I have an application that zips up some files and then attempts to send that in an e-mail as an attachment.
I have noticed that if the zip file is small it works fine (A few KB's), but the zip is generally between 1 and 2 MB's, and at that size (Which is still rather small) it fails. I get an error that it failed due to the target of an invocation.
I'm assuming that perhaps the zip file is not being released prior to the e-mail being generated when it's larger? I have both the zip creation and e-mail generation in their own backGroundWorkers.
I've been working on this for a good while now, and it doesn't seem to matter if my AntiVirus is running (I thought maybe it was trying to scan the zip), if I do a thread.Sleep, if I choose to send the mail upon the click of another button, etc. In fact, curiously, I created a test application that ONLY sends the zip file. This works perfectly. However, if I use my main application to create the zip file, this test application will be unable to send the zip until after the main application is closed. I really think that the file is not being released, but I don't know why, or from what. The backgroundWorker that is creating the zip is completing successfully (That is where I was originally calling the SendMail event).
My question is what the suggested course of action would be for doing something like this. I've never had an issue with accessing a file like this before.
I really appreciate any suggestions anyone may have for this. I can post whatever code you want, but there's a lot of it, so I'm not sure what all you would want.

Hello everyone.
