Does anyone know the .net library for winforms to perform the same function for my applications as the "Report a bug" link in a gmail application?
Screenshot with highlight / dimming function seems very useful.
This is not freeware, but redgate has a library called SmartAssembly that supports error reporting out of the box.
You can use the NBug library, although so far it does not have "feedback on request" (only s> v1. 1). He is currently reporting all exceptions.
There is also a Google Breakpad for handling SEH exceptions, but this is in native code.
