Roslyn analyzer, converted from C# to F#
I feel we can traverse the Roslyn AST but it's chatty and boring for write with a lot of non aspect code fragment :(

My suggestion for reference is my experimental project "F# Active pattern library for Roslyn Compiler Platform" can ease for use Roslyn AST directly F# pattern matching syntax.
