I have updated my blog entry on collecting ETW data on an ARM WinRT device.   Previously I told you to use the WPR's 'GeneralProfile' to collect the data.  This is OK for some investigations, but does not collect all the same events that PerfView would have collected (most notably GC events, JIT compile events and async Task Events).    We have created a DotNetRuntimeProfile.wprp, that will tell WPR to collect these extra events.  See the posting for more details.   I do recommend this if you need to collect ETW for managed code applications on the ARM device.
