Considering the document { \"userName\": \"user1\" } stored in the User collection, and the following User class:
public class Use
In a similar case with Cosmos DB, I was able to set all properties to Camel case for my objects at the class declaration level, as in:
[JsonObject(NamingStrategyType = typeof(CamelCaseNamingStrategy))]
public class User
{
public string Id { get; set; }
public string UserName { get; set; }
}
This is how you tell NewtonSoft.Json to use Camel case for serializing.
