NUnit [TearDown] fails — what process is accessing my files?

Question

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:

Answer 1

Do you have Antivirus running? Some AV products scan the file when they see them being closed. If the AV software still has the file open when you come to delete it, you'll see this problem. You could retry the delete after a small delay.

I've also seen this happen with search indexers.
