Final Edit: I found a solution to the problem (at the bottom of the question).
I\'ve got an Nunit problem that\'s causing me grief. Edit:
Thanks for pointing this out!
The problem is not related to SQLite, but rather to memory management in general. After your test has run, the objects pointing to files have no scope anymore, but they still exist in memory.
Hence, there's still references to the files and you can't delete / move them.
