.NET Core 6.0 Routing is Not working if i use areas

Question

I have project with areas and normal controller in it. But Area routing is working but normal controller is not working.

Working, but Areas routing is returning 404 :

app.MapControllerRoute(
    name: "default",
    pattern: "{controller=Home}/{action=Index}/{id?}");

Working for Area routing but not root controller :

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

I have other 3 project with same scenarios but that are working but facing issue with my recently created project.

You have to specify two routes with different names.

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

app.MapControllerRoute(
    name: "default",
    pattern: "{controller=Home}/{action=Index}/{id?}"
);

After that you have to use [Area] attribute to specify which Controller belongs to which Area.

 [Area("Admin")]
