I am using Windows Azure, and find it a lot difficult and useless make a new "Package" each time you make a small change, and want to test it on the Cloud. I heard about the opportunity to update the web roles without re-deploy the whole instance each time (about 15 minutes), and do a Web Deploy - upload just the modified files (some seconds).
None of the resources found on the web seems to describe this particular situation.
There are tutorials, on how to enable Web Deploy on Azure Web Roles, but not a one how to set it up. [This tutorial is showing the settings, but not for Azure]


Here the things go little hard, if you have not messed with Web Deployment before.
