How to do custom routing in ASP.NET Core 3.1 MVC

Question

I can't use simple routing like in .NET Core 2.2 in .NET Core 3.1.

What is the routing last change in .NET Core 3.1?

Answer 1

In .NET 3 you should use Endpoint instead of Routing

app.UseStaticFiles();
app.UseRouting();
//other middleware

app.UseEndpoints(endpoints =>
{
    endpoints.MapControllers();
    endpoints.MapRazorPages();
    endpoints.MapHub<MyChatHub>();
    endpoints.MapGrpcService<MyCalculatorService>();
    endpoints.MapControllerRoute(name: "default", pattern: "{controller=Home}/{action=Index}/{id?}");
});
