How to create code analyzer tool/plugin/addin to verify MVVM

Question

 
I want to create plugin/tool/addin to verify wether the code has implemented MVVM pattern and to show the code which violates the MVVM pattern rules in .net code.
I dont want to use any paid plugins or tools so i decided to create my own.

So, I also want to know wether it is possible to develop such type of pulgin/macro in visual studio. And if yes then how.


So i am very thankful if someone guide me in creating this plugin. I want to use C#.Net language.
