Profiler Preview 0.33.0

Another preview release of the Xamarin Profiler is available. Changes since last release include:


  • Display heaviest stack trace in Call Tree’s stack trace view
  • Performance and stability improvements
  • Re-enable Time instrument for Android profiling


  • Use icons for right-side tabs
  • Change colors to match dark theme
  • Display timing information in Time instrument’s Call Tree view, not memory


  • Improve look of right-side tabs
  • Remember window size and position
  • Remember inspector area’s divider position

Bugs fixed:

  • 39412 - Scrolling problems in Call Tree view
  • 39810 - Scrolling problems in Stack Trace view
  • 39656 - Unable to start profiling with Trial license
  • 38300 - Missing keyboard support in template selector dialog
  • 40397 - Invalid license checks
  • 40598 - Drill down area not reset when restarting runs
  • 40600- Wrong scrolling when ‘Show in call tree'

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.
  • Time instrument not available for tvOS profiling
  • 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
  • Installation on Windows with previous versions (>= 0.24) fails, so old versions need to be uninstalled first

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