you dont need to include full package!
instead of
<PackageReference Include="Microsoft.WindowsAppSDK" Version="1.8.250907003" />

you need to include Microsoft.WindowsAppSDK.WinUI meta package

Thanks for the PR @licon4812! It seems your branch is quite behind the main, could you update it please?

@licon4812 I see your merge commit, but not sure why... Your branch still seems behind. Make sure it's upto date so then we can investigate at what point the actions are failing.

It is bizarre that I had to do it twice 🤣

The tests are failing because the project doesn’t include the WinAppSDK package and the sample apps are failing because they are on v1.6 too. Since the TableView project has moved to 1.8 and now only use the WinUI package, we need to add the WinAppSDK and Build Tools packages to the test and samples project.

@w-ahmad Currently, the tests work locally, just not on the pipeline agent

thanks for the updates @licon4812!
If the tests run fine locally, the issue is likely with the runner. Currently, the latest Windows runner uses VS 2022, so let's try running it with a VS 2026 runner instead.

@licon4812, the tests are now passing in CI. The issue was that the test runner wasn’t happy with the launch path, which I fixed in the latest commit.
