Selecting a NamingStrategy when using a JsonConverter on a class property

Okay, this appears to work:

[JsonProperty("type")] 
[JsonConverter(typeof(StringEnumConverter), 
     converterParameters:typeof(CamelCaseNamingStrategy))]
public ChartType ChartType { get; }  

As NamingStrategy is a property of the StringEnumConverter it's applied using the converterParameters parameter. This got my desired output. I think an example of this would be useful in Newtonsoft documentation.

Another possible solution is using JsonSerializerSettings

var settings = new JsonSerializerSettings
{
    Converters = new List<JsonConverter> {
        new StringEnumConverter(new CamelCaseNamingStrategy())
    }
};
var result = JsonConvert.SerializeObject(obj, settings);

This works for me for enabling camel casing on a single place in a .Net Core web api:

[JsonConverter(typeof(StringEnumConverter), true)]

Note that you can append constructor parameters to the type given by the first parameter and StringEnumConverter has the following overloaded constructor:

StringEnumConverter(bool camelCaseText)

Of course, enabling this globally is normally preferred, as discussed here for example.
