Migrate to Uno.Sdk by MartinZikmund · Pull Request #305 · CommunityToolkit/Tooling-Windows-Submodule

Depends on #304

^ Conflicts: ^ .github/workflows/build.yml

The job runs on ubuntu-latest but installed ios/maui workloads which aren't supported on Linux, failing at the install step. Uno.Sdk auto-filters the iOS TFM on Linux, so only android + wasm-tools are needed for the desktop/browserwasm heads this job builds. Also renamed the job from the misleading "uno-windows" back to "uno-linux". Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

The uno-linux job runs on ubuntu-latest and all its build steps use dotnet (slngen, dotnet build). The microsoft/setup-msbuild action is Windows-only and fails on Linux. Remove it. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

dotnet workload install ran at the repo root before global.json was copied there, so it installed android/wasm-tools for the runner's preinstalled SDK 10 band. The build is pinned to the 9.0.x band via global.json, where no workloads were present, causing NETSDK1147. Run the install from ./tooling so global.json scopes it to the right band.

The new Uno.Sdk head platform entry-point files (Desktop/WebAssembly/ Android/iOS) were missing the standard .NET Foundation license header. Consumers that enforce IDE0073 (file header required) as an error — like CommunityToolkit/Windows — fail to build the Uno head without them.

Pull request overview

This PR migrates the tooling “project heads” to use Uno.Sdk (primarily for WinUI 3 / Uno 6.x), updating build scripts and CI to generate/build the new Uno head alongside existing multi-target heads.

Changes:

Adds new Uno.Sdk-based heads for AllComponents and SingleComponent (desktop/wasm/android/ios scaffolding).
Updates Uno package/version management to support Uno 5.x for WinUI 2 and Uno 6.x for WinUI 3 via conditional props.
Updates generation scripts and GitHub Actions workflows to include/build the Uno.Sdk head and install required workloads.

CommunityToolkit.App.Shared/Renderers/Markdown/MarkdownTextBlock.cs:23

The Uno WASM MarkdownTextBlock polyfill is now excluded for WINUI3 builds. For Uno.WinUI WebAssembly (the new Uno.Sdk head), this will fall back to the non-WASM implementation (a plain TextBlock), which prevents markdown from being rendered.

#if HAS_UNO_WASM && !WINUI3
using Markdig;
using Uno.Foundation.Interop;
using Uno.UI.Runtime.WebAssembly;
#endif
