OpenApiResponseWithBody - Does not handle classes with IImmutableList

[torepaulsson]

Hi,
This is really a great extension, just tried it out and will use it on all the azure functions we have! I noticed that there was a problem rendering the response body of a class when it has a property type of IImmutableList. I tried changing to IList and that works fine.

public class ResponseDto{
   public ImmutableList<some class> List {get;}
}

renders just an empty class like so:

{
   "list": {}
}

It would be great to add support for IImmutableList!

@torepaulsson I hope this PR #247 sorts out your issue. Please wait for the 0.9.0-preview release!

That was very quick, thank you!
