[BUG] AzureMonitor doesn't capture activities/spans/dependencies about azure-sdk-for-net

[cijothomas]

The repro shared is not adding builder.Services.ConfigureOpenTelemetryTracerProvider((sp, builder) => builder.AddSource("test"));
Could you add that and try again?

There's three ways to use the using keyword:

1. using with a block

   using (new SomeClass())
   {
       // do some work
   }
   

2. using with a block (shorthand)

   using (new SomeClass());
   // do some work
   

3. using with a declared variable.

   using var someClass = new SomeClass();
   // do some work
   

In your code sample, you're using option 2.
So your activity is disposed after the LogInformation.
Your activity does not encompass the dependency call to bing.

You're right! Thanks!

However, when I did that, my custom activity did showed up but the activity duration seemed to be off.

I'd expect it to include the duration of the request to https://www.bing.com/.

Thank you so much!

I figured it out why my traces were not showing up in ApplicationInsights. It's because I had the SamplingRatio set to 0.05. I'd recommend anyone who is testing their telemetry pipeline end-to-end to not set the SamplingRatio.
