I see 6 cases of "Microsoft .NET Framework" in my add/remove programs list, taking up about 600 MB of disk space (on 250 GB, that's less than 1%, practically nothing). The usage is showing "rarely" for all of these. This usage information is unreliable. I've used GIMP actively in the past 2 weeks and still shows up as "rarely" for both it and the related GTK. About 2 years ago, I didn't have any of this .NET Framework stuff. I'm only wondering what it's used for and if it can otherwise be uninstalled.
Edit: forgot the "uninstall" in subject line, for making it clearer.
