I have found a way to make it work by using a redirect as follows...

Inside Startup

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

Inside AccountController

// GET: /Account/CheckSignIn
[HttpGet]
[Authorize]
public IActionResult CheckSignIn()
{
    //add code here to check if AzureAD identity exists in user table in local database
    //if not then insert new user record into local user table

    return RedirectToAction(nameof(HomeController.Index), "Home");
}

//
// GET: /Account/SignIn
[HttpGet]
public IActionResult SignIn()
{
    return Challenge(
        new AuthenticationProperties { RedirectUri = "/Account/CheckSignIn" }, OpenIdConnectDefaults.AuthenticationScheme);
}

Inside AzureAdServiceCollectionExtensions (.net core 2.0)

private static Task RedirectToIdentityProvider(RedirectContext context)
{
    if (context.Request.Path != new PathString("/"))
    {
        context.Properties.RedirectUri = new PathString("/Account/CheckSignIn");
    }
    return Task.FromResult(0);
}
