nitpick: Could this property not be used directly?

I think I just replaced code from the previous implementation to make it cross-platform without changing the overall structure. We could inline it manually.

On the other hand, the method name is a bit more explicit. It's likely inlined anyway by the compiler, so it's just a matter of preference.

nitpick: This method seems to be unused. It would be great to integrate with RunNewApp somehow

It's used by the Avalonia plugin. It's needed for the designer.

@Jklawreszuk I have merged back master to this PR's branch.

It's mostly working but it would be nice to also support (un-)installing the Stride packages on Linux even if we can't fully use it there yet.

Did you want to contribute to it? The branch is on this repo, so feel free to push commits if you want.

I am sorry, but it took some time to review all the files.Overall, it looks great! A quite accurate implementation of the original Launcher. However, I have a few comments:

  • The ‘See release notes’ feature does not work - also an empty button is displayed. A hint that might be helpful - MarkdownScrollViewer.Markdown property is always null.
  • It would be nice to implement a custom title bar like in the original, but this can be done in a separate PR.

Other than that I didnt notice nothing unusual 😅

@Kryptos-FR Once the changes have been merged, I will try to adapt Launcher to Linux if necessary. But I think that installing/uninstalling packages works correctly, no?

I don't remember if it does work. I assume since it's restoring packages it should.

I guess we'll know soon.
