[LOADED_DOCS: 3 files, no new loads]
NativeAOT: full DAMs propagation, trimmer-safe serializers - Propagate [DynamicallyAccessedMembers] from all public Serialize<T>/Deserialize<T> APIs through all type/property metadata and factories, centralizing requirements in TypeMetadataBase.RequiredMembers. - Add [UnconditionalSuppressMessage] for known trimmer blind spots (polymorphism, inheritance, nested types) with detailed justifications. - Update all internal delegate/factory signatures to preserve DAMs context. - Annotate public APIs for AOT safety; document consumer requirements for SGen or rooted model assemblies. - Update BINARY_FEATURES.md with NativeAOT/trimmer compatibility, guidance, and limitations. - Adjust benchmark project for AOT/JIT parity and add i18n test data. - No breaking API changes; SGen and Runtime paths remain, now fully AOT-compatible.

Expression.Compile during JIT testing — Release benchmark numbers measure reflection, not

|

> Full SGen architecture, bridge methods, generated code patterns, wrapper slots: `BINARY_SGEN.md`
|
||||
|
||||
## NativeAOT Compatibility
|
||||
|
||||
Both execution modes work under NativeAOT publish. SGen is the recommended path; Runtime works but is significantly slower.
|
||||
|
||||
| Path | AOT compatible? | Performance vs JIT | Recommendation |
|
||||
|------|-----------------|--------------------|----|
|
||||
| **SGen** (`[AcBinarySerializable]` + `UseGeneratedCode=true`) | ✅ Full | Same as JIT | Production AOT default |
|
||||
| **Runtime** (no attribute or `UseGeneratedCode=false`) | ✅ Functional | ~5-7x slower than SGen | Fallback for unattributed types |
|
||||
|
||||
### Two-axis AOT strategy
|
||||
|
||||
NativeAOT has two distinct constraints — both must be addressed for the Runtime path to work:
|
||||
|
||||
1. **Dynamic code generation prohibited.** `Expression.Compile()` and `Reflection.Emit` fail under AOT (no JIT engine in the binary). The 7 property-accessor + constructor factories in `AcSerializerCommon` use `if (!RuntimeFeature.IsDynamicCodeSupported)` runtime guards to fall back to plain reflection delegates (`PropertyInfo.GetValue/SetValue`, `ConstructorInfo.Invoke`).
|
||||
|
||||
2. **Reflection metadata trim.** The trimmer drops `Type.GetConstructor()` / `Type.GetProperties()` metadata for types not statically referenced. The library propagates `[DynamicallyAccessedMembers(PublicParameterlessConstructor | PublicProperties)]` from the public `Deserialize<T>` / `Serialize<T>` entry points down through the metadata classes. The `RequiredMembers` constant on `TypeMetadataBase` is the single source of truth for the DAMs requirement.
|
||||
|
||||
### Documented trimmer blind spots
|
||||
|
||||
Two well-known limitations require consumer cooperation:
|
||||
|
||||
- **Polymorphism via `obj.GetType()`** — `WritePropertyOrSkip` writes the runtime concrete type for polymorphic properties; the trimmer cannot follow `GetType()` flow. Consumer must root polymorphic concrete types: either via `[AcBinarySerializable]` on each (SGen path covers them) or `<TrimmerRootAssembly>` for the data-model assembly. The IL2072 warning is suppressed at this site with documented justification.
|
||||
- **Nested types via property-type chain** — `List<TestOrderItem>` element type extracted via `Type.GetGenericArguments()` loses DAMs context. Same mitigation: `[AcBinarySerializable]` on each nested type, or `<TrimmerRootAssembly>`. The IL2072/IL2075 warnings are suppressed at the relevant sites with documented justification.
|
||||
|
||||
### Consumer guidance for AOT publish
|
||||
|
||||
- Annotate every type in the serialization graph with `[AcBinarySerializable]` — SGen path is AOT-clean and ~5-7x faster than the Runtime fallback.
|
||||
- Or, for unattributed types: add `<TrimmerRootAssembly Include="MyDataModel" />` in the consumer's csproj to keep reflection metadata for the data-model assembly intact (cost: larger AOT binary).
