MVC Core 5 Redirect from root controller to Area controller

Question

I have a login controller which is at root level and after successful login I want to redirect the user to a controller inside Area.

I tried below code but it didn't work.

return RedirectToAction("Dashboard", "Home", new { Area = "StaffAug"});

it's redirecting to Home/Dashboard?area=StaffAug instead of StaffAug/Home/Dashboard

Answer 1

The area configuration must come first. See the official docs.

 app.UseEndpoints(endpoints =>  
 {  
      endpoints.MapControllerRoute(  
        name: "areas",  
        pattern: "{area:exists}/{controller=Home}/{action=Index}"  
      );  
        
     endpoints.MapControllerRoute(  
         name: "default",  
         pattern: "{controller=Login}/{action=Index}"  
     );  
 });  

Or

 app.UseEndpoints(endpoints =>  
 {  
     endpoints.MapAreaControllerRoute(  
         name: "StaffAug",  
         areaName: "StaffAug",  
         pattern: "StaffAug/{controller=Home}/{action=Dashboard}"  
     );  
       
          endpoints.MapControllerRoute(  
         name: "default",  
         pattern: "{controller=Login}/{action=Index}"  
     );  
 });  

Also, you did not include the Id route parameter which might cause you issues later.

The code you shared works perfectly on my end. My best guess is there is a problem with your area configuration. Is there anyway you can share example code that illustrates this issue so the community is not forced to guess?

Areas for controllers with views

The Startup.cs file with areas configured according to the doc above.

app.UseEndpoints(endpoints =>  
{  
    endpoints.MapControllerRoute(  
        name: "MyArea",  
        pattern: "{area:exists}/{controller=Home}/{action=Index}/{id?}");  
  
    endpoints.MapControllerRoute(  
        name: "default",  
        pattern: "{controller=Home}/{action=Index}/{id?}");  
});  

Controller with the area attribute.

[Area("StaffAug")]  
public class DashboardController : Controller  
{  
    public IActionResult Index()  
    {  
        return View();  
    }  
}  

Caller

public IActionResult Index()  
{  
    return RedirectToAction("Index", "Dashboard", new { area = "StaffAug" });  
}

My Startup.cs file is below.

app.UseEndpoints(endpoints =>
                {
                    endpoints.MapControllerRoute(
                        name: "default",
                        pattern: "{controller=Login}/{action=Index}"
                    );

                    endpoints.MapControllerRoute(
                       name: "areas",
                       pattern: "{area:exists}/{controller=Home}/{action=Index}"
                     );

                    endpoints.MapAreaControllerRoute(
                        name: "StaffAug",
                        areaName: "StaffAug",
                        pattern: "StaffAug/{controller=Home}/{action=Dashboard}"
                    );
                });

My controller code is below

[Area("StaffAug")]
    public class HomeController : Controller
    {
        private readonly ILogger<HomeController> _logger;

        public HomeController(ILogger<HomeController> logger)
        {
            _logger = logger;
        }

        public IActionResult Dashboard()
        {
            return View();
        }
  }

Caller code

 public class LoginController : Controller
    {
        private readonly VMSDBContext _context;

        public LoginController(VMSDBContext context)
        {
            _context = context;
        }

         [HttpPost]
        public IActionResult Index()
        {

               return RedirectToAction("Dashboard", "Home", new { area = "StaffAug"});

          }          
     }
