With your Workbench Bundle free trial download you will get every available feature from all editions for 14 days.
A free-forever license to use Task Factory in BIDS and SSDT (Visual Studio). Which means you can execute packages with Task Factory components within BIDS and SSDT (Visual Studio) forever without a license.
A 14 day full feature license to run packages containing Task Factory components outside of BIDS and SSDT (i.e. DTEXEC).
After the 14 day trial, you'll need a full license to run packages containing Task Factory components outside of Visual Studio.
