mvc core2.0 routing is not Workin - asp.net-core-mvc

Question

Here i'm new to mvc core2.0 please help me why my Routing Is not working
My Routing Class
public static class ApplicationRoteProfiler
{
public static void Routeing(IRouteBuilder builder)
{
builder.MapRoute("route1", "", new
{
Controllers = "Department",
Action = "Add",
});
builder.MapRoute("route2", "Department/Add", new
{
Controllers = "Department",
Action = "Index"
});
}
This class file i register in startup.config file
public void Configure(IApplicationBuilder app)
{
app.UseStaticFiles();
app.UseMvc();
app.UseMvcWithDefaultRoute();
app.UseMvc(routes =>
{
ApplicationRoteProfiler.Routeing(routes);
});
}
When i hit my server as http://localhost:1588/Department/Add its should redirect to Department/Index But its hitting Department/Add

Answer 1

Should it be just Controller not Controllers??
builder.MapRoute("route1", "", new { controller = "department", action = "index" });
My 2 cents
You shouldn't use app.UseMvcWithDefaultRoute() and app.UseMvc() at the same time. You only need to pick 1 of them.
I don't see benefits of using a static class to configure routing for MVC. You can just put all the route configurations right there inside UseMvc lamba function. Also I don't think you need to put customized route specifically for your "route1" as it follows the standard MVC routing convention.
app.UseMvc(routes =>
{
// The order of these routes matters!
routes.MapRoute(
name: "route2",
template: "department/add",
defaults: new { area = "", controller = "department", action = "index" });
routes.MapRoute(
name: "default",
template: "{controller=home}/{action=index}/{id?}");
}
You can also return RedirectToAction("index"); inside your Department controller Add method so whenever /deparment/add route is hit, it redirects to /deparment/index, assuming you have the default MVC routing setup, either use the "default" route I put on #2, or use UseMvcWithDefaultRoute(). That way you don't need to create custom routes just for redirecting.
public class DepartmentController : Controller
{
public IActionResult Index()
{
return View();
}
public IActionResult Add()
{
return RedirectToAction("index");
}
}
