$# Changes in 7.1.0-beta.1
- Added: New package `MicroElements.AspNetCore.OpenApi.FluentValidation` for Microsoft.AspNetCore.OpenApi support (Issue #149)
 - Implements `IOpenApiSchemaTransformer` for .NET 9 and .NET 10
 - Supports all FluentValidation rules: Required, NotEmpty, Length, Pattern, Email, Comparison, Between
 - Handles AllOf/OneOf/AnyOf sub-schemas for polymorphic models
 - No dependency on Swashbuckle
 - User-facing API: `services.AddFluentValidationRulesToOpenApi()` + `options.AddFluentValidationRules()`
 - .NET 10: full nested validator support via `GetOrCreateSchemaAsync`
 - .NET 9: limited nested validator support (fallback to empty schema)
- Added: Sample project `SampleAspNetCoreOpenApi` demonstrating Microsoft.AspNetCore.OpenApi integration
- Added: ADR-001 documenting the architectural decision for AspNetCore.OpenApi support

# Changes in 7.0.6
- Fixed: `[AsParameters]` validation rules not applied on .NET 8 Minimal APIs (Issue #180)
 - On .NET 8, `ModelMetadata.ContainerType` is null for `[AsParameters]` decomposed parameters
 - Added `AsParametersHelper` fallback that resolves the container type via `[AsParameters]` reflection on `MethodInfo`
 - Applied fallback in both `FluentValidationOperationFilter` and `FluentValidationDocumentFilter`
 - Zero regression on .NET 9/10 where `ContainerType` is already populated

# Changes in 7.0.5
- Added: `RemoveUnusedQuerySchemas` option (default: `true`) to control cleanup of
 container type schemas for `[FromQuery]`/`[AsParameters]` types (Issue #180)

# Changes in 7.0.4
- Fixed: `[AsParameters]` types in minimal API and `[FromQuery]` container types create unused schemas in `components/schemas` (Issue #180)
- Added: Support for keyed DI services (Issue #165)
 - Validators registered via `AddKeyedScoped`, `AddKeyedTransient`, `AddKeyedSingleton` are now discovered automatically
- Removed: Deprecated `FluentValidation.AspNetCore` package reference (Issue #164)
 - Replaced with `FluentValidation.DependencyInjectionExtensions` 12.0.0

# Changes in 7.0.3
- Fixed: NullReferenceException when models contain nested object properties (Issue #176 extended)
 - Handle `OpenApiSchemaReference` for nested class properties in `OpenApiRuleContext`
 - Add safe `TryGetValue` check in `NSwagRuleContext`
