Support Dictionary<string, string>

[Yavari]

Dictionary<string, string> generates following schema in .net core:

"schema": {
  "type": "object",
  "additionalProperties": {
    "type": "string"
  }
}

And Swagger shows Example Value as

{
  "additionalProp1": "string",
  "additionalProp2": "string",
  "additionalProp3": "string"
}

Can the pdf report show the same example instead of an empty response?
