Excel does not leave memory

[John Bailo]

I wrote a c# web service that creates an Excel spreadsheet. Even
though I follow all the formal procedures for closing the app and
finalizing, an instance of Excel still remains in memory. Is this a
problem? With that instance of Excel.exe eventually go away because of GC?

I follow the procedures described here:

I converted this app to a console app, and in this case Excel.exe does
leave the task list.

But when run as a web method, Excel.exe stays there with IUSR_ as the owner.

I'm trying to get rid of this instance once the method ends.
