Profiler Preview 0.17

This is the 10th preview release of the Xamarin Profiler. Changes since last release include:

Please note that the Mac app bundle has been renamed (from to "Xamarin"), so the old version needs to be removed before installing this new update, so that Xamarin Studio prompts the user for the new location.

  • Fix metadata retrieval when paused
  • Fix flat chart for Android profiling
  • Support MLPD v10 format
  • Display relative percentages in call tree views


  • Use radio buttons for call tree display settings
  • Fix enabling of console view for live runs
  • Fix resizing of right-side panel view


  • Prettify NSAlert-based dialogs
  • Fix problems with spaces for MLPD directory setting
  • Use radio buttons for snapshots preferences and call tree display settings

This is a preview release and there are definite limitations, including but not limited to:

  • No official support for profiling Release builds
  • Data sets are correct at time of collection but data mining and representation is preliminary. This will improve in future releases.
  • Samples list not available on Android
  • Support for Xamarin.Mac app profiling is preliminary
  • Enabling Boehm for iOS builds results in no useful data on devices, as allocations and calls need to be disabled
  • Performance with large apps has been improved, but still lacking some

We encourage users to get in touch and file bug reports so we can continue to make this tool more useful and more stable.
