Not that I know of.

Hmmm, I love the effort you put in but I find it hard to pull this into the code base and a release because long term this is more difficult to support. People should move to .net6 or 7 anyways. Why would this be a good idea?

[ArchangelWTF]

Considering that MonoAndroid wont be End of Life until 2024 (Which means load of people will be still stuck in the migration of XF to MAUI) I'd say this is a perfect compromise where we can build for both somewhat painlessly.

I propose just supporting it for as long as ExoPlayerXamarin compiles with it (Meaning that the bindings dont get too complex for mono) I'll happily even maintain it since it wasn't too big of an issue to get it working in the way i've made it work above.

[ArchangelWTF]

Woops wasn't meant to press that, damn mobile phone.

@martijn00 I hope you'll consider accepting this PR. While it's true that MAUI is the future, there are good reasons for projects not to move to it just yet. Articles such as this one indicate that MAUI is still not quite ready for prime time. In the meantime, Xamarin users who aren't ready to make the switch would benefit from having the latest ExoPlayer releases available to them.

[martijn00]

I've been thinking about this. What about creating a new xamarin branch and releasing seperate nugets from there with a suffix -xamarin in the release title? Long term I wouldn't want to maintain the old stuff as it begins to break more and more.

[sschaub]

I can understand your concern about not wanting to maintain old stuff long term. Your idea of a separate branch and separate nugets would achieve that goal. But it would mean having to make updates to two separate branches in the short term. If you accept this PR, we would have a single branch to maintain in the short term. At some point in the future if maintenance of the Xamarin builds becomes problematic you could update the projects to be .net6 only, as they are at present, and perhaps consider making a Xamarin-only branch at that point if there is demand.

[martijn00]

Yes, but the update process will be done by Github Actions, so not a problem there. Also you can see in the bindings now that there need to be separate fixes for both. I rather have 1 point of truth and backport that to the Xamarin version.

Hi everyone. Best wishes for 2023 🎉 Is having a separate branch for the Xamarin version of ExoPlayerXamarin the way to go now?

[martijn00]

@ArchangelWTF @janwiebe-jump i've done some changes to support both from 1 codebase (hopefully), i'm not sure if all the metadata changes are now correct in the xamarin branch? Could you check and if possible make a PR?

When it works like i hope it would, i will enable: https://github.com/Baseflow/ExoPlayerXamarin/blob/develop/.github/workflows/dotnet.yml#L45

[janwiebe-jump]

LGTM! Thanks so much!

For some reason dotnet pack doesn't work: MSBUILD : error MSB1003: Specify a project or solution file. The current working directory does not contain a project or solution file.

[janwiebe-jump]

@martijn00 I ran into this earlier. Looks like the Xamarin projects cant be built with dotnet build / pack. building with MSBuild should generate the packages, which can then be pushed with a dotnet nuget push

[martijn00]

But i do build with msbuild. I want to use dotnet pack to re pack the already build nupkg
