Disabling Recording of an Activity (span) in .NET OpenTelemetry Instrumentation

This technical article details a method for conditionally disabling the recording and export of an Activity (span) in .NET's OpenTelemetry-compatible instrumentation. It addresses a specific use case in ASP.NET Core middleware where, for performance or cost reasons, you might want to programmatically prevent certain spans (like those from a known callback URL) from being sampled and exported, even within a sampled trace.
