I'm pleased to announce that we have released a beta version of the FPSE extensions for IIS7. You can download the beta release from IIS.NET's DownloadCenter here: http://www.iis.net/downloads/default.aspx?tabid=34&g=6&i=1460.
Read more about how to install and use them in this article. Join the Publishing Forum on IIS.NET forums for questions and answers related to FPSE on IIS7.
We partnered together with Ready-to-Run Software to update the FPSE extensions to enable them to work with IIS7 on Windows Vista as well as the latest Longhorn Server Beta 3 release. Many thanks to Robert McMurray on the IIS team for driving this project and making it happen!
