- Add batch update support for IAcObservableCollection during deserialization to suppress per-item notifications and fire a single reset event.
- Throw AcJsonDeserializationException with a clear message if a type lacks a parameterless constructor during deserialization.
- Enhance IsGenericCollectionType to recognize more collection types, including ObservableCollection<T> and custom IList<T> implementations.
- Improve array and collection deserialization logic to better handle target types and fall back to List<T> if needed.
- In AcObservableCollection, catch and ignore ObjectDisposedException in event handlers to prevent errors from disposed subscribers.
- Remove redundant batch update logic from AcSignalRDataSource; rely on deserializer's handling.
- Set SkipNegotiation = true in SignalR client options for WebSockets-only optimization and comment out automatic HubConnection.StartAsync() for more controlled connection management.
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.
- Introduced AcJsonSerializer/Deserializer: fast, reflection-free, streaming JSON with optimized $id/$ref handling and Base62 IDs.
- Default serialization now uses new serializers; falls back to Newtonsoft for complex cases.
- Extensive type/property caching for performance and thread safety.
- Refactored MergeContractResolver and collection merge logic; all merge/populate operations use centralized caches.
- AcObservableCollection and AcSignalRDataSource are now fully thread-safe and support batch operations.
- SignalResponseMessage<T> supports lazy deserialization and direct JSON access.
- Added comprehensive unit tests and benchmarks for serialization, deserialization, and collection operations.
- Updated .gitignore and solution files; refactored core classes for clarity and performance.
