In member bool MetricIdentifier.Equals(object otherObj), change parameter name otherObj to obj in order to match the identifier as it has been declared in bool object.Equals(object obj) (https://learn.microsoft.com/dotnet/fundamentals/code-analysis/quality-rules/ca1725)

In member void OperationCorrelationTelemetryInitializer.Initialize(ITelemetry telemetryItem), change parameter name telemetryItem to telemetry in order to match the identifier as it has been declared in void ITelemetryInitializer.Initialize(ITelemetry telemetry) (https://learn.microsoft.com/dotnet/fundamentals/code-analysis/quality-rules/ca1725)

'active == null' is always 'true'. Remove or refactor the condition(s) to avoid dead code. (https://learn.microsoft.com/dotnet/fundamentals/code-analysis/quality-rules/ca1508)
