We have recently developed a solution to install and run Rails applications on Microsoft IIS. Here is the link: Helicon Zoo - a repository of web frameworks and applications for Microsoft IIS. Currently IIS 7, 7.5 and IIS Express are supported. We expect to demonstrate production level performance in this environment on release. To use it you will need to install Web Platform Installer, as shown on the page, then click on "Blank Ruby on Rails Project" and after installation is completed overwrite this blank project with a real one or start development from this point.
Please help us to beta-test our solution. We need to collect some statistic on how real RoR application is operating in IIS environment. Please direct either success or fail reports to email@example.com or on Twitter using #heliconzoo hashtag: http://twitter.com/?status=%23heliconzoo
Thanks in advance!
