Major refactor to eliminate MessagePack from SignalR messaging.
All serialization now uses explicit binary methods (.ToBinary/.BinaryTo)
and Brotli-compressed JSON, managed via a new SignalRSerializationHelper.
Custom stream classes and MessagePack attributes are removed.
API is now consistent, type-safe, and easier to maintain.
Test code and all message handling updated to use the new model.
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.
- Fix: Ensure property names and skipped strings are interned during binary deserialization, preventing interned string index mismatches.
- Add: Extensive regression tests for string interning edge cases, including property mismatch (server has more properties than client), deeply nested objects, repeated/unique strings, and empty/null handling.
- Add: New test DTOs and infrastructure for property mismatch scenarios.
- Update: SignalR test helpers and services to support both JSON and Binary serialization in all tests.
- Improve: SignalRRequestModelPool now initializes models on Get().
- These changes address production bugs and ensure robust, consistent string interning and property skipping in AcBinarySerializer.
Introduces SignalResponseBinaryMessage for efficient binary serialization of response data alongside existing JSON support. Adds utilities to detect serializer type and updates both server and client logic to handle JSON or binary formats automatically. Refactors response creation, logging, and deserialization for consistency and performance. Updates benchmarks and ensures all MessagePack operations use ContractlessStandardResolver.Options. Improves robustness and backward compatibility in client callback handling.
Major overhaul of JSON serialization/deserialization:
- Added AcJsonDeserializationException for clearer error reporting.
- Robust JSON validation, type checking, and double-serialization detection.
- Fast-path primitive (de)serialization for all common .NET types.
- Direct support for Dictionary<TKey, TValue> and improved collection handling.
- Enhanced $id/$ref reference resolution and in-place merging.
- Optimized property metadata caching and filtering.
- Comprehensive error handling with detailed messages.
- Extensive new tests for primitives, collections, references, and error cases.
- Benchmarks for serialization, deserialization, and merge scenarios.
SignalR infrastructure improvements:
- Refactored AcSignalRClientBase/AcWebSignalRHubBase for testability (virtual methods, test constructors).
- Added SignalRRequestModelPool for efficient request/response tracking.
- Improved parameter deserialization and IdMessage handling.
- New tags (PingTag, EchoTag) for SignalR messaging.
New test and benchmark infrastructure for SignalR:
- Shared test models and data factories for DTOs, primitives, and complex graphs.
- In-memory, dependency-free SignalR client/hub for round-trip testing.
- Exhaustive test suites for message processing, method invocation, and edge cases (including prior production bugs with Task<T>).
- Benchmarks for SignalR serialization, deserialization, and round-trip performance.
Other changes:
- Improved TaskHelper.WaitTo/WaitToAsync with more accurate polling and cancellation support.
- ExtensionMethods.InvokeMethod now properly unwraps Task/ValueTask results.
- General code cleanup, improved comments, and removal of obsolete code.
- Project references updated for shared test/benchmark infrastructure.
These changes deliver a robust, high-performance, and fully tested JSON/SignalR (de)serialization system, ready for production and advanced testing scenarios.
