hi Hakan

Dashboards functionality changed a bit, so you need to configure it in json or c#, have a look at docs - https://our.umbraco.com/documentation/Extending/Dashboards

Registering with package.manifest Add a file named 'package.manifest' to the app_plugins folder, containing the following json configuration pointing to your dashboard view:

{
    "dashboards":  [
        {
            "alias": "myCustomDashboard",
            "view":  "/App_Plugins/myCustom/dashboard.html",
            "sections":  [ "content", "settings" ],
            "weight": -10
        }
    ]
}

Registering with C# Type By creating a C# class that implements IDashboard from Umbraco.Core.Dashboards then this will automatically be discovered by Umbraco at application startup time.

using System;
using Umbraco.Core.Composing;
using Umbraco.Core.Dashboards;

    namespace My.Website
    {
        [Weight(-10)]
        public class MyDashboard : IDashboard
        {
            public string Alias => "myCustomDashboard";

            public string[] Sections => new[] { "content", "settings" };

            public string View => "/App_Plugins/myCustom/dashboard.html";

            public IAccessRule[] AccessRules => Array.Empty<IAccessRule>();
        }
    }

Thanks,

Alex
