I am developing an application in WPF / .Net 3.5 that will be available for download on the internet. I am - to the best of my ability - writing bug free code, and using exceptions only where necessary. However my experience with software development has shown that users always manage to do something strange which causes an exception to be thrown in a way you could never imagined possible. I would like to gather additional information when I have to catch an unhandled exception. So far I am capturing the following:
- Standard Exception fields (message, type, stacktrace etc)
- OS Version
- .Net version
- Versions of the Applications DLLs loaded into the AppDomain
- App licence information
- Instrumentation of the last few commands executed by the user.
I am very concious that I do not want to capture any 'personal' information about the user as I just don't believe in that sort of thing. Hence not bothering with the username/domain/ip address (although as the exception information is delivered to a webservice I will inherently get ip information but it may be of a proxy machine).
My Question
Anyone who has released an application into the public domain (i.e. onto computers not in a controlled corporate environment) - can you suggest anything else that would be useful in tracking down the causes of errors?
Particularly I do not want to collect information that I cannot manage/code for - I.e. the amount of memory available on the PC, or type of printers attached - These things are handled by the .net framework and I shouldn't really (read: don't want to) have to alter my code to cope with the variations out there!
Thanks!
