Hey create an IdentityConfig in App_Start folder and add below code.
using System;
using System.Security.Claims;
using System.Threading.Tasks;
using Microsoft.AspNet.Identity;
using Microsoft.AspNet.Identity.EntityFramework;
using Microsoft.AspNet.Identity.Owin;
using Microsoft.Owin;
using Microsoft.Owin.Security;
using BookerDataSync.Models;

namespace test
{
    // Configure the application user manager used in this application. UserManager is defined in ASP.NET Identity and is used by the application.
    public class ApplicationUserManager : UserManager
    {

            : base(store)
        {
        }

        public static ApplicationUserManager Create(IdentityFactoryOptions options, IOwinContext context)

            manager.UserValidator = new UserValidator(manager)
            {

                RequireUniqueEmail = true

            // Configure validation logic for passwords
            manager.PasswordValidator = new PasswordValidator

check this
https://stackoverflow.com/questions/49609299/applicationsigninmanager-not-found-asp-net-mvc
applicationsigninmanager inherits from SignInManager(this from Microsoft.AspNetCore.Identity dll)
https://docs.microsoft.com/en-us/dotnet/api/microsoft.aspnetcore.identity.signinmanager-1?view=aspnetcore-3.1
check for ApplicationUserManager class inherits from UserManager class from (Microsoft.AspNet.Identity) dll
ApplicationRoleManager class inhirts from RoleManager class from (Microsoft.AspNet.Identity) dll
https://www.pluralsight.com/guides/configuring-asp-net-identity

check path of these dll at reference under solution if it is empty please re-add and build it.
