Startup.cs System.Threading.Timer.

// add the below into your Startup contructor
public Startup(IHostingEnvironment env)
{
    // [...]
    var t = new System.Threading.Timer(doSomething);
    // do something every 15 seconds
    t.Change(0, 15000);
}

// define a DateTime property to hold the last executed date
public DateTime LastExecuted { get; set; }

// define the doSomething callback in your Startup class
private void doSomething(object state)
{
    System.Diagnostics.Debug.WriteLine("The timer callback executes.");

    // this callback is called every 15 seconds
    // but the condition below makes sure only it
    // only takes place at 17:00 
    // every day, when LastExecuted is not today
    if(DateTime.UtcNow.Hour == 17 && DateTime.UtcNow.Minute == 0 && DateTime.UtcNow.Date != LastExecuted.Date)
    {
        LastExecuted = DateTime.UtcNow;
        System.Diagnostics.Debug.WriteLine("#### Do the job");
    }
}
