My problem started with an application that was just deployed. I’m getting an error when the application is closed. This only happens the first time after the initial run of the program where the Connection Wizard is used to configure the connection. After closing the error window I saw that the app was still alive in Task Manager and killed the process.   Re-running the app a second time without running the connection wizard allows the application to exit with no errors.

 

I went back to the development environment and created a simple app to see if happen there. Attached is screenshot of the error I received there.

All of this looks good.  Here is one question though, you mentioned you are using a shared settings file...does the same thing happen if you just manually enter the information in the Connection Wizard and do not use the shared settings file?  This could be the culprit as it does some stuff in memory and if it is coming from a network drive, I see this being a potential cause of the error since you are getting an exception.

Also, I am assuming that if you manually set the DataSources collection and circumvent the Connection Wizard, you do not get the error...correct?  Try taking the shared settings file out of the formula first, then we will go to hard-coding the path.  Let's get the error to go away and then we can start adding things back in.  Thanks.
