I was trying to resolve a reference in a project that could not be found. Microsoft.Web.Services. I went to get the latest and greatest WSE from Microsoft and download it. After I installed it, I still had the reference problem. It ended up being a reference to WSE 1.0. After getting the WSE 1.0 install, no problem.
This is a perfect example, IMHO, of not thinking about usability. Should the WSE 2.0 download have included the 1.0 bits? Your thoughts?
