Roslyn is an open source platform, developed by Microsoft, containing compilers and tools for parsing and analysis of code written in C# and Visual Basic.
Roslyn is used in the Microsoft Visual Studio 2015 environment. Various innovations such as code fixes are implemented by means of the Roslyn platform.
Using the analysis tools provided by Roslyn, you can do a complete code parsing, analyzing all the supported language constructs.
The article can be divided into 2 logical parts:
- General information about Roslyn. An overview of tools provided by Roslyn for parsing and analyzing the code. We provide a description of entities and interfaces, as well as the point of view of a static analyzer developer.
- Peculiarities that should be taken into account during the development of static analyzers. Description of how to use Roslyn to develop products of this class; what should be considered when developing diagnostic rules; how to write them; an example of a diagnostic.
