w3wp.exe keeping files locked after processing in webservice

Question

I have a webservice and I noted that some dlls in the wwwroot folder are kept logged after the webservice is executed.

After restart of pc, the problem is solved.

Can i have something in my code that releases the dlls?

Answer 1

Try to either recycle the AppPool which your webservices runs under, or use iisreset.

iisreset /stop will stop IIS and release the dll's. iisreset /start will start IIS back up again.

If you recycle the Application Pool, then the lock of dll's will be released until someone hits your webservice again, and aquires a new lock.
