Summary

  • preserve the order of child tasks stored in a task continuation array when rendering dumpasync stacks
  • represent both tracked async objects and plain task continuations in the iterative depth-first traversal
  • add an end-to-end Task.WhenAll scenario that verifies first, second, and third continuations are displayed in registration order

Validation

  • Build.cmd
  • SOSAsyncTests.DumpAsyncContinuationOrder: 8 passed
  • baseline verification without the command change: 8 failed

Push continuation children in reverse stack order so they are displayed in the same order as the task continuation array. Add an end-to-end Task.WhenAll SOS test.