|
||||
- The `MessagePackSerializer.Standard` resolver has the same `Reflection.Emit` problem — use MessagePack source generators or skip MessagePack under AOT (the AcBinary benchmark project does the latter via `#if !AYCODE_NATIVEAOT`).
|
||||
- `System.Text.Json` reflection mode similarly requires `JsonSerializerIsReflectionEnabledByDefault=true` AND consumer awareness; for AOT the source-gen path is preferred.
|
||||
|
||||
### Verified
|
||||
|
||||
The full benchmark suite (Small/Medium/Large/Repeated Strings/Deep Nested) runs cleanly under NativeAOT publish on Windows x64 + .NET 9. AcBinary SGen retains its **+12-35% speed and -22-33% wire-size advantage over MemoryPack** under AOT, identical to JIT. Runtime path is functional but ~5-7x slower (reflection-delegate overhead).
|
||||
|
||||
## Property Ordering

## ACCORE-BIN-T-K9E4: `[RequiresDynamicCode]` + `[RequiresUnreferencedCode]` on Runtime-only methods
|
||||
**Priority:** P3 · **Type:** Refactor · **Related:** `BINARY_FEATURES.md#nativeaot-compatibility`
|
||||
|
||||
The Runtime path (factories in `AcSerializerCommon` + wrapper-based deserialize fallback in `AcBinaryDeserializer`) currently works under NativeAOT thanks to DAMs propagation + `RuntimeFeature.IsDynamicCodeSupported` guards, but the trimmer still emits warnings for the well-known blind spots (polymorphism via `obj.GetType()`, nested-type chain via generic argument extraction). The library suppresses these with `[UnconditionalSuppressMessage]` and documented justification.
|
||||
|
||||
A complementary signal would be to mark the Runtime entry points (or the factories themselves) with `[RequiresDynamicCode("AcBinary Runtime path uses Reflection.Emit / closed-generic instantiation; use [AcBinarySerializable] + SGen for NativeAOT.")]` and `[RequiresUnreferencedCode("...")]`. Effect:
|
||||
|
||||
- AOT publish in consumer's project surfaces a warning at the call site → consumer chooses SGen or accepts the Runtime cost
|
||||
- Mirrors the System.Text.Json reflection-mode pattern (`[RequiresDynamicCode]` on `JsonSerializer.Serialize<T>` overloads)
|
||||
- One-codebase, no NuGet split needed
|
||||
- Cheap implementation — attribute placement only
|
||||
|
||||
**Coordination:** `[RequiresDynamicCode]` is contagious; every caller must either propagate it or suppress with `[UnconditionalSuppressMessage]`. Scope:
|
||||
- Public `Serialize<T>` / `Deserialize<T>` entry points stay attribute-free (consumer-facing)
|
||||
- Runtime fallback methods get the attribute (contained inside the library)
|
||||
- The DAMs annotations we already have stay — they're orthogonal (one prevents trim, the other warns about JIT-only behavior)
|
||||
|
||||
**Acceptance:**
|
||||
- Consumer's AOT publish surfaces a IL2026/IL3050 warning when `UseGeneratedCode=false` is set or an unattributed type is deserialized
|
||||
- SGen path is warning-free
|
||||
- Library compiles 0 warnings (suppressions added at the propagation barrier)
|
||||
- `BINARY_FEATURES.md` NativeAOT Compatibility section updated to mention the explicit warning signal
|
||||
|
||||
## ACCORE-BIN-T-A2J7: Optional `AyCode.Core.Aot` NuGet variant (SGen-only build)
|
||||
**Priority:** P3 · **Type:** Feature · **Related:** `BINARY_FEATURES.md#nativeaot-compatibility`, `ACCORE-BIN-T-K9E4`
|
||||
|
||||
Binary-size-sensitive AOT consumers (Blazor WASM, MAUI mobile, embedded, container-trimmed) benefit from a smaller library variant that strips the Runtime fallback path entirely. Estimated savings: ~80-150 KB of native code (~25-60 KB compressed wire size for WASM publish).
