Add-ins allow you to extend the functionality of the PowerBuilder .NET environment.
Add-ins can be written in any .NET language, including PowerBuilder .NET, and must follow Microsoft Visual Studio 2008 guidelines. The configuration file for each add-in must include PowerBuilder .NET as an allowed host.
<HostApplication> <Name>PowerBuilder .NET</Name> <Version>12.0</Version> </HostApplication>
For information about creating add-ins, see http://msdn.microsoft.com/en-us/library/5abkeks7.aspx and http://www.c-sharpcorner.com/UploadFile/mgold/AddIns11292005015631AM/AddIns.aspx. Microsoft help for enabling add-ins in an isolated shell environment is available from the Add-in/Macros Security page under the Environment node of the PowerBuilder .NET Options dialog box.
