I have compiled JS Builder v.1.1.2 under Linux (Ubuntu 7.04) with the latest mono packages.
I haven’t really tested it but someone can be interested in trying it anyway. You can download the binaries and the sources from here.
This version of JS Builder does not compile right away with mono. There are few issues to take care of.
The XmlSerializer crashes the application. I have replaced it with the SoapFormatter.
JS Builder writes to the registry to register an extensions. I have excluded this operation under Linux.
There are a few methods that on mono fail, so I have corrected these as well.
I have also replaced hard coded backslashes in paths with System.IO.Path.DirectorySeparatorChar.
