ProtocolJsonSerializer Class

Provides a way to turn off the {channelId}:{product} notation. If false, ChannelId.ToString() is just the {channelId} value. However, serialization of the ProductInfo Entity is still accounted for. ChannelId.SubChannel is still populated with the ProductInfo.Id value in any case. It is not recommended to set false without guidance.

Maintains a mapping of entity type names to their corresponding Type objects.

Prepends a IJsonTypeInfoResolver (e.g., a source-generated JsonSerializerContext) to the resolver chain used by SerializationOptions. The resolver is consulted before any previously registered resolvers and before the reflection fallback. Call from a SerializationInitAssemblyAttribute-decorated Init() method.

Applies a transformation function to SerializationOptions, replacing it with the result. This is an advanced escape hatch — prefer ApplyExtensionConverters(IList<JsonConverter>) or AddTypeInfoResolver(IJsonTypeInfoResolver) for typical extensions.

Registers an imperative ActivityTypeResolver for custom Activity resolution scenarios that the declarative ActivityTypeAttribute discriminators cannot express. The resolver receives a private Utf8JsonReader copy positioned at the Activity's StartObject (so it can discriminate on any property, including nested ones) plus the well-known peeked discriminators for convenience. Resolvers are consulted (in registration order) before declarative registrations; the first resolver to return a non-null type wins.

Registers custom Activity subclasses for polymorphic deserialization. Each type must derive from Activity and be annotated with one or more ActivityTypeAttribute. Each attribute declares the discriminators (type, and optionally channelId and/or name) that an inbound Activity must match for the subclass to be used.

Object to JsonElement conversion.

Decompose an object into its constituent JSON elements.

Convert an object to the desired type using serialization and deserialization.
