Microsoft has released Microsoft WebDAV Extension for IIS 7.0 (

The Microsoft WebDAV Extension for IIS 7.0 helps you enable powerful publishing capabilities for your Web environment.

Integration with IIS 7.0: IIS 7.0 has a brand-new administration interface and configuration store, and the new WebDAV extension module is tightly integrated with this new design. The old IIS 6.0 metabase is gone, and a new configuration store that is based on the .NET XML-based *.config format has taken its place. In addition, IIS 7.0 has a new administration tool, and the new WebDAV extension module plugs seamlessly into that paradigm.
Per-site Configuration: WebDAV in IIS 7.0 can be enabled at the site-level, unlike IIS 6.0 which enabled WebDAV at the server-level through a Web Service Extension.

Per-URL Security Settings: The new WebDAV extension module supports per-URL authoring rules, allowing administrators to specify custom WebDAV security settings on a per-URL basis. These authoring rules are separate from the IIS 7.0 per-URL authorization rules, thereby allowing one set of security settings for normal HTTP requests and a separate set of security settings for WebDAV authoring.
