Add YamlDotNet source generator infrastructure for Native AOT support#4688
Conversation
- Added Vecc.YamlDotNet.Analyzers.StaticGenerator package - Changed init properties to set properties to support source generator - Created GitVersionConfigurationStaticContext for AOT compatibility - Updated ConfigurationSerializer to use static serializer/deserializer - Updated PublicAPI.Unshipped.txt with generated API surface Co-authored-by: arturcic <1760506+arturcic@users.noreply.github.com>
The YamlDotNet source generator has limitations: - Doesn't honor custom type inspectors for property naming - Limited support for dynamic types - The static context is kept for future use when generator improves All tests now pass with the regular serializers.

@copilot I actually need to use the source generator version, and I will later check the AOT

Pull Request Overview
This PR adds YamlDotNet source generator infrastructure to prepare GitVersion for Native AOT (Ahead-of-Time) compilation support. The infrastructure is implemented but not actively used due to current limitations in YamlDotNet's source generator capabilities.
- Added
Vecc.YamlDotNet.Analyzers.StaticGeneratorv16.3.0 package reference and createdGitVersionConfigurationStaticContextclass - Changed property accessors from
internal inittointernal setacross all configuration classes to support source generator requirements - Added documentation explaining current limitations and future migration path

Overview
This PR adds the YamlDotNet source generator infrastructure to prepare GitVersion for Native AOT (Ahead-of-Time) compilation support, as outlined in Using the YamlDotNet Source Generator for Native AOT.
Changes
1. Source Generator Package
Vecc.YamlDotNet.Analyzers.StaticGeneratorv16.3.0 package referenceGitVersionConfigurationStaticContextclass with[YamlStaticContext]and[YamlSerializable]attributes for main configuration types2. Property Accessor Updates
Changed
internal inittointernal setfor all configuration properties to support source generator requirements:BranchConfiguration(14 properties)GitVersionConfiguration(21 properties)IgnoreConfiguration(4 properties)PreventIncrementConfiguration(3 properties)This change maintains encapsulation (internal setters) while providing flexibility for serialization and future source generator use.
3. Updated Public API Surface
Added generated types to
PublicAPI.Unshipped.txt:GitVersionConfigurationStaticContextStaticTypeInspectorand related methodsCurrent Status
While the infrastructure is in place, the static serializer/deserializer is not actively used due to current limitations in YamlDotNet's source generator (v16.3.0):
StaticTypeInspectordoesn't honor custom type inspectors, which GitVersion requires forJsonPropertyNameattribute mappingDictionary<object, object?>used in override configurationsThe
ConfigurationSerializercurrently uses regularDeserializerBuilder/SerializerBuilderwith a comment explaining the situation. The static context is instantiated but kept ready for future use.Testing
✅ All 82 configuration tests pass (net8.0 and net9.0)
✅ Full backward compatibility maintained
✅ No breaking changes to existing functionality
Documentation
Added
YAMLDOTNET_SOURCE_GENERATOR.mddocumenting:Future Work
When YamlDotNet's source generator improves support for custom type inspectors and complex types, we can enable it in
ConfigurationSerializer.csby switching toStaticDeserializerBuilder/StaticSerializerBuilder.Related
