Examples are missing after converting V3 swagger to V2

[TinaLiu02]

Bug:
we need to convert V3 swagger to V2 and transform the examples, but examples part in request/responses/components are missing after converting V3 swagger to V2.
v3 swagger file: https://github.com/linkedin-developers/job-posting-development-tools/blob/master/OpenAPI-specification/job_posting_v2.yaml

To Reproduce
Steps to reproduce the current behavior:

1. run project Microsoft.OpenApi.Workbench
2. copy the content of v3 swagger file and paste it to "input content" area
3. choose JSON for Format, choose V2.0 for Version and click button "Convert"

Expected behavior
examples should display in V2 swagger.

Unfortunately there is no support for multiple examples for body parameters in OpenAPI v2. We could carry the examples though to the V2 document as an extension. e.g. x-examples Would that address your need?

[TinaLiu02]

yes. that would be great.

[darrelmiller]

We need to add serializing of the examples map to x-examples here

OpenAPI.NET/src/Microsoft.OpenApi/Models/OpenApiResponse.cs

Line 187 in 05c5615

if (Content.Values.Any(m => m.Example != null))

@MaggieKimani1 Why is this a breaking change? Could this not be implemented in the current V1.x branch?

You're right, this isn't a breaking change. I have rebased the branch onto vnext so that this goes out with the next v1.x release.
