Null Object Ref Error when creating index

[Jonesie]

Hi
Ive just updated my nuget of Nest to the latest version 0.11.1.0 from 0.9.20.6 and I now get a null object ref creating the index. My code is unchanged, but maybe it was never right. I've also updated Json.Net to v 5.0.6.2 and the call stack indicated that the JsonSerializer is where its failing.

The call stack is thus:

...

My Code to create the index is below:

     var settings = new IndexSettings();
            settings.Similarity = new SimilaritySettings();
            settings.NumberOfReplicas = _configuration.Replicas;
            settings.NumberOfShards = _configuration.Shards;
            settings.Add("index.refresh_interval", "10s");
            settings.Add("merge.policy.merge_factor", "10");
            settings.Add("search.slowlog.threshold.fetch.warn", "1s");
            settings.Analysis.Analyzers.Add(new KeyValuePair<string, AnalyzerBase>("keyword", new KeywordAnalyzer()));
            settings.Analysis.Analyzers.Add(new KeyValuePair<string, AnalyzerBase>("simple", new SimpleAnalyzer()));

     var idxRsp = client.CreateIndex(_settings.SearchIndexName, settings);

Looking at this a little closer it appears to be something to do with the field mappings. The TypeNameMarket is null.
I'm creating mappings by reading a definition in XML (not directly from Poco's), eg: new StringMapping() { Name = fieldname, Index = idx, Store = field.Store };

The help/docs say to use TypeMappingProperty but this is marked as obsolete.

Hey Jonesie,

I think I am missing part of the puzzle, can you check the attached commit's unit test ?
