Namespace LaunchDarkly.Sdk.Json

Helper classes and methods for interoperability with JSON.

The NuGet package containing these types is LaunchDarkly.CommonSdk. Normally you should not need to reference that package directly; it is loaded automatically as a dependency of the main SDK package.

Any LaunchDarkly SDK type that has the marker interface IJsonSerializable has a canonical JSON encoding that is consistent across all LaunchDarkly SDKs. There are three ways to convert any such type to or from JSON:

When using the System.Text.Json API, these types already have the necessary attributes to behave correctly.
You may use the LdJsonSerialization methods SerializeObject<T>(T) and DeserializeObject<T>(String) to convert to or from a JSON-encoded string.

Earlier versions of the LaunchDarkly SDKs used Newtonsoft.Json for JSON serialization, but current versions have no such third-party dependency. Therefore, these types will not work correctly with the reflection-based JsonConvert methods in Newtonsoft.Json without some extra logic. There is an add-on package, LaunchDarkly.CommonSdk.JsonNet, that provides an adapter to make this work; alternatively, you can call SerializeObject<T>(T) and put the resulting JSON output into a Newtonsoft.Json.Linq.JRaw value.
