Auto mapping in ElasticSearch NEST client using underscore

Question

ElasticSearch recommends to use underscores for field names. I'm using Nest client and I have the following type:

public class Employee
{
    public string FirstName { get; set; }
    public string LastName { get; set; }
}

Nest client offers a feature called auto mapping that can automatically infer the correct mappings from the properties of the POCO. If use this feature I will get:

"employee": {
    "properties": {
        "firstName": {
            "fields": {
                "keyword": {
                    "type": "keyword",
                    "ignore_above": 256
                }
            },
            "type": "text"
        },
        "lastName": {
            "fields": {
                "keyword": {
                    "type": "keyword",
                    "ignore_above": 256
                }
            },
            "type": "text"
        },
    }
}

But fields does not conform naming convention. There is another feature for defining own mappings using attributes. But I don't want to specify it manually for each field. So is there a possibility to configure client to use underscores for combining words by default?

You can change the default field name inference of using camel casing to instead use snake casing through DefaultFieldNameInferrer(Func<string, string>) on ConnectionSettings
