I have a issue with an invoked workflow. This one have two arguments, one as “In” another as “Out” and my problem is with this last.
This argument is typed as “ICollection” as I show below:
When I try to add a string to this collection using the “Add to Collection” activity and run this project I receive this error: “The property ‘Collection’ of ‘Add to collection’ is not initialized”
Okay I know, this error can be solved initializing an variable as new List(Of String) but it can’t be done when is a out argument.
