In global.asax Application_Start start a timer. When the timer fires use HostingEnvironment.QueueBackgroundWorkItem to call a function that does the DB-Query and notification via SignalR

void Application_Start(object sender, EventArgs e)
    var backgroundTimerTenMinutes = new System.Timers.Timer(600000);
    backgroundTimerTenMinutes.Elapsed += backgroundTimerTenMinutes_Elapsed;

void backgroundTimerTenMinutes_Elapsed(object sender, System.Timers.ElapsedEventArgs e)
    HostingEnvironment.QueueBackgroundWorkItem(ct => DBQueryAndNotify(ct));
