Do I need services.AddMvc or not?

Question

I'm trying to find out why in all docs I see services.AddMvc or services.AddMvcCore in Startup.cs but in ASP.NET Core MVC 3.1 template that's created by VS I do not have AddMvc but mvc still works....

the only thing I have related t MVC is

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

can anyone explain why?

I think all the docs you are seeing is for .net core 2.*. https://learn.microsoft.com/en-us/aspnet/core/migration/22-to-30?view=aspnetcore-2.2&tabs=visual-studio — Manish, Jan 03 '20 at 03:14

As the doc has said that asp.net core 3.0+ template use these new methodsAddControllersWithViews,AddRazorPages,AddControllers instead of AddMvc.

However, AddMvc continues to behave as it has in previous releases.AddMvc() is really just a wrapper around a bunch of other methods that register services. See Source:

https://github.com/aspnet/AspNetCore/blob/0303c9e90b5b48b309a78c2ec9911db1812e6bf3/src/Mvc/Mvc/src/MvcServiceCollectionExtensions.cs#L27

You could either use AddMvc to register for MVC, Razor Pages,API or use individual AddControllersWithViews(for MVC only) and AddRazorPages (for Razor Pages only).

What would you do if you have a mixture of mvc, razor pages and web api endpoints? — Rez.Net, Aug 12 '20 at 22:58
