After seeing the Hanselman "You are doing it wrong" video I start to use the Web Publish feature of VS2010.
What I'm really missing is that the websites sometimes gives errors while the site is publishing because the feature does not copy the app_offline.htm file to the server.
I do not want to start using MSDeploy scripts, because I have several sites and want to keep it simple.
Maybe there is a simple tweak to tell the wizard to copy and then delete the file.
