即使在asp.net核心2.2中使用PasswordSignInAsync成功登录后，User.Identity.IsAuthenticated也始终返回false

services.AddAuthentication(CookieAuthenticationDefaults.AuthenticationScheme)
    .AddCookie(options =>
    {
        options.Cookie.Name = "YourCookieName";
        options.LoginPath = "/Account/Login";
    });

app.UseRouting();

app.UseAuthentication();
app.UseAuthorization();

// ...

[HttpPost]
public async Task<IActionResult> Login(LoginViewModel model)
{
    if (ModelState.IsValid)
    {
        var result = await _signInManager.PasswordSignInAsync(model.Username, model.Password, model.RememberMe, lockoutOnFailure: false);
        if (result.Succeeded)
        {
            return RedirectToAction("Index", "Home");
        }
        else
        {
            ModelState.AddModelError(string.Empty, "Invalid login attempt.");
        }
    }
    return View(model);
}

await _signInManager.SignInAsync(user, isPersistent: false);
