$# Changes in 7.1.3

• Fixed: $ref replaced with inline schema copy when using SetValidator with nested object types (Issue #198)
  • ResolveRefProperty (introduced in 7.1.2 for BigInteger isolation) replaced all $ref properties with copies, destroying reference structure in the OpenAPI document
  • Fix: snapshot $ref properties before rule application, restore them afterwards if no validation constraints were added by rules
  • BigInteger per-model constraints (Issue #146) continue to work correctly

Changes in 7.1.2

• Added: BigInteger support for min/max validation constraints in OpenAPI schema generation (Issue #146)
  • IsNumeric() and NumericToDecimal() now handle BigInteger values
  • BigInteger properties with GreaterThan, LessThan, InclusiveBetween, ExclusiveBetween rules produce correct minimum/maximum in Swagger
  • NSwag provider updated with the same BigInteger support
  • Out-of-range BigInteger values (exceeding decimal range) are handled gracefully via existing try/catch
• Fixed: Shared schema mutation when multiple models reference the same BigInteger type with different constraints (net10.0)
  • ResolveRefProperty creates an isolated shallow copy before applying rule mutations
  • Prevents $ref-based schema corruption across models in SchemaRepository
• Fixed: Replaced deprecated PackageLicenseUrl with PackageLicenseExpression (Issue #144)
• Fixed: Replaced deprecated PackageIconUrl with embedded PackageIcon

Changes in 7.1.1

• Fixed: Nested object validation not applied for [FromQuery] parameters (Issue #162)
  • When Swashbuckle decomposes [FromQuery] models with nested objects into flat parameters (e.g., operation.op), the full dot-path name was used for schema property matching instead of the leaf name (op)
  • EqualsIgnoreAll("operation.op", "op") compared "OPERATIONOP" vs "OP" and failed to match
  • Strip dot-path prefix using LastIndexOf('.') in both FluentValidationOperationFilter and FluentValidationDocumentFilter
  • Supports arbitrarily deep nesting (e.g., a.b.c → c)
• Added: SetNotNullableIfMinimumGreaterThenZero option to separately control nullable behavior for numeric Minimum constraints (Issue #154, ported from vchirikov fork PR #2)
  • Distinct from existing SetNotNullableIfMinLengthGreaterThenZero (for string MinLength)
  • Default: false (backward compatible)
• Fixed: SetNotNullableIfMinLengthGreaterThenZero option now works in NSwag provider (Issue #154)
  • NSwagFluentValidationRuleProvider now accepts IOptions<SchemaGenerationOptions>
  • Rules NotEmpty, Length, Comparison, Between respect both nullable options
  • Feature parity across Swashbuckle, AspNetCore.OpenApi, and NSwag providers
• Improved: Comparison/Between rules now use SetNotNullableIfMinimumGreaterThenZero() which checks actual Minimum value instead of unconditionally setting not-nullable

Changes in 7.1.0

• 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)
• Fixed: AspNetCore.OpenApi.FluentValidation support for .NET 10 (Issue #149, PR #192)
• Added: Sample project SampleAspNetCoreOpenApi demonstrating Microsoft.AspNetCore.OpenApi integration
• Added: ADR-001 documenting the architectural decision for AspNetCore.OpenApi support
