Set custom type name in mapping

I need to create a document mapping that has a custom name. Currently I have the following mapping for my document on the CreateIndexDescriptor object:

.Mappings(m => m
  .Map<MyDocType>(mDetails => mDetails.AutoMap()));

Which creates a document mapping called mydoctype. How can I modify this so it creates a document whose type name is my_doctype?

In NEST 7.x, this is not possible - the document type will be _doc, in line with the roadmap for the removal of mapping types.

In NEST 6.x, you can specify the type name to use in a few different ways:

  1. Using ElasticsearchTypeAttribute on the POCO

    [ElasticsearchType(Name = "my_doctype")]
public class MyDocType{ }

  2. Using DataContractAttribute on the POCO

    [DataContract(Name = "my_doctype")]
public class MyDocType{ }

  3. Using .DefaultMappingFor<T>() on ConnectionSettings

    var settings = new ConnectionSettings()
    .DefaultMappingFor<MyDocType>(m => m
        .IndexName("my_doc_type_default_index")
        .TypeName("my_doctype")
    );

var client = new ElasticClient(settings);
