Activity id of nettrace events are always 0

[Grégoire]

Description

I noticed in all the nettrace collected from prod, all the ActivityId are RelatedActivityId are 0. One of the consequence is that the RequestStart/Stop events from ASP.NET Core can't be correlated.

Reproduction Steps

var builder = WebApplication.CreateBuilder(args);
var app = builder.Build();
app.MapGet("/", () => { });
app.Run();

2. dotnet trace collect --process-id $PID --providers Microsoft-AspNetCore-Server-Kestrel --clreventlevel verbose
3. Open the nettrace and observe that all ActivityId are equal to Guid.Empty

Expected behavior

I would expect to have non-0 ActivityId to correlate requests.

Actual behavior

All ActivityIds are 0.
