Hi.
Thanks again for your reply.
I set priority in RouteProvider to -100 or 10 or 1. but yet can't work.

My Dependency Register is:

    public class CustomDependencyRegister : IDependencyRegistrar
    {
        private const string ContextName = "nop_object_context_Sample";
        public int Order => 999;

        public void Register(ContainerBuilder builder, ITypeFinder typeFinder, NopConfig config)
        {                 
            builder.RegisterType<CustomHomeAdminController>)
.As<Nop.Web.Areas.Admin.Controllers.HomeController>();
        }
    }

Hi every body.
Finally, this route resolve my problem:

            routeBuilder.MapAreaRoute(
                name: "Nop.Plugin.Misc.Sample.CustomHomeAdmin",
                areaName: AreaNames.Admin,
                template: "Admin/{controller=CustomHomeAdmin}/{action=CustomIndex}/{id?}");

But notice its performance lags!

For redirect to custom view,solution is:

return View("~/Plugins/Misc.Sample/Views/CustomHomeAdmin/CustomIndex.cshtml", model);

Other issue is that,Whether there is a way that the instead of using above code,
This code is used?

return View("CustomIndex", model);

My CustomViewLocationExpander is:

    public class CustomViewLocationExpander : IViewLocationExpander
    {
        public void PopulateValues(ViewLocationExpanderContext context)
        {
        }

        public IEnumerable<string> ExpandViewLocations(ViewLocationExpanderContext context, IEnumerable<string> viewLocations)
        {


                viewLocations = new[] {
                            $"~/Plugins/Misc.Sample/Views/{{1}}/{{0}}.cshtml",
                            $"~/Plugins/Misc.Sample/{{0}}.cshtml"
                        }
                        .Concat(viewLocations);

            return viewLocations;
        }

CustomStartup:

    public class CustomStartup : INopStartup
    {
        #region Implementation of INopStartup
        public void ConfigureServices(IServiceCollection services, IConfigurationRoot configuration)
        {
            //themes support
            services.Configure<RazorViewEngineOptions>(options =>
                                                       {
       options.ViewLocationExpanders.Add(new CustomViewLocationExpander());
                                                       });            
        }

        public void Configure(IApplicationBuilder application)
        {
            
        }

        public int Order => 0;
        #endregion
    }

When I Use this:

return View("CustomIndex", model);

Cause an error to be,

But this code works:

return View("~/Plugins/Misc.Sample/Views/CustomHomeAdmin/CustomIndex.cshtml", model);

Where is my problem? Please advice me.

Thanks

[Best Regards]
