If you don't know what is it, you cannot possibly "want" it.
The question makes no sense at all. "Write protection" means protecting something from being modified. Everything else depends on: what do you want to protect and why? Don't even bother answering...

Doesn't matter; the user's wants always outweigh the developer's wants.

Write protection is a (software based) way to prevent writes to a file, or folder. (USB sticks and memory cards are different, the write protect on those is normally hardware based and requires a physical change to enable or disable.) Your setup program can set a folder to read only - it's in the File class:

C#

File.SetAttributes(folderPath, FileAttributes.ReadOnly);

But...if your program is being installed properly anyway, modern OS's won't let anyone write to the "ProgramFiles" folder or subfolders without Admin access (and an Admin can remove ReadOnly from a folder anyway).

So probably the best thing to do is just let your setup program put the app in the "normal" place, and just create a folder below the app to store your read-only data. Then there is nothing else you should really need to do.
