A custom JSON converter library with some useful features for ASP.NET client-server application.
It serializes objects to a JSON string, using the provided interfaces as templates, and including attributed fields not included in the interfaces. This allows you to pass objects from the storage layer through the model to the client, hiding specific data, while still storing it for postback from the client.
It deserializes a JSON string into objects, reusing existing objects as targets if possible. This avoids creating an intermediate list of objects when populating an ObservableCollection on the WPF client, and reduces the overhead of creating multiple objects in memory and the garbage collector.
