KeepPass2 is actually built on Mono, the open source multi-platform .net clone. It just happens to work with M$ .net.
I have it running on OS X, Linux, Android and Windows, all at the same time, while singing changed across platforms with secure Web Dav based cloud storage. Took me 20 min to set up on all four devices.
As someone who had their passwords leaked by an attack against one of the largest commercial password safes just a few years ago (heard of pwnedlist or the LastPass beaches?) I have been happily using KeePass as amuch more secure FOSS alternative with equal (if not more) functionality ever since, without any hangups to speak of.
