Symptom

Instrumentation library - OpenTelemetry.Instrumentation.AspNet
Class - AspNetInstrumentationOptions
Method - Enrich

When Enrich method calls for StopActivity Event, any tags added in this method is not being exported (including http.statusCode tag which is auto collected by this instrumentation library).
`private void ConfigureAspNetInstrumentation(AspNetInstrumentationOptions aspNetInstrumentationOptions)
{
aspNetInstrumentationOptions.RecordException = true;

aspNetInstrumentationOptions.Enrich = (activity, eventName, obj) =>
{
	if (eventName.Equals("OnStopActivity"))
	{
		activity.SetTag("stopactivityeventtest", true);
	}
};

What is the expected behavior?
`private void ConfigureAspNetInstrumentation(AspNetInstrumentationOptions aspNetInstrumentationOptions)
{
aspNetInstrumentationOptions.RecordException = true;

aspNetInstrumentationOptions.Enrich = (activity, eventName, obj) =>
{
            if (eventName.Equals("OnStopActivity"))
	{
		activity.SetTag("stopactivityeventtest", true);
	}
};

stopactivityeventtest tag should be exported to geneva.
http.statusCode tag (which is auto collected by this instrumentation library before this methods calls) should be exported to geneva.

What is the actual behavior?

stopactivityeventtest tag is not exporting to geneva.
http.statusCode tag (which is auto collected by this instrumentation library before this methods calls) is not exporting to geneva.

The title of the issue is misleading. This has nothing to do with any exporter.
