1.check you have configured routing in startup.cs:

app.UseRouting();


            ...
            app.UseEndpoints(endpoints =>
            {

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

2.Check if your routing exists.For example,routing of Index in your code is

https://localhost:xxx/Habitats/Index

3.Check if your corresponding view is in the correct location.For example the view of Index should in Views/Habitats,and the name should be Index.cshtml.
