I have an issue with Swagger model preview. I using ASP.NET Web API.

It shows me this model:

But all model properties - is a private property names. So, on my opinion there must be Id instead of IdField, shortName instead of shortNameField.

Why does Swagger add Field suffix to the end of property name or using private field name as display name?
