TraceEvent - no events received when first EnableProvider call has EventIDsToEnable options

[christian-clausen]

Hi there,

During testing, we noticed some unexpected behaviour when trying to enable a provider with EventIDsToEnable options.

Our scenario is this:

1. Enable provider with EventIDsToEnable = event 1 and 3
2. Start processing
3. Generate events 1, 2, and 3

We excepted to receive manifest and events 1 and 3, but the actual outcome was that we received no events at all.

We have made a repro of issue here: https://github.com/observito/ProviderOptionsRepro. We found a small workaround, which we also included in the repro: First we run with workaround:true and we RECEIVE events 1 and 3. Then -- after you press a key -- we run 'normal mode' and do not receive any events.

Are we doing something wrong or is this a bug?

Best regards,
