[SOLVED] Unable to find assembly System.Diagnostics.DiagnosticSource when using SqlDependency with SignalR in Multiple Projects

I have two asp.net MVC Projects in one solution. AdminPanel and Web. I need to show notifications using signalR and whenever a notification table is updated. I am using SqlDependency with signalR for this. The Web Project runs fine but the Admin Project gives me this Error

Unable to find assembly 'System.Diagnostics.DiagnosticSource, Version=4.0.2.1, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51'.

Here is the implimentation

Owin Startup

[assembly: OwinStartup("Startup", typeof(Startup))]
namespace Admins.Hubs
{
    public class Startup
    {
        public void Configuration(IAppBuilder app)
        {
            var idProvider = new CustomUserIdProvider();
            GlobalHost.DependencyResolver.Register(typeof(IUserIdProvider), () => idProvider);
            app.MapSignalR();
            SqlDependency.Start(Connection.ConnectionString);

            var properties = new AppProperties(app.Properties);
            CancellationToken token = properties.OnAppDisposing;
            if (token != CancellationToken.None)
            {
                token.Register(() =>
                {
                    SqlDependency.Stop(Connection.ConnectionString);
                });
            }
        }
    }
}

This one Startup File is being used by both projects

this is my messagehandler class

public class MessagesRepository
{
    readonly string _connString = Connection.ConnectionString;
    public IEnumerable<NotificationMessage> GetAllMessages()
    {
        var messages = new List<NotificationMessage>();
        using (var connection = new SqlConnection(_connString))
        {
            connection.Open();
            using (var command = new SqlCommand(@"SELECT [ID],[Title],[Description],[MessageType],[NotificationType],[Icon],[IsAjaxMessage],[IsViewMessage],[IsRedirectMessage] FROM [General].[NotificationMessage]", connection))
            {
                command.Notification = null;
                var dependency = new SqlDependency(command);
                dependency.OnChange += new OnChangeEventHandler(dependency_OnChange);
                if (connection.State == ConnectionState.Closed)
                    connection.Open();
                var reader = command.ExecuteReader();
                while (reader.Read())
                {
                    messages.Add(new NotificationMessage(reader));
                }
            }
        }
        return messages;
    }



    public virtual void dependency_OnChange(object sender, SqlNotificationEventArgs e)
    {
        if (e.Type == SqlNotificationType.Change)
        {
            IHubContext context = GlobalHost.ConnectionManager.GetHubContext<Notification>();
            context.Clients.All.GetNotifications();
        }
    }
}

This all is working fine. Except this is only working Fine in Web Project and Not in Admin Project.
