Ignore base class properties during auto mapping in ElasticSearch using NEST

[nkdev89]

I'm working on Elastic Search 5.4 and using NEST to create index in C#, When i do a automap for a class which in Inheriting from SortedDictionary, The base class properites like Count,Comparer,Items are added to the Mapping, Can some one please help me how to avoid this.

Thanks

 public class Document : SortedDictionary<string, dynamic>
 {
    public int Id { get; set; }
 }

The actual mapping I'm getting is

{"DocumentMapping": {
"mappings": {
  "Document": {
    "dynamic": "strict",
    "_all": {
      "enabled": false
    },
    "properties": null,
    "Documents": {
      "properties": {
        "Comparer": {
          "type": "object"
        },
        "Count": {
          "type": "integer"
        },
        "Item": {
          "type": "object",
          "include_in_all": false
        },
        "ID": {
          "type": "int "
        }
      }
    }
  }
}}}

What i need is

{"DocumentMapping": {
"mappings": {
  "Document": {
    "dynamic": "strict",
    "_all": {
      "enabled": false
    },
    "properties": null,
    "Documents": {
      "properties": 
        "ID": {
          "type": "int "
        }
      }
    }
  }
}}}

How do i ignore the the Comparer,Count and Item from my mapping JSON.

I initially started a reply saying you can totally do this using the visitor that you can supply to AutoMap() then proceeding to draft an example I was shocked. "no you can't!"

I've opened #3001 which will make this possible in the next 5.x and 6.x releases.
