First of all -- very good product!
I had some issues to make it to work and I'd like to share my experience.
First, I installed BuildVersionIncrement v2.0 for VS2008. It created the menu item under Tools and I was able to configure the add-in but it didn't work. No error messages, no version change. Then I tried several versions of the add-in
from the past and got to the point where add-in reported the following error: "method not found EnvDTE80.ErrorList"
It appeared that I had 2 different versions of EnvDTE80.dll in the GAC. The older version (8.0.50727.932) that was probably left behind by VS2005 beta didn't have all necessary methods. I got rid of that dll and everything started to work
with the new one. Unfortunatelly, version 2.0 of the add-in doesn't report that error. No matter, it works now and I'm pretty happy with that.
