Note

Cumulative public API diff .NET 10 GA → .NET 11 GA. The report files are labeled for GA and use the .NET 11 RC 3 reference packs as a stand-in for the GA API surface, based on the assumption that RC 3 and GA have the same API surface.

Ready for Review — .NET 11 is code complete. The report was generated manually because the API Diff Orchestrator could not process the rtm version suffix. The workflow was not changed.

10.0 GA (10.0.0) → 11.0 GA (RC 3 reference-pack build 11.0.0-rc.3.26522.148) — cumulative major-to-major diff.

How this was generated

Generated locally with release-notes/RunApiDiff.ps1 / Microsoft.DotNet.ApiDiff.Tool version 11.0.100-rc.3.26522.148.

  • Baseline: 10.0.0 from https://pkgs.dev.azure.com/dnceng/public/_packaging/dotnet-public/nuget/v3/index.json
  • Target reference packs: 11.0.0-rc.3.26522.148 from https://pkgs.dev.azure.com/dnceng/public/_packaging/dotnet11/nuget/v3/index.json
  • Target source commit: 5254d8bcf59917edc1e1abc33bdf2442b77b1c70
  • Reports refreshed: 2026-11-10
  • Automation state updated: 2026-11-10T10:33:12Z
  • Report and index files: 102 (103 Markdown files including this README)

The target packages were compared to the public dotnet11 feed. WindowsDesktop pack reconciliation found that the SDK-installed WPF assemblies differed from the feed package only in BuiltBy assembly metadata; the API surface matched. EditorBrowsableAttribute changes are excluded by the repository's configured API-diff exclusions. See the report README for comparison scope and further details.

The RC 3 = GA API-surface equivalence is an assumption supplied for this update; GA packages were not independently diffed. The RunApiDiff.ps1 workflow was not changed.

Status

code-complete — API diff generation is finished and the PR is ready for area-owner review.
