WSIT is delivered as part of the Metro Web Services Stack. Please go to the Metro site for downloads, documentation, etc. Here you find "Overview" (PDF) and another Shorter overview article.

All of Metro (including WSIT) is tested for interoperability between the Java platform and Windows Communication Foundation (WCF) (aka Indigo) in .NET 3.0 and .NET 3.5. (Listen to what Microsoft has to say about interop with Project Tango in this Server Side interview.)
