How can we assign the default value to an Out Argument in a workflow?

Why is assigning default value to an Out argument not allowed in a workflow? I see it is allowed for an In argument, but only blocked for an Out. Will I have to assign the Out Argument in an Assign activity inside a workflow? Any other alternatives?

That’s a Workflow Foundation (MSFT) limitation.
However, just use assign arg = value at the start of your workflow.

Can you please elaborate on this. I am having the same issue what Amrita had!

It’s not allowing to put a value for an Out-Argument! really confusing!
