When .NET first burst on the scene, we talked a lot about “XCopy deployment”. What we meant was that you didn’t need registry entries, you didn’t need to copy DLLs to windows\system32 or whatever, you didn’t need to mess around with the person’s computer hardly at all – you just copied the exe and dlls into some folder somewhere, optionally a foo.exe.config into the same folder, and you were good to go. But we really should have called it “FTP deployment” because people would come up to me at the end of talks and ask where to find the XCopy utility that you needed to deploy .NET applications. Ooops.
For those who never knew it, XCopy was a command (extended copy, a replacement for the original copy) that came with DOS. It was so much better than copy because, among other things, if the target floppy drive was full when you were copying a whole pile of files, it would prompt you to put in another one and keep going, where ordinary copy would go “disk full” and abandon the whole thing.
I admit, it’s been well over a decade since that’s been an issue, so it perhaps was no surprise to read that XCopy has gone the way of all utilities ... replaced by something shinier that has less compatibility issues with the new operating system. Of course it isn’t exactly gone, just deprecated. OK. I might have to learn Robocopy now. But I promise never to speak of Robocopy deployment. That just sounds weird.
