The Computer Aided Systems Laboratory at University of Trieste, Italy has released on Feb 9, 2008 a Unit Operation Wizard for .NET to help developers realize CAPE-OPEN Unit Operations. The downloadable package contains both the Wizard and a Sample Unit developed with the Wizard.
While CO-LaN is not responsible for the use made of these software tools, CO-LaN encourages such developments that are simplifying the creation of CAPE-OPEN compliant components. Should you experience any difficulty or need further information on these tools, please contact Prof. Maurizio Fermeglia (maurizio.fermegli at dicamp.units.it).
Update (February 2020): use of the material in the distribution is reported in a Post on TechITMore.
