Excel not shutting down properly

[Stephen]

I have an office addin which runs for Word, Excel and Powerpoint. The
problem I am finding is that when I run Excel and then quit, the Excel UI
closes but EXCEL.EXE remains in the task list. This does not happen when
using Word or Powerpoint.

I checked that my addin has finished, including the worker thread which I
have running, and so don't see why it should still be running. I thought it
might be something to do with a object hanging around somewhere so I set all
object back to null and forced garbage collection but still no joy.

Could someone help please.

I've traced this problem down to the fact I'm accessing (Excel)
application.Workbooks on a separate thread. The same calls work fine if made
from the main thread.

Is this not allow or is there something else I need to dispose of after
making this call?

thanks, now use System.Runtime.InteropService.Marshal.ReleaseComObject,
works a treat!

Cheers,

I get this situation when using a web service inside
a .NET add-in in Excel ..


Do you think it is the same issue ? Holding on to a RCW
refreence??
