I have a Visual Studio 2012 web project that I am publishing to a Windows Server 2008 R2 server. I was having issues with the updates I was making locally not working on the remote server. When I checked the "Delete all existing files prior to publish" it successfully deleted the files from the server but then didn't add the new files - and yet claimed (in VS2012) that the publishing had been successful.
If I copy the PackageTmp folder up into the directory on the server manually, then everything works fine. Why is VS 2012 thinking it is copying but isn't really?
