Description

Type of Change

Erase all that don't apply.

###Summary -
I did a fresh git clone, and the playground app was not building or running. I used AI tools to help resolve the issue and am sending out this PR with the fixes. I understand that some of the changes are related to the recent VS Code version updates.

Why

The playground-composition app cannot be built or run locally using npx react-native run-windows from the packages/playground folder. Multiple issues in the solution file, project references, and build configuration cause cascading build failures. These affect anyone cloning the repo and attempting to run the composition playground.

Resolves - building and running the playground app locally

What

Added missing Global line in the .sln file (was causing autolink to corrupt the file).
Fixed duplicate SampleCustomComponent entry - updated path and removed ProjectSection block that confused autolink's detection.
Aligned SampleCustomComponent reference paths - .sln and .vcxproj pointed to the same project via different paths (symlink vs direct), causing parallel build collisions on PDB/tlog files.
Excluded @react-native-picker/picker from autolinking - it's UWP-only and incompatible with the composition (Win32) target.
Changed PlatformToolset from hardcoded v143 to $(DefaultPlatformToolset) for forward compatibility with newer VS versions.
Added /FS flag to SampleCustomComponent to prevent PDB write conflicts during parallel builds.
Disabled RestoreLockedMode for playground-composition to avoid NuGet lock file errors during local dev.

Screenshots

No UI changes

Testing

Verified npx react-native run-windows from packages/playground:

Builds successfully from clean state
App launches and runs

Changelog

Should this change be included in the release notes: No. Internal tooling/playground fix — does not affect published packages or end-user functionality.

Microsoft Reviewers: Open in CodeFlow

- Add missing 'Global' line to playground-composition.sln that caused autolink to corrupt the solution file (MSB5010) - Update SampleCustomComponent path to node_modules and remove ProjectSection to prevent autolink from adding duplicate entries (MSB5004) - Exclude @react-native-picker/picker from autolinking when targeting composition, as it is a UWP/Paper component incompatible with Win32/WinAppSDK (WindowsAppSDK transitive dependency error) - Use $(DefaultPlatformToolset) instead of hardcoded v143 in Playground-Composition.vcxproj and SampleCustomComponent.vcxproj for forward compatibility with newer VS versions Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

- Align ProjectReference in Playground-Composition.vcxproj to use the same node_modules path as the .sln, preventing parallel build collisions when MSBuild resolves the same project via two different paths (C1041/FTK1011) - Add /FS flag to SampleCustomComponent for synchronized PDB writes - Disable RestoreLockedMode for playground-composition local dev builds to prevent NU1004 errors from stale lock files Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
