Solution 2

My suggestion may be more of a hack-solution than a good one, but I would possibly just open a handle to the file, thus marking it in use from the OS perspective, and not release the handle until the application exits. If you are trying to make the file undeletable in the OS at any time, even when your program is not running, I'm not sure it can be done.

Exactly. From the perspective of the OS, the file is "in use" as long as you have an active handle to the file in your application using the File.Open or something like that.
