C# Class for Swagger.json

I need to parse a swagger.json file to dynamically find out what paths are available and what parameters for instance a POST requires. I do not know the content of it beforehand. Currently I am using the Newtonsoft JSON library to deserialize the swagger.json into a C# object. However, the parsing is kind of cumbersome. It would be so much easier if there was a known class that I can deserialize to. I understand that items like "parameters" will vary from case to case. Anyhow, is there a way to accomplish this? If not, what is the best way to parse a swagger.json file.
