[build] `net11.0` target framework #10664

jonathanpeppers · 2026-01-06T18:42:30Z

This pull request updates the codebase to target .NET 11 as the default, including support for .NET 11.0-android, and upgrades related dependencies and documentation. It also improves CI scripts and configuration for the new target framework.

Target framework and SDK updates:

Set the default target framework to net11.0 and the stable target to net10.0 in Directory.Build.props and pipeline variables.
Added constants for latest and previous .NET target frameworks in XABuildConfig.cs.in.
Updated PREPARE_NET_FX in Makefile and improved workload manifest handling for net10 in xaprepare.

CI and build improvements:

Updated CI YAML templates to only run prepare-external-git-dependencies for non-forked PRs, improving security and reliability.
Added a new NuGet package source for dotnet-runtime.

Documentation and templates:

Updated documentation and issue templates to reference net11.0-android and use the new default target framework in examples.

Other configuration updates:

Set TargetsCurrent=true in Directory.Build.props as a temporary workaround for a known SDK issue.
Updated the default .NET SDK version for CI to 10.0.

These changes ensure the project is ready for .NET 11 development and testing, while maintaining support for .NET 10 as the stable release.

Changed the PREPARE_NET_FX variable from net9.0 to net10.0 to target the newer .NET framework version in the build process.

Added PackageDownload entries for Microsoft.NET.Workload.Mono.ToolChain.net10 and Microsoft.NET.Workload.Emscripten.net10 to support .NET 10 workloads in the package-download.proj file.

Eliminated PackageDownload entries for net6, net7, net8, and net9 Mono and Emscripten manifests from package-download.proj, retaining only the current and net10 versions. This streamlines the package list and focuses on supported manifest versions.

Commented out PackageDownload entries for Mono and Emscripten .net10 manifests that do not exist yet, adding TODO notes for future reference.
