Memory profiling

  • feature New action Exclude Retained Objects opens a new tab with all the objects from the current set except for the retained set of the current selection. You can find the action in the popup menus of memory views.

    Ignoring retained objects and focusing on the rest might help finding memory leaks and analyze memory distribution.

    Exclude retained objects popup
  • fix Action Memory | Contained Objects might not show elements of System.Collections.Concurrent.ConcurrentQueue.


  • improvement .NET Framework is no longer required to install and use the profiler.

  • improvement New activation wizard improves UX of profiler activation and evaluation. Wizard guides through the activation and gracefully handles corner cases when the computer has no Internet connection, behind a proxy, etc.

    Activation wizard
  • improvement Due to security reasons the startup option listen has been reworked and accepts now the following values:

    • Most security: The default option: listen=localhost opens the profiler agent socket on the loopback network interface. Previous default was listen=all.
    • Easy access: listen=all opens the profiler agent socket on all network interfaces.
    • Advanced: listen=<IP or host> opens the profiler agent socket on the loopback interface and on the specified IP address.
  • fix In SSH configuration it was impossible to choose private SSH key from the hidden directory.
  • improvement Bug fixes and performance improvements.
