What are the maximum number of a processes the "Parallel Activity" could contain?



If i use a ParallelActivity in my process, i want to know what are the maximum number of processes/activities “ParallelActivity” could contain? Is there any such limitation?


Hi Jyoti,

In theory there is no limitation. But it depends on which activities are you trying to run in parallel and if they run exactly in the same time it can crash, especially uiautomation.

For example, there was a known issue that we don’t support two parallel Get text activities.

Details about parallel class here: https://msdn.microsoft.com/en-us/library/system.activities.statements.parallel(v=vs.110).aspx


The BOt will also give undesired result in “Copying Clipboard” option


Thanks. :slight_smile:


Is there a plan to address this limitation or maybe implementing a lock activity so you could get exclusive access to these activities(Get text and other) ?

Is there a list of activities that are supported inside parallel activity?
