@dotnet-policy-service agree

It makes sense. Only thing I'm unsure of is whether we should reuse the BreakSignal, or if it would be better to create a dedicated EndSignal. The former is intended to break out of a "scope" such as a for-each activity's Body, while the latter would be intended to complete the closest flowchart activity containing the End activity.

Thoughts?

[iio888]

Good idea! The EndSignal is better than BreakSignal exactly.
I’ll modify my code. Thanks for your advice

Now the End Activity will ends all the parent flowcharts. Is it will be better that just ends the last flowchart and stop propagation? @sfmskywalker

[sfmskywalker]

Yes, the End activity should only end the current Flowchart and not all of its ancestors. This is in contrast to the Finish activity, which is intended to finish the workflow from anywhere in the graph.
