Oslo SDK CTP
At the end of last week a new CTP release of Oslo was made available for download. Oslo is an application development platform that uses domain models, languages, and tools to improve the productivity of application design. At one time Oslo was very tightly coupled to certain development technologies such as WCF and WF. Over time though Oslo has had some additional decoupling from specific messaging or workflow approaches and has had a broadening of applicable domains.
Here are a few other resources associated with the release:
