The tap tempo app (transmitter app) uses the console and I've checked the timing against MIDI-OX and found it reliable. the console window does not have to be real time. Here is the code. Note that _PreciseUtcNowTicks is just getting a high resolution value for the system ticks like you can get from stopwatch. i'd use stopwatch but i think it can drift on some machines, based on what i've read. Note how most of this is a tight loop.

const int MIN_TEMPO = 50;
const int MAX_MSG_COUNT = 100;
Console.Error.WriteLine("Press escape to exit. Any other key to tap tempo");
using (var dev = MidiDevice.Outputs[1])
{
	dev.Open();
	long oldTicks = 0;
	var amnt = 0d;
	var next = 0L;
	var dif = 0L;
	var msgCount = 0;
	while (true)
	{
		if (0 != oldTicks)
		{
			var dif2 = (_PreciseUtcNowTicks - oldTicks);
			var tpm = TimeSpan.TicksPerMillisecond * 60000;
			var amnt2 = tpm / (double)dif2;
			if (amnt2 < MIN_TEMPO)
			{
				oldTicks = 0;
				Console.Error.WriteLine("Tap tempo timed out for tempo less than " + MIN_TEMPO + "bpm");
			}
		}
		if (Console.KeyAvailable)
		{
			if (ConsoleKey.Escape == Console.ReadKey(true).Key)
				return; // exit

			if (0 == oldTicks)
			{
				Console.Error.WriteLine("Tap Started");
				oldTicks = _PreciseUtcNowTicks;
			}
			else
			{
				dif = _PreciseUtcNowTicks - oldTicks;
				var ts = new TimeSpan(dif);
				var ms = ts.TotalMilliseconds;
				var tpm = TimeSpan.TicksPerMillisecond * 60000;
			
				amnt = tpm / (double)dif;
				oldTicks = _PreciseUtcNowTicks;
				Console.Error.WriteLine("Tapped @ " + amnt+"bpm "+ms+"ms");
				next = _PreciseUtcNowTicks + (dif/24);
				dev.Send(new MidiMessageRealTimeTimingClock());
				msgCount=0;
			}
						
		}
		else
		{
			if (MAX_MSG_COUNT > msgCount && 0 != next && _PreciseUtcNowTicks >= next)
			{
				next += dif / 24;
				dev.Send(new MidiMessageRealTimeTimingClock());
				++msgCount;
			}
		}
	}
}
