Nest: how to add properties to objects for indexing?

Serilog sink for Elasticsearch defines a class LogEvent, fills its properties and sends it for indexing. This class has several top level scalar properties, but the most interesting part is the dictionary (name to value) of dynamic properties, which is declared like this:

    [JsonProperty(PropertyName = "fields")]
    public IDictionary<string, object> Properties { get; set; }

If there are dynamic properties “One” and “Two” what I get in Elasticsearch is “fields.One” and “fields.Two”.

The big question is how to get rid of “fields” prefix?? I want dynamic properties to be added at the top level and be accessible without any prefix, the same way as scalar properties of the class are.

I keep banging my head against the wall, but cannot figure how to do it. Could you help please?

Thank you! Konstantin

Greg, I finally found one line solution! Just put [JsonExtensionData] attribute on the Dictionary<string, object> and desired behavior is achieved automagically!
