Profiler Preview 0.9-0

This is the initial preview release of the Xamarin Profiler. The features include:

  • Support for launching and profiling iOS (Mac only) and Android applications (Windows & Mac)
  • Two instruments - Allocations & Time Profiler
  • Summary of allocations with option to see callers and backtrace, as well as sorting and search on Mac
  • Call tree for drilling down, with options to separate by thread and invert (supported on Mac only)
  • Samples list and call tree for Time Profiler/performance.
  • Generations to take and review memory snapshots (supported on Mac only)
  • Allocations list with addresses/size/caller info on all allocated objects.
  • Support for lightweight integration with Xamarin Studio on Mac and Windows and Visual Studio
  • Support for profiling most build configs on Android and Debug build configuration in iOS.
  • Support for Android devices and emulators, including Xamarin Android Player.
  • Support for iOS Simulator.


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

  • Profiling Mac apps is not yet available.
  • Limited support for iOS device profiling.
  • No official support for profiling Release builds
  • Snapshots, call tree sorting not implemented on Windows
  • Can't search call tree on Mac or Windows
  • Data sets are correct at time of collection but data mining and representation is preliminary. This will improve in future releases.
  • Chart drawing is somewhat unstable, especially for allocations
  • No support for comparing/seeing delta of snapshots in this version
  • Samples list not available on Android
  • Live/Dead object status not yet supported - profiler always shows live

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