How to consume and process events at metro Apps?

Question

How to consume and process events  at metro Apps?

the following APIs only apply to desktop, but how can I use at metro apps?

OpenTrace/CloseTrace/ProcessEvent?

as we know, the APIs of controlling events and providing event can be used at metro and desktop apps, for example, StartTrace, EnableTrace, ControlEvent, Register/TraceEvent/, some like that.

============================

there is another question about ETW:
1. When provider send event tracing log by TraceEvent or EventWrite, can controller monitor it real-time? as we know, there are StartTrace/EnableTrace/ControlTrace APIs in controller.

Answer 1

Those three are not available in Metro style apps. If you have a scenario where the lack of these are blocking your progress, please let us know. You can also email me directly DavidLam AT Microsoft DOT com.

thank you David.

because I try to using ETW to implement duplex communication between the metro apps and desktop apps, then I found that don't work from desktop to metro.
