Publish to Azure in VS

[lbcsy]

I can publish Orchard to Azure App Service in VS and get it up and running with no difficulty at all, but then I don't know how to modify folder's (i.e., Modules, Themes etc.) permission so that installing modules and themes will not complain "~/Module" or "~/Themes" is not writable:

Package installation failed: There was an error installing the requested package. This can happen if the server does not have write access to the '~/Modules' or '~/Themes' folder of the web site. If the site is running in shared hosted environement, adding write access to these folders sometimes needs to be done manually through the Hoster control panel. Once Themes and Modules have been installed, it is recommended to remove write access to these folders.
