[API Proposal]: ActivityTraceFlags.RandomTraceId flag #124509

Description

@Kielek

Background and motivation

Needed to comply with new OpenTelemetry specification requirements released as v1.52.0. It was marked as mandatory under open-telemetry/opentelemetry-specification#4761.

RandomTraceId definition is availab;e on W3C page.

It is also needed for open-telemetry/opentelemetry-dotnet#6768

API Proposal

namespace System.Diagnostics;

 [Flags]
public enum ActivityTraceFlags
{
None = 0b_0_0000000,
Recorded = 0b_0_0000001, + RandomTraceId = 0b_0_0000010, // 2
}
public partial class Activity : IDisposable
{
+ public bool RandomizedTraceId { get { throw null; } }
}

API Usage

N/A

Alternative Designs

No response

Risks

Needed to modify also the way how traceId/flags are created by the Activity class.
Worth to double check if System.Diagnostics.W3CPropagator will be able to handle correctly new flag.

                          Needed to modify also the way how traceId/flags are created by the Activity class.
                          Worth to double check if System.Diagnostics.W3CPropagator will be able to handle correctly new flag.

                              [API Proposal]: ActivityTraceFlags.RandomTraceId flag #124509

                              Description

                              @Kielek

                              Background and motivation

                              Needed to comply with new OpenTelemetry specification requirements released as v1.52.0. It was marked as mandatory under open-telemetry/opentelemetry-specification#4761.

                              RandomTraceId definition is availab;e on W3C page.

                              It is also needed for open-telemetry/opentelemetry-dotnet#6768
