Description Jeremy Kolb 2016-12-07 18:13:30 UTC
The profiler has paths to roots as blank for live objects.

@jkolb, I have checked this issue with latest profiler build i.e. and unable to reproduce this issue.
Could you please attach the sample and profiler log so that I can confirm this issue at our end.

This is with build  It does not appear that is on the Xamarin site.
Comment 5 Jeremy Kolb 2016-12-08 15:29:26 UTC
The project is at https://github.com/inormis/MvxSIGSEVTest
Comment 6 Rodrigo Moya 2016-12-12 13:34:01 UTC
You need to take snapshots (and wait for the application to finish) to see data in the paths to roots section, as that's where object references are reported by the runtime. So:

* start profiling your app
* take as many snapshots as you want
* stop application

After that, you should see data for alive objects
Comment 7 Jeremy Kolb 2016-12-12 15:01:22 UTC
Even with snapshots via GC (example if I set it to snapshot on every GC or every 10 seconds) it does not work.
Comment 8 Jeremy Kolb 2016-12-12 15:01:47 UTC
Manual snapshots are not possible.  See Bug 49319.
Comment 9 Rodrigo Moya 2017-02-02 19:12:58 UTC
this should be fixed now in the upcoming C9 refresh (1.1.8), so closing for now, please reopen if it happens again for you.

I have checked this issue with latest profiler build i.e. and  observed that this issue is working fine.


Now I am closing this issue.
