Localized file check-in by OneLocBuild Task: Build definition ID 679: Build ID 3009486

[dotnet-bot]

This is the pull request automatically created by the OneLocBuild task in the build process to check-in localized files generated based upon translation source files (.lcl files) handed-back from the downstream localization pipeline. If there are issues in translations, visit https://aka.ms/icxLocBug and log bugs for fixes. The OneLocBuild wiki is https://aka.ms/onelocbuild and the localization process in general is documented at https://aka.ms/AllAboutLoc.

Copilot Code Review

Holistic Assessment

Motivation: Automated OneLocBuild PR syncing localized .xlf translation files. Standard localization pipeline process for 39 files across three libraries.

Approach: Removes obsolete translation entries, adds new state="new" entries for the downstream translation pipeline, and updates source text for entries with changed English strings.

Summary: ⚠️ Needs Human Review. The System.Runtime.InteropServices changes (13 files) are correctly in sync with main. However, the Microsoft.Extensions.Logging.Abstractions (13 files) and System.Text.Json (13 files) changes reflect a future state of source strings that has not yet landed on main. A human reviewer familiar with the OneLocBuild pipeline should confirm whether the corresponding .resx updates will land before or alongside this PR.

Detailed Findings

Detailed Findings

✅ System.Runtime.InteropServices — Correctly in sync with main

Verified the .resx on main (SHA d6c7fb69f882c3ffd49de58dd009330e2a915402):

• The 3 removed InstancePropertyDeclaredInInterface* entries are absent from the current .resx (removed by PR Add support for properties in COM source generator #128869).
• All 12 new entries (InvalidPropertyDeclarationOnGeneratedComInterface*, MarshalAttributeOnDefaultImplementedComInterfaceMember*, MarshalUsingOnPropertyAccessorMustSpecifyType*, PropertyAccessorsMustBeAllOrNothing*) are present in the current .resx.
• Source text in each new .xlf entry matches the .resx values exactly.

⚠️ Microsoft.Extensions.Logging.Abstractions — Version skew with main

The .resx on main still contains entries being removed from .xlf, and source text changes don't match:

Issue	Details
Entries removed from .xlf but still in .resx	InvalidLoggingMethodParameterOut*, InvalidLoggingMethodParameterParams*, InvalidLoggingMethodParameterRefStruct*, LoggingMethodHasAllowsRefStructConstraintMessage, LoggingUnsupportedLanguageVersion*, MalformedFormatStringsTitle, PrimaryConstructorParameterLoggerHidden*, ShouldntReuseEventNames*
New entry not in .resx	LoggingMethodIsGenericMessage
Source text mismatch	.resx says must be 'partial' / must return 'void' / must be 'static' (with quotes); .xlf changes to must be partial / must return void / must be static (without quotes)
Also changed	MalformedFormatStringsMessage source text changed; RedundantQualifierInMessageMessage single-quotes removed

The last commit to this .resx on main (Feb 27, 2026, PR #124960) added these quotes to improve translation quality. The OneLocBuild pipeline appears to be running against a build that reverses this change.

⚠️ System.Text.Json — Version skew with main

The .resx on main still contains all entries being removed from .xlf:

Issue	Details
Entries removed from .xlf but still in .resx	DerivedJsonConverterAttributesNotSupported*, FastPathPolymorphismNotSupported*, JsonConverterAttributeInvalidType*, JsonIgnoreConditionAlwaysInvalidOnType*, JsonSerializableAttributeOnNonContextType*, JsonStringEnumConverterNotSupported*, JsonUnsupportedLanguageVersion*, OpenGenericDerivedTypeCouldNotBeResolved*, Polymorphism_OpenGeneric_Reason_* (5 entries), TypeContainsRefLikeMember*, UnionCaseTypesNotClassifiable*, UnionTypeShapeNotSupported*
New entries not in .resx	InitOnlyPropertyDeserializationNotSupportedFormat, InitOnlyPropertyDeserializationNotSupportedTitle
Source text mismatch	DuplicateTypeNameMessageFormat: .resx says named '{0}' (with quotes); .xlf changes to named {0} (without quotes)

✅ Structural consistency across language files

All changes are applied identically across all 13 language-specific .xlf files for each library. New entries correctly use state="new" with English source text as target (standard OneLocBuild pattern).