|
||||
|
||||
**Strippable code in the `.Aot` variant:**
|
||||
|
||||
| Component | LOC | Purpose | Removable in Aot? |
|
||||
|---|---|---|---|
|
||||
| `AcSerializerCommon.Create*` (7 factory methods + Expression-tree code) | ~150 | Runtime delegate compilation | ✅ Yes |
|
||||
| `TypeMetadataBase` runtime metadata path (`CompiledConstructor`, IdGetters via Expression.Compile) | ~300 | Reflection-based metadata | ✅ Yes |
|
||||
| `AcBinaryDeserializer` wrapper-based runtime fallback (`PopulateObjectPropertiesIndexed`, `ReadObjectCoreWithWrapper` non-SGen branches, `CreateInstance(type)` Activator-fallback) | ~500 | Runtime polymorphic dispatch | ✅ Yes |
|
||||
| Property accessor runtime delegate fields (`_dynamicGetter`, typed getter/setter caches outside SGen) | ~150 | Boxed property access | ✅ Yes |
|
||||
| `System.Linq.Expressions` transitive dependency | — | Expression-tree IL emission | ✅ Yes (when nothing else in graph uses it) |
|
||||
|
||||
**Implementation sketch** (avoid `#if`-erdő via file-level split):
|
||||
|
||||
```
|
||||
AyCode.Core/Serializers/
|
||||
AcSerializerCommon.cs // SGen-safe shared parts
|
||||
AcSerializerCommon.Runtime.cs // 7 Create* factory methods only here
|
||||
AcBinaryDeserializer.cs // SGen path
|
||||
AcBinaryDeserializer.Runtime.cs // wrapper-based runtime fallback path
|
||||
TypeMetadataBase.cs // SGen-safe metadata
|
||||
TypeMetadataBase.Runtime.cs // Expression.Compile-based ctor + accessor wiring
|
||||
```
|
||||
|
||||
Two `.csproj` files:
|
||||
- `AyCode.Core.csproj` — full package (current); includes all files
|
||||
- `AyCode.Core.Aot.csproj` — `<Compile Remove="**/*.Runtime.cs" />`; sets `<PackageId>AyCode.Core.Aot</PackageId>`; same version as full
|
||||
|
||||
**Trade-offs:**
|
||||
|
||||
- ✅ No `#if` directives in business code — physically separate file groups
|
||||
- ✅ Source mostly shared via SDK include/exclude semantics
|
||||
- ✅ DAMs annotations and trim-suppressions only land in the full package; `.Aot` variant is genuinely trim-clean by construction
|
||||
- ✅ "Strict SGen" semantics in `.Aot`: a non-SGen type at deser time throws clearly instead of silently falling back. Marketing positioning: "guaranteed SGen path, no hidden slow lane".
|
||||
- ⚠️ Two NuGet IDs, two changelogs, version sync (CI-automatable)
|
||||
- ⚠️ Consumer must pick the right package — wrong choice = breaking switch later
|
||||
|
||||
**Coordination:**
|
||||
- Land `ACCORE-BIN-T-K9E4` first (`[RequiresDynamicCode]` attributes) — if that pattern handles the consumer-side scenarios well, `.Aot` may not be needed
|
||||
- The current Runtime fallback code is already well-isolated (mostly in `AcSerializerCommon` factories + `AcBinaryDeserializer` wrapper-based methods), so the file-split refactor is mechanically straightforward
|
||||
- Marketing decision: is binary size a central pillar? If yes, `.Aot` is a NuGet differentiator; if not, `K9E4` alone is enough
|
||||
|
||||
**Acceptance:**
|
||||
- `AyCode.Core.Aot.csproj` produces a NuGet ~25-60 KB smaller than `AyCode.Core` after compression
|
||||
- `.Aot` build emits zero IL/AOT trim warnings (no suppressions needed because the Runtime path code is physically removed)
|
||||
- Round-trip tests pass on `.Aot` for all SGen types
|
||||
- `.Aot` throws a clear `InvalidOperationException` (not `MissingMethodException`) when a non-`[AcBinarySerializable]` type is encountered at deser time
|
||||
- `BINARY_FEATURES.md` NativeAOT Compatibility section documents both packages and when to choose which
