Detailed Description of the Pull Request / Additional comments

Dependency and SDK upgrades:

• Upgraded Microsoft.WindowsAppSDK and related packages (Base, Foundation, WinUI, Runtime, DWrite, InteractiveExperiences, Widgets, AI) to version 1.8.x in all relevant project files, including Directory.Packages.props, .vcxproj, .csproj, and packages.config files. This also involved updating import paths and error checks for the new package structure. [1] [2] [3] [4] [5] [6] [7] [8]
• Updated Microsoft.Web.WebView2 to version 1.0.3179.45 and Microsoft.Windows.SDK.BuildTools to 10.0.26100.4948 in Directory.Packages.props. [1] [2]

Build and packaging improvements:

• Enhanced the MSIX package selection logic in the build pipeline (job-build-project.yml) to prioritize platform-specific packages (x64/arm64) and provide clearer logging and error handling when no packages are found.
• Modified Microsoft.CmdPal.UI.csproj to disable Appx bundling and set a specific test directory for Appx packages during CI builds, improving build output organization.

These updates help ensure the project stays current with the latest SDKs and improves reliability and transparency in the build process.

Some files were automatically ignored 🙈

These sample patterns would exclude them:

^\Qsrc/modules/peek/Peek.UITests/TestAssets/4.qoi\E$
^src/modules/powerrename/PowerRenameUITest/testItems/

You should consider adding them to:

.github/actions/spell-check/excludes.txt

File matching is via Perl regular expressions.

To check these files, more of their words need to be in the dictionary than not. You can use patterns.txt to exclude portions, add items to the dictionary (e.g. by adding them to allow.txt), or fix typos.

To update file exclusions and remove the previously acknowledged and now absent words, you could run the following commands

... in a clone of the [email protected]:microsoft/PowerToys.git repository
on the shawn/testNewWinAppSDK branch (ℹ️ how do I use this?):

curl -s -S -L 'https://raw.githubusercontent.com/check-spelling/check-spelling/c635c2f3f714eec2fcf27b643a1919b9a811ef2e/apply.pl' |

git commit -m 'Update check-spelling metadata'

Forbidden patterns 🙅 (1)

In order to address this, you could change the content to not match the forbidden patterns (comments before forbidden patterns may help explain why they're forbidden), add patterns for acceptable instances, or adjust the forbidden patterns themselves.

These forbidden patterns matched content:

Should be fall back

\bfallback(?= to)\b

Pattern suggestions ✂️ (2)

You could add these patterns to .github/actions/spell-check/patterns.txt:

# Automatically suggested patterns

# hit-count: 1 file-count: 1
# marker to ignore all code on line
^.*/\* #no-spell-check-line \*/.*$

# hit-count: 1 file-count: 1
# marker to ignore all code on line
^.*\bno-spell-check(?:-line|)(?:\s.*|)$

Alternatively, if a pattern suggestion doesn't make sense for this project, add a #
to the beginning of the line in the candidates file with the pattern to stop suggesting it.

If the flagged items are 🤯 false positives

If items relate to a ...

• binary file (or some other file you wouldn't want to check at all).

  Please add a file path to the excludes.txt file matching the containing file.

  File paths are Perl 5 Regular Expressions - you can test yours before committing to verify it will match your files.

  ^ refers to the file's path from the root of the repository, so ^README\.md$ would exclude README.md (on whichever branch you're using).

• well-formed pattern.

  If you can write a pattern that would match it,
  try adding it to the patterns.txt file.

  Patterns are Perl 5 Regular Expressions - you can test yours before committing to verify it will match your lines.

  Note that patterns can't match multiline strings.
