Description
There was a recent regression in AsyncCausalityTracer when WinRT supported was removed via #36715. This causes TplEventSource/Operation/Start and TplEventSource/Operation/Stop events to stop firing.
This was found while investigating a different issue reported from VS where these events were never being fired on Linux. The reason is because the removed AsyncCausalityTracer depended on COM interop so it was excluded from the build on non-Windows platforms.
This item tracks implementing cross-platform AsyncCausalityTracer so that both problems described above can be addressed.
