Tips:Deploying a Custom Add-In Task
You can add Custom Tasks to SAS® Enterprise Guide and the SAS® Add-in for Microsoft Office in order to provide a custom user interface. SAS® Enterprise Guide 4.1 tasks must be written using .NET Framework 1.1 (or earlier). SAS® Add-in for Microsoft Office 2.1 tasks can use later releases, including the current release: .NET Framework 3.5.
