Compiler as a service

Microsoft has been working on how some parts of the source code of the compiler can be opened up to the world. Consequently, as a programmer, you are capable of querying the compiler on some of its internal work principles. C# 6.0 introduced a number of libraries that enable the developer to get an insight into the compiler, the binder, the syntax tree of the program, and so on. Although the features were developed for a long time as the Roslyn project, Microsoft have finally released it to the external world.
