New Post: Silly Question... how do I know if it's working?

I've installed the plugin on VS2010, and went to the tools menu and configured it for my project.

Then I built my project. There was no message or anything to suggest that anything was different.

My program's ABOUT box grabs the value from:

System.Reflection.Assembly.GetExecutingAssembly().GetName().Version.ToString();

From what I'd read about the plugin, the string in ASSEMBLYINFO.CS where this comes from is supposed to be altered on each build. Yet, the ASSEMBLYINFO.CS file is unchanged and the string in the ABOUT box does not update.

So... how do I know if it's working? How do I get the updated version number at build time?
