I have been working in VS.NET 2003 since its inception. I have deployed both ASP.NET as well as Windows Forms apps to various servers innumerable times.Today I encountered a problem, which was indeed a dead end for me. When I was trying to build a Web Deployment Setup project, VS.NET threw me a Unrecoverable Build Error. Wow!
When I googled, I found many facing this issue. All of them pointed me to the Microsoft's support site article :http://support.microsoft.com/kb/329214/EN-US/
All I needed to do was to register the Mergemod.dll.
