Replaces legacy JSON-in-Binary parameter envelopes with a length-prefixed, per-parameter binary format for all client→server calls. Introduces SerializeParametersToBinary and DeserializeParametersFromBinary for type-safe, zero-copy parameter handling. Marks IdMessage, SignalPostJsonDataMessage, and related wrappers as obsolete. Updates all client CRUD/messaging helpers and server-side dispatch to use object[] binary serialization. Adds DataSerializerType to SignalReceiveParams for response format indication. Updates tests and documentation to reflect new protocol. BREAKING CHANGE: not compatible with previous JSON-in-Binary clients/servers.
Major protocol update: OnReceiveMessage now takes metadata (SignalReceiveParams) and payload (byte[]) as separate hub arguments, not a single envelope. Metadata is AcBinary-serialized; payload uses protocol fast-path. Updated all client/server code, interfaces, and docs. Added ISignalParams and SignalReceiveParams types. Improved AcBinaryHubProtocol diagnostics and made byte[] fast-path more robust. This enables clearer, more debuggable, and future-proof SignalR binary messaging.
- Changed default SignalR message serialization from JSON to binary.
- Updated AcSerializerType enum values: Binary=0, Json=1.
- Disabled string caching when intern table is present.
- Replaced Brotli with GZip for JSON compression in comments and logic.
- Refactored SignalResponseDataMessage deserialization for improved error handling.
- Introduced AcJsonSerializer/AcJsonDeserializer in AyCode.Core.Serializers.Jsons, optimized for IId<T> reference and circular reference handling.
- Added AcJsonSerializerOptions/AcSerializerOptions for configurable reference handling and max depth.
- Implemented fast-path streaming (Utf8JsonReader/Writer) with fallback to DOM for reference scenarios.
- Added type metadata/property accessor caching for performance.
- Provided robust object/collection population with merge semantics for IId<T> collections.
- Added AcJsonDeserializationException for detailed error reporting.
- Implemented UnifiedMergeContractResolver for Newtonsoft.Json, supporting JsonNoMergeCollectionAttribute to control merge behavior.
- Added IdAwareCollectionMergeConverter<TItem, TId> for merging IId<T> collections by ID.
- Included helpers for ID extraction and semantic ID generation.
- Added DeepPopulateWithMerge extension for deep merging.
- Optimized with frozen dictionaries, pre-encoded property names, and context pooling.
- Ensured compatibility with both System.Text.Json and Newtonsoft.Json.
Major refactor: all SignalR responses now use a single unified `SignalResponseDataMessage` type with binary payloads. JSON responses are Brotli-compressed for efficiency. Removed legacy JSON/Binary response types and MessagePack server-to-client serialization. Updated all serialization extensions for zero-allocation binary ops. Refactored client/server/data source/test code to use new message and serialization model. Improved deserialization robustness for primitives. Modernized and streamlined test suite.
