I am looking to implement (or build as a last resort) a type of survey engine that allows for extensibility and integration into an existing workflow engine.
The survey/questionnaire engine should allow for admin users to add new questions and response types (text/bool/multiple/etc), should use SQL Server for persistence and ASP.NET 2.0 or greater. It should leverage AD for Windows Integrated Auth and security.
Does anyone know of a good (free or cheap is even better) off-the shelf solution that meets these basic requirements?
Try the C# open source Survey project (revived Nsurvey form engine and surveytool) at:
