I have considered moving to the Web Application Project
setup that came out. HAve you had experience with this
setup (like the old 2003 format) ?
Even tho I have nothing in my App_Code directory, I too
have noticed it takes a long time to do the builds.
Web Application Project takes significantly less time to
build. The main reason for this is time that takes VS to
generate Webform designer classes (partial classes with
controls definitions and initialization) in case of Web
Site. In case of Web Application Project those files
pre-generated at design time and saved to file system.
Use WAP to optimize speed up your development process if
you willing to let go to some flexibility.
