"Oslo" is the code name for Microsoft’s platform for model-driven applications. The goal of Oslo is to provide a 10x productivity gain by making model-driven applications mainstream with domain-specific models, a new language, and tools.
To support developers using Oslo, MSDN has launched the new Oslo developer center featuring the Oslo SDK, videos, and great Oslo blogs from people like Chris Sells, Don Box, Aaron Skonnard, and others…
…and a new MSDN Forum.
For the very latest on Oslo, see this PDC2008 session video on Channel 9, or visit the PDC2008 event site.
