Do you have an automated build system in place for your development? This morning I came in, ran my NAnt script which cleaned my Build directory out, built every project within my solution, copied over the .exe's, .dll's, .config's, .xml's and .manifest files, then it subsequently invoked my WiX script that built a complete MSI installer package, including the web service deployment. Wow, all this and I haven't even had my coffee for the day.
