+About the CodeQL libraries for C#

-There is an extensive library for analyzing CodeQL databases extracted from C# projects. The classes in this library present the data from a database in an object-oriented form and provide abstractions and predicates to help you with common analysis tasks. The library is implemented as a set of QL modules, that is, files with the extension ``.qll``. The module ``csharp.qll`` imports all the core C# library modules, so you can include the complete library by beginning your query with:
