25.8.0August, 2025
.Net Agent
  • Includes code enhancements and bug fixes. See Agent Resolved Issues.

  • The agent now delivers refactored asynchronous business transaction tracking with an improved waterfall view for snapshots. The following new behaviors are introduced:

    • The waterfall view presents asynchronous segments without connecting lines between them.
    • Nested POCO Service Endpoints are no longer supported.
    • Errors on asynchronous end segments are now reported directly on those segments, instead of being reported at the business transaction top level within the instrumented process. Error propagation to the top level remains available via the node propertyenable-all-rsd-error-propagation.
    • The node propertytrack-all-asyncis deprecated. Asynchronous visibility beyond the previous default of five nested asynchronous executions is now enabled by default, making configuration of this property unnecessary.
