NEST 1.0 - What is the new .MapFromAttributes()?

I have some POCOs that’re decorated with attributes. Inside they look like this:

[Serializable]
[ElasticType(DisableAllField = true, IdProperty = ElasticsearchFields.FullUncPath)]
public class ShareDriveDocument
{
    [ElasticProperty(Name = ElasticsearchFields.Id, Type = FieldType.string_type, Store = true, Index = FieldIndexOption.not_analyzed)]
    public string Id { get; internal set; }

    [ElasticProperty(Name = ElasticsearchFields.FullUncPath, Type = FieldType.string_type, Store = true, Index = FieldIndexOption.not_analyzed)]
    public string FullUncPath { get; internal set; }

    [ElasticProperty(Name = ElasticsearchFields.FileName, Type = FieldType.string_type, Store = true, Index = FieldIndexOption.not_analyzed)]
    public string FileName { get; internal set; }

    [ElasticProperty(Name = ElasticsearchFields.ParentDirectory, Type = FieldType.string_type, Store = true, Index = FieldIndexOption.not_analyzed)]
    public string ParentDirectory { get; internal set; }

    [ElasticProperty(Name = ElasticsearchFields.DateCreated, Type = FieldType.date_type, Store = true, DateFormat = ElasticsearchDateFormats.NoMillis)]
    public DateTime DateCreated { get; internal set; }

    [ElasticProperty(Name = ElasticsearchFields.DateModified, Type = FieldType.date_type, Store = true, DateFormat = ElasticsearchDateFormats.NoMillis)]
    public DateTime DateModified { get; internal set; }

    [ElasticProperty(Name = ElasticsearchFields.SemanticFulltext, Type = FieldType.string_type, Store = true, IndexAnalyzer = "english")]
    public string SemanticFulltext { get; internal set; }

    [ElasticProperty(Name = ElasticsearchFields.ExactFulltext, Type = FieldType.string_type, Store = true, IndexAnalyzer = "not_analyzed")]
    public string ExactFulltext { get; internal set; }

    [ElasticProperty(Name = ElasticsearchFields.OriginalSize, Type = FieldType.long_type, Store = true)]
    public long OriginalFileSize { get; internal set; }

    [ElasticProperty(Name = ElasticsearchFields.TextSize, Type = FieldType.long_type, Store = true)]
    public long TextContentSize { get; internal set; }

    public ShareDriveDocument(IndexingJob indexingJob, string fulltext)
    {
        var fileInfo = new FileInfo(indexingJob.PathName);

        FullUncPath = indexingJob.PathName;
        FileName = Path.GetFileName(indexingJob.PathName);
        ParentDirectory = Path.GetDirectoryName(indexingJob.PathName);
        DateModified = fileInfo.LastWriteTimeUtc;
        DateCreated = fileInfo.CreationTimeUtc;
        SemanticFulltext = fulltext;
        ExactFulltext = fulltext;
        OriginalFileSize = fileInfo.Length;
        TextContentSize = fulltext.Length;
    }
    //...
}

Once upon a time, I could do this:

var client = new ElasticClient(connectionSettings);
//...
client.MapFromAttributes<ElasticsearchDocument>(TEST_INDEX, type);

But I can’t anymore. client.Map<ShareDriveDocument>(m => m.MapFromAttributes()); triggers a runtime error. I suspect this is because m.MapFromAttributes() is a 0.12.* thing.

How do I accomplish this in 1.0?

@nasreekar I’ve opened #2085 to better handle attachments.

@nasreekar Take a look at the NEST 2.x documentation, specifically the documentation on Automapping and on breaking changes between 1.x and 2.x.
