Hi Wilfried,
ClikOnce works with file://, http:, https: protocols. Also, you don't need IIS, it should work fine with any web-server. The web-server you host the ClickOnce application must allow the MIME mappings discussed in this article.
http://msdn2.microsoft.com/library/ms165433(en-us,vs.80).aspxDoes this means that click once does not work on a reagularinternet site ? Note that most ISP doe not support HTTP uploads.
You can upload the deployment using FTP or any protocol your ISP supports. It does not have to be http. We support http: and file:// based publishing through VS2005. We don't support ftp. So if your ISP does not support http:// of file:// protocol for uploading you can alwasy use ftp:// to upload.
Thanks,
Sameer
