Major overhaul of JSON serialization/deserialization:
- Introduce AcJsonSerializerOptions for reference handling and max depth
- Centralize type checks, primitive/collection logic in JsonUtilities
- Add depth limiting to serializer/deserializer (MaxDepth support)
- Make $id/$ref reference handling optional via options
- Unify and simplify public API (ToJson, JsonTo, CloneTo, CopyTo, etc.)
- Improve primitive, enum, and collection handling and caching
- Refactor contract resolver and merge logic to use new utilities
- Remove redundant code, centralize string escaping/unescaping
- Update all tests and benchmarks to use new API and options
- Fix minor bugs and improve error handling and validation
This modernizes and unifies the JSON infrastructure for better performance, flexibility, and maintainability.
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.
- Use compiled expression tree accessors for property get/set (AOT/WASM compatible, much faster than reflection)
- Add comprehensive WASM/AOT compatibility and SignalR parameter array tests
- Correctly handle $id/$ref for shared references; optimize reference resolution
- Always serialize empty collections as [], omit null collections
- Optimize primitive reading and type metadata caching
- Fix edge cases in array, primitive, and reference deserialization
- Ensure output matches Newtonsoft.Json for arrays and primitives
- Greatly expand test coverage for all major 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.
- Updated all projects to use `Newtonsoft.Json` v13.0.3 for consistency.
- Introduced `HybridReferenceResolver` for semantic and numeric ID handling.
- Refactored `SerializeObjectExtensions` to support deep JSON merging.
- Simplified `IId<T>` interface by removing `IEquatable<T>` constraint.
- Improved `AcSignalRDataSource` with robust `AddRange` and `CopyTo` methods.
- Added `JsonExtensionTests` for deep hierarchy, reference, and edge cases.
- Implemented `UnifiedMergeContractResolver` for custom JSON behavior.
- Optimized type/property caching with `TypeCache` and `CachedPropertyInfo`.
- Enhanced SignalR integration to fix primitive array deserialization issues.
- Introduced `JsonNoMergeCollection` attribute for replace-only collections.
- Added test DTOs and `TestDataFactory` for real-world scenario simulations.
- Improved performance with `ConcurrentDictionary` and `ObjectPool`.
- Fixed `$id`/`$ref` handling for non-semantic references and arrays.
