Accessing data in console application run as scheduled task

Question

Hi,

 

My requirement is to send a mail whenever the status of a set of employees change from "Active ->Inactive" / "Inactive->Active" .

 

I have implemented as a console application which is configured in the windows task scheduler to run every 5 mins. This app calls the web service, checks the status and sends mail. But I need the previous execution employee list in order to check if any change in status has occurred or not with the currently retrieved status. I believe static variables won't be of any use as the application is run during each 5 mints. Please advice.

 

Thanks,

Divya
