Roslyn is a set of libraries for handling compilation, scripting, workspaces, and IDE services. It is an extensible model with VB and C# being the first two target languages. While still far from completion, Roslyn is targeting VB 12/C# 6, this release marks a major milestone for the project.
Microsoft's Channel 9 has released an interview with the principal developers of the Roslyn project. Karen Ng, Matt Warren, Peter Golde, Anders Hejlsberg provides some useful information on the project's goals and what the team is trying to accomplish.
Yesterday we talked about the Roslyn Compiler and Workspace APIs. Today we take a look at the Roslyn Service APIs and how they can be used to extend Visual Studio. The extensions we will look at today are Code Issue, Quick Fix, Code Refactoring, Completion Provider, and Outliner.
Early reports suggested that the Rosyln project would just be a better runtime-accessible compiler and REPL-style interpreter, but it turns out that it is much more ambitious. By opening up the entire compiler pipeline Microsoft hopes that developers will create a wide variety of tools at many levels.
