services.AddDefaultIdentity<IdentityUser>()
.AddEntityFrameworkStores<ApplicationDbContext>();
services.AddControllersWithViews()
.AddNewtonsoftJson();
services.AddRazorPages();
}
Но когда я его запускаю, он подключается кБаза данных PostgreSQL и пытается создать структуру я получаю сообщение об ошибке, что не так? Почему EF не может создать структуру? Как решить эту проблему?
