c# - CookieAuthentication cookies are invalid after application pool recycle

Question

I have a .net core project using Microsoft.AspNetCore.Authentication (2.2.0) configured to use CookieAuthentication. Cookies are configured to be persistent and expire after seven days. The problem is that all logged-in users are logged out whenever the application pool is recycled.

I am not using sessions at all. I have verified that the cookie is still present in the web browser, it seems like the existing cookies are determined to be invalid by the server. How can I change this behavior?

This is the current configuration:

services
    .AddAuthentication(CookieAuthenticationDefaults.AuthenticationScheme)
    .AddCookie(
        CookieAuthenticationDefaults.AuthenticationScheme,
        options =>
        {
            options.AccessDeniedPath = "/";
            options.LoginPath = "/";
            options.LogoutPath = "/Authentication/Logout";
            options.Events.OnRedirectToLogin = context =>
            {
                context.Response.Redirect("/?returnUrl=" + context.Request.GetEncodedPathAndQuery());

                return Task.CompletedTask;
            });

错误是 IIS 中的应用程序池配置错误。在应用程序池的“高级设置”中，设置“加载用户配置文件”需要设置为“true”。
