VSTO Add-In Loading Twice Paulem0071 11/12/2008 8:08:02 PM All, I have posted here before and received great advice. However, I am writing a VSTO Outlook Add-In, and still have an issue where the Add-In loads twice When debugging and sometimes starting Outlook 2007. I have tried Mutex, registry checking and a variety of other methods to no avail. Any suggestions? My goal is to ensure only one copy of my Add-In loads and executes. I have confired the Add-In is loading twice as "ThisAddIn_Startup" is fired two times. Thank you.
