Microsoft is making strong efforts to ensure interoperability in various technology fronts, including building runtime environment for non-Microsoft development languages on Windows platform. Ruby runtime implementation on .NET Framework, and Ruby implementation on the latest Microsoft cloud platform technology, Windows Azure, are some examples of achievements. More than ever before, Microsoft is more open with our technologies and more open to Open Source technologies. And we‘re open to choice and change. Because openness helps us all move up. Microsoft is looking forward to working together with Open Source communities closely and worldwide.
