Applnsights GetMetric not working using the telemetry client added by the SDK

[stephenschwan]

Please provide a succinct description of the issue.

Use the TrackMetric via MetricIdentifier. Metrics are not being published / not showing up in the app insights portal.

If you just use the ActiveTelemetry channel for example, it works as expected. But if you use the one registered via the SDK in the ServiceCollection, metrics are not collected.

Traces, dependencies and exceptions work as expected, just not metrics.

Provide the steps required to reproduce the problem

1. Use the SDK to add App Insights

 .ConfigureLogging(loggingBuilder =>
{
        loggingBuilder.SetMinimumLevel(Extensions.Logging.LogLevel.Debug);
        loggingBuilder.AddApplicationInsights(options =>
        {
              options.InstrumentationKey = "....";
         });
})

2. Use said telemetry client to track metrics

public virtual void TrackMetric(MetricIdentifier identifier, double value, string dimension1Value, string dimension2Value)
{
       Metric metric = GetClient().GetMetric(identifier);
       metric.TrackValue(value, dimension1Value, dimension2Value);
 }

Expected behavior

Metrics to be tracked

Actual behavior

Nothing is logged or visible in the AI portal

Known workarounds

Use your own telemetry client
