            app.UseStaticFiles();

            // app.UseAuthentication(); // not needed, since UseIdentityServer adds the authentication middleware
            app.UseIdentityServer();

            app.UseMvc(routes =>
            {
                routes.MapRoute(
                    name: "default",
                    template: "{controller=Home}/{action=Index}/{id?}");
            });
        }
    }
}

这就是我运行此活动指示器的方式,也就是这样启动运行活动指示器的方法:this.IsBusy = true;

但我看不到
