```csharp
public static ISerializerBuilder AddNewtonsoftJsonSerializer(this ISerializerBuilder serializerBuilder, Func<Type, bool> isSerializable, Func<Type, bool> isCopyable, Action<OptionsBuilder<NewtonsoftJsonCodecOptions>> configureOptions)
```

Adds support for serializing and deserializing values using `Newtonsoft.Json.JsonSerializer`.

### Parameters

- `serializerBuilder` (`ISerializerBuilder`): The serializer builder.
- `isSerializable` (`Func<Type, bool>`): A delegate used to indicate which types should be serialized by this codec.
- `isCopyable` (`Func<Type, bool>`): A delegate used to indicate which types should be copied by this codec.
- `configureOptions` (`Action<OptionsBuilder<NewtonsoftJsonCodecOptions>>`): A delegate used to configure the options for the JSON serializer.
