.NET 7 and UseEndPoints()

Question

I am trying to convert a .NET Core 3.1 project to .NET 7.

When I use this in my Program.cs class:

app.UseEndpoints(endpoints =>
{
    endpoints.MapRazorPages();

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

It gives me this message:

Suggest using top level route registrations UseEndpoints

Then, I clicked on Show potential fixes in Visual Studio and it suggests this:

app.UseEndpoints(endpoints =>
{
    _ = endpoints.MapRazorPages();

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

Which looks the same to me.

In .NET 7, what should I do if I need to use RazorPages()?

Thanks!

Answer 1

AFAIK it should work as is but the warning suggests to register the routes at the top-level of a minimal hosting application, i.e.:

app.MapRazorPages();

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

See the ASP0014: Suggest using top level route registrations code analysis rule.

Oh ok, so I don't need UseEndpoints and I can just change endpoints.MapControllerRoute to app.MapControllerRoute ? Thanks! – Pyosis

@Pyosis yes, exactly. – Terrel

This is what I am using for using endpoints.

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

I hope that helps.

Well actually not really. This question has a good answer. Your answer is just showing the same case the OP originally had. – Spectroscope

There is a difference in the API used and the order of things that matters. I am using Endppoints on app not MapControl on app also the areas should be before the default, and in my case I am showing MapRazor at the end not at first. What was suggested was the ideal way in earlier versions before UseEndpoint was introduced. – Stationmaster

You can use just like that for .net core 8

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

For healthchecks you can use this:

    app.UseRouting();
    app.UseHealthChecks("/health");
    app.UseHealthChecks("/health/ping", new HealthCheckOptions()
    {
        Predicate = (check) => check.Tags.Contains("ping")
    });
