API body parameter with Map/Dictionary Properties converting to object instead of Dictionary.
Response with Map/Dictionary Properties converting to Dictionary. we are expecting same behavior in parameters also.

Start with the supplied Swagger 2.0 declaration and the generated ResourceApi.cs signatures. Trace how the body parameter schema with additionalProperties is mapped for C# parameters, comparing it with the response mapping. Done means the generated parameter uses Dictionary<string, ResourceParameters> rather than Object, with the behavior covered by an appropriate generator test.
