How Can I Set Private Setters as the Default Behavior in Json.Net?

Setting Private Setters in Json.Net by Default

While Json.Net provides an attribute to explicitly handle private setters, the desire may exist to set this behavior as the default. While tweaking the source code is an option, there are alternative approaches to achieve this:

Using [JsonProperty] Attribute

If the sole purpose is to populate a readonly property during deserialization, applying the [JsonProperty] attribute suffices. For instance:

[JsonProperty]
public Guid? ClientId { get; private set; }

Constructor with Parameter

Consider providing a constructor with a parameter that matches the property, as shown below:

public class Foo
{
    public string Bar { get; }

    public Foo(string bar)
    {
        Bar = bar;
    }
}

This approach allows for serialization and deserialization:

string json = "{ \"bar\": \"Stack Overflow\" }";

var deserialized = JsonConvert.DeserializeObject<Foo>(json);
Console.WriteLine(deserialized.Bar); // Stack Overflow

Benefits of Constructor Approach:

• Eliminates the need for attribute decoration
• Applicable to both { get; private set; } and { get; } properties
