After upgrading application from VS2010 RC to VS2010 RTM, my application stop working. I started to receive the error below, when I try to run/debug my application.
“ArgumentNullException was unhandled“
Value cannot be null.
Parameter name: activationContext
After doing some research online. I have found the solution.
- Go to your project properties [Double click on “My Project“].
- Click on the “Security” tab
- Un-tick the check-box for “Enable ClickOnce security settings“
Then try to run your application again. It should work fine.
Hope you find it useful.
