Deep cloning objects from Autorest generated code

Question

I am using Autorest to generate code to call my api.

I want to use the following in my unit tests

    private JobHeaderRequestObject MakeRequestFromResponse(JobHeaderResponseObject InResponseObject)
{
    // make use of the fact that in the server side code we know  JobHeaderResponseObject inherits from JobHeaderRequestObject 
    return MySerializer.DeepConvert<JobHeaderResponseObject,JobHeaderRequestObject>(InResponseObject);
}


internal class MySerializer
{

    public static T2 DeepConvert<T1,T2>(T1 obj)
    {
        using (var ms = new MemoryStream())
        {
            var formatter = new BinaryFormatter();
            formatter.Serialize(ms, obj);
            ms.Position = 0;
            return (T2)formatter.Deserialize(ms);
        }
    }
}

However when I try to run this code I get an error mentioning

System.Runtime.Serialization.SerializationException   

indicating that the type

is not marked as serializable

I don't want to go through the generated code adding the attribute

[Serializable]

to each type, because the code will get overwritten the next time I generate.

I looked at this issue on the Git Hub project and it mentions

If the swagger spec has a model definition like this

{
  "Foo": {
    "properties": {
      "name": {
        "type": "string"
      },
      "age": {
        "type": "number"
      }
    },
    "additionalProperties": {
      "type": "string"
    }
  }
}

then Autorest generated SDKs should be able to serialize and deserialize (round trip) the unknown properties correctly.

Generated C# clients support this today by having a Dictionary AdditionalProperties.

So now I am trying to understand what an Autorest spec is and how I set it up.

In startup.cs I have in Configure

            app.UseSwagger(c =>
        {
            c.RouteTemplate =
                "api-docs/{documentName}/swagger.json";
        });



        app.UseSwaggerUI(c =>
        {
            //Include virtual directory if site is configured so
            c.RoutePrefix = "api-docs";
            c.SwaggerEndpoint("./v1/swagger.json", "Api v1");

        });

In ConfigureServices I have

        services.AddSwaggerGen(c =>
        {
            c.OperationFilter<AuthorizationHeaderParameterOperationFilter>();
            c.SwaggerDoc("v1", new Info
            {
                Version = "v1",
                Title = "My API",
                Description = "ASP.NET Core Web API",
                TermsOfService = "None",
                Contact = new Swashbuckle.AspNetCore.Swagger.Contact
                {
                    Name = "MyName",
                    Email = "MyEmail@Mydomain.com"
                }


            });

            c.EnableAnnotations();
            c.DescribeAllEnumsAsStrings();
            c.ParameterFilter<SwaggerEnumParameterFilter>();
            c.SchemaFilter<SwaggerEnumFilter>();
        });
