Unable to get ApplicationInsights to trace

Question

I've created a new Azure Web job, a new Application Insights resource, and am simply trying to get one to log to the other. As I understand it, it should be as straight-forward as adding the appropriate NuGet packages, and adding some code along these lines:

TelemetryClient tc = new TelemetryClient();
tc.InstrumentationKey = "my-key";
tc.TrackEvent("testing");
tc.TrackTrace("test diag");
tc.Flush();
System.Threading.Thread.Sleep(1000);

The sleep is there because I found this MS article that suggested it might be needed. This code happens as the web job fires up (so effectively, it's just a console app). However, when I run it, I get no metrics whatsoever.

I've tried putting the key in the ApplicationInsights.config, but that makes no difference. I've also tried different types of logging, including exceptions.

My guess is that the code above isn't doing what I think it is, but I'd be grateful if someone could point me in the right direction as to why.

I can track user events by inserting TrackEvent calls in Azure Webjobs function code, the following sample works fine on my side, you can refer to it.
