@brminnick should I include generated file in the PR?

[TheCodeTraveler]

Nope, we'll automatically generate the files branched off of each Release tag

@jfversluis @brminnick @pictos Is there any ETA on this pr?

[TheCodeTraveler]

Yup!

Our plan is to release Xamarin.CommunityToolkit v1.3.0 in the next few days.

Once that Release tag has been created, I'll create Xamarin.CommunityToolkit.MauiCompat v1.3.0 using the updated steps in this PR. If everything works, we'll merge the PR!

[maxkoshevoi]

@brminnick Sounds great! Could you please also address #1645 in the 1.3.0 MauiCompat release?
I wanted to create a PR myself, but current MauiCompat code fails to build with latest MAUI preview, so I'm unable to validate that adding .net6 won't break the build.

[TheCodeTraveler]

Of course!

@maxkoshevoi Unfortunately, it is not included in this PR. Adding net6.0 cause a lot of build issues and require manual changes.
In most cases we need to wrap shared code with #if !Android && !iOS.

I know. I meant there should be another PR after this one that addresses #1645

Adding net6.0 cause a lot of build issues and require manual changes. In most cases we need to wrap shared code with #if !Android && !iOS.

That's strange. XCT supported platform-agnistic build targets (line .netstandard), so in theory it also should be able to support .net6.0. In any case, users should be able to include MauiCompat toolkit in pratform-agnostic projects, since they were able to do it with XCT (and are able to do it with MauiToolkit, and Maui itself).

Thanks @VladislavAntonyuk!! 🙌

@brminnick could you please reapprove it?
