I want to set Login Page as Default page.Login page is present in Area Folder

The easiest way is to configure default values for area, controller and action:

    app.UseMvc(routes =>
    {
        routes.MapRoute(
            name: "default",
            template: "identity/{controller=Account}/{action=Signin}");

        routes.MapRoute(
              name: "areaRoute",
              template: "{area:exists}/{controller}/{action}"
            );
        routes.MapRoute(
            name: "areaRoute",
            template: "{area=Identity}/{controller=Account}/{action=Signin}"
        );
    });

Controller code : Need to Remove Route parameter

    [Area("Identity")]        
    public class AccountController : BaseController
    {
        private readonly UserManager<ApplicationUser> _userManager;
        private readonly SignInManager<ApplicationUser> _signInManager;


        public AccountController(
         UserManager<ApplicationUser> userManager,
         SignInManager<ApplicationUser> signInManager
         )
        {
            _userManager = userManager;
            _signInManager = signInManager;
        }


        // GET: /Account/SignIn            
        [HttpGet]
        [AllowAnonymous]
        public async Task<IActionResult> SignIn(string returnUrl = null)
        {                
            return View();
        }
    }
