Among the information that Microsoft deluged on developers at the BUILD conference are some details about its Roslyn project. Rosyln is an attempt to re-architect the C# and VB compilers to support “compiler as a service” (CaaS) scenarios.
At the conference, Microsoft Technical Fellow Anders Heilsberg revealed that the company plans to release a Community Technology Preview (CTP) of the Roslyn APIs later this month. He also showed off a version of Visual Studio that supported Roslyn. However, judging from the slides presented, it seems unlikely that Roslyn will be part of Visual Studio 2012.
