[C.I.] Autogenerate ignore set as artifact in C.I.

[workgroupengineering]

What would you like to be added:

When performing C.I. task Pack NuGet, if there are any changes on the API surface it generates ingorediff.xml

Why is this needed:

Avoid mistake in editing PackageDiffIgnore.xml, only copy and panse from ingorediff.xml to PackageDiffIgnore.xml.

For which Platform:

• WebAssembly
• Android
• iOS
• macOS (AppKit)
• Mac Catalyst
• Skia
  • WPF
  • GTK (Linux)
  • Linux Framebuffer
  • Tizen
• Windows
• Build tasks
• Solution Templates

Anything else we need to know?

We could experiment with moving this check to GitHub Actions, which will comment on the PR with the necessary changes to PackageDiffIgnore

[workgroupengineering]

In this PR i have add the ability to generate Comment with changes on GitHub PR like UI Test Screenshot Comparision.

Is there a nightly feed of Uno.PackageDiff for using it in the Uno Repository?

[Youssef1313]

like UI Test Screenshot Comparision

I guess that only works if the branch isn't from fork, which doesn't work for external contributors.

[jeromelaban]

That's correct. Forks builds can't comment, unfortunately.

[Youssef1313]

I might look into a GitHub Actions approach that works for external contributors. @workgroupengineering feel free if you wanted to look into that as well, I won't be able to look soon, so you could do it before me if you want.

[jeromelaban]

At this point, the only way to handle this is to get a full build that generates all nuget packages in github actions, and there's no known link between GH actions and the Azure Devops build that are running.

[workgroupengineering]

GitHub Action can be trigger like this example.
We can pass PRid, baseVersion , CurrentVersion and BuildId as payload, through which we can build the url of the artifact to download and then perform the comparison.
