ChocolateyLibDirHelper.VersionChangeFinished Index OOR Exception

Loaded the application (in debug) with no saved settings. Went to menu and configured my settings folder. Clicked the "Installed Applications" tab and the load bar start going at bottom. Received an IndexOutOfRangeException:

System.IndexOutOfRangeException was unhandled
  HResult=-2146233080
  Message=Index was outside the bounds of the array.

Ok, maybe this happens independant of me setting that file. The application now starts with the Installed Packages tab selected and immediately gets that exception.

Since the application couldn't find chocolatey, it was getting unexpected output from powershell. I changed the logic to explicitly throw a ChocolateyVersionUnknownException in this situation, but I'm not sure how we want to handle the logic higher up in the interface. Thoughts?

Show a messagebox that say "Chocolatey can not be found do you wan tot install it?" On Yes install it with the little powershell script. On No just quit the application. But this should be rare since chocolateygui is supposed to be installed from chocolatey.

[tarwn]

Awesome, no idea how to do that. I'm unfamiliar with the way the application is interacting (using events for continuation) and I haven't done a windows app in years, so I may need someone to step in and do that last bit :)

Code review? I added delegates for the Failed run, but switched from a Thread to using TPL (Task.Factory.StartNew) and lambdas to start and then handle faulted calls. I'm still trying to discover the root issue, which is why my chocolatey install isn't returning the expected version output :)

[chrissie1]

can I close this?

[tarwn]

No, because I did, so there :)
