Hi

I want to upgrade my solutions to 8.1. But everytime I let the upgrade run,
I got a " Object reference not set to an instance of an object.". I try the
addin the commandline version and the winforms application. Everytime the
same result. The solution contains over 175 projects. I am not willing to
upgrade every project by hand. So want can I do?

I have a subscription including the source code. Where can I find the
sourcecode of the upgradeutility? I would like to fix this very annoying
bug.

Bye
Michael
