Upgrade to Uno 3.x, minor control changes required
Switched to Uno 3.x. Using an Uno 2.x control in an Uno 3.x project can cause odd crash exceptions. Officially they say 3.x is soruce compat with 2.x so people shouldn't have an issue upgrading but clearly there can be minor differences.
Issues Resolved
fixes #375
API Changes
None
Platforms Affected
Core
Behavioral/Visual Changes
This moves users to uno 3.x so while there are no libvlcsharp changes there are some minor upgrade notes: https://github.com/unoplatform/uno/blob/master/doc/articles/migrating-from-previous-releases.md One tooltip had to migrate from content presenter to content control however I don't believe it should cause an issue. This is due to CP now allowing to have a content property bound to a non template item.
Before/After Screenshots
No UI changes.
Testing Procedure
Tested Android and UWP no ios device.

Using an Uno 2.x control in an Uno 3.x project can cause odd crash exceptions.
Does this mean we can only support 1 version of Uno within one package?
I had a heck of a time getting it to build (just the library in general). I even got some of these similar errors. Eventually to get it to build I was using android 9 and unloaded virtually all the projects other than UWP and android. After going through a slew of changes I tried reverting as much as I could to get it to still work.
I did find now I missed the IOS add so that should fix a few of the errors.
I also got the DisplayRequest errors, which I fixed by making it public rather than internal. As that was all libvlc code I couldn't figure out why that would be a new error. The assembly was properly marked as friend as well. I reverted it back to internal at the end and rebuilt and it was fine.
I am not sure if it just happens when there is not a successful build or if I am missing something.
Looking at the other errors it is likely relating to some of the templating child fetching that macos seems to catch but android doesn't oddly.
I will go through the theming and see. The View is no longer directly assigned as a child so may need to alter how they are grabbing the VideoView.
Otherwise I can see about installing the android 8 sdk to see if that is an issue, or it could also be IOS related (as the windows does the cross building).
In theory the VideoView.Android should only be compiled in for android and ios for ios right? As the cross compile errors seem odd. I could further gate them with platform #ifdefs but I didn't do so as I figured each was only used for its specific case.

Sorry to hear that. Have you followed our contribution guide and had a look at what the CI does and how it is setup? This can be helpful to have the solution building quicker.

Yes.

That settles it. We will moving to Uno 3, I guess.
The other option would be to create an uno 2.x legacy package or new uno 3 package, but in theory as the upgrade to uno 3 shouldn't be too big for users that may just be the logistically simpler option.
I will test the playback controls and further theme issues this weekend hopefully. From what I read that was the correct direction to be going for the sort of binding done.
As for build issues I am a big fan of docker and CI setup scripts and the failures I am sure are my own. A bit busy with work so only had so much time to see if I could fix this (just using libvlc for a side project).
I will try and look at it in more detail to see if there is anything I could think to add that might help other users (some of it is just opaque error messaging from the build system so not much to do about that). I think the solution itself is logistically complex with all the platforms so likely i will RTFM and just see if I can put some more warnings or help for what some errors may actually mean.

Yes, but I don't think it is worth the overhead with packaging, given how few users we seem to have on Uno.

So am I, but I use it for libvlc (https://code.videolan.org/videolan/docker-images), not libvlcsharp (though it has been planned https://code.videolan.org/videolan/LibVLCSharp/-/issues/91).

You need all the proper SDKs (Xamarin, netcore, desktop, etc.). Aside from this, the great MSBuildSdkExtras that we use for multi targeting should do the job (it is pulled automagically from the csproj).
Don't merge this in yet (if you ever would) still want to test some of the templating things. The error was due to not updating to Android 9 as Uno requires (this may also stop you from merging).
Don't merge this in yet (if you ever would) still want to test some of the templating things.
Ok. Yes, I intend to merge your contribution :-)
You can only test UWP and Android, right? Let me know and I'll check iOS. We also need to make sure the media element is still OK.
@mfkl @mitchcapper Can this be reopened and finalized please? It would be very beneficial to bring support for latest versions of Uno Platform. Happy to help if needed 👍
@MartinZikmund : Feel free to open your own PR to finish the job, I guess :)
@MartinZikmund I would be more than happy to help you look at this. We are going to need support for libvlc with Uno and Android later this year (Q3/Q4 timeline). I am more than happy to donate my time as well as some developers on my team to get this working.
Good to hear, feel free to join the Discord server if you need anything and to synchronize your work 😉
NOTE! This is not yet ready for merge the templating I am still testing and playing with. From my original PR here are the changes: *) Targetting the latest uno 3.7.3 *) Android version bumped up to 10 on all android projects. Android 10 is the minimum supported version for google now. Uno did the same (so 10 is minimum for current uno version). If we didn't want to do so the non-uno projects could target a lower android framework likely (let me know and I can revert to 81). *) The original debate item, ContentPresenter. What VS will now warn or error over is that binding to the content property of it like we were is likely not the right way to be using it (and can result in undefined behavior they warn on). I will still test and validate the change direction here is correct but either the ContentSource should be used or contentcontrol for actual binding from what I have found thus far. If It tests properly though I would assume changes are fine.
Android version bumped up to 10 on all android projects. Android 10 is the minimum supported version for google now. Uno did the same (so 10 is minimum for current uno version). If we didn't want to do so the non-uno projects could target a lower android framework likely (let me know and I can revert to 81).
Yes please, I'd like to stick to 8.1 for now if possible.
If anyone is still interested to take this up, much appreciated. Will allow us to remove a new needed workaround https://github.com/videolan/libvlcsharp/commit/00952b64c57e1e2cc65e9a2e4b417e797654a1ff
So I can't test this as I upgraded VS and ran into a bug, it seems the autobuild system may be hitting that same bug with the latest vs tools.

Ha! I saw you added that but as I was updating everything to 3.x I didn't even check what it was referencing. Clearly yes the same issue. As I can also repro locally I will make sure to use the latest uno builds and see if it still happens and post to them otherwise.
Updated my system to try to repro the failure from CI, but I can't repro locally, builds fine here.

Should that be in aWindow referenced or I would assume the android csproj that is failing.

I'd have guessed the AWindow bindings project. Though the implications of that workaround could be critical
A boolean property that controls whether the linker will insert GC.KeepAlive() invocations within binding projects to prevent premature object collection. Defaults to True for Release configuration builds.
