Hey Matt! We don't support preview releases.

We'll release .NET 10 support when it GAs next month.

[mattleibow]

One issue is that since this is used in the maui templates, the GA templates will be using the older versions and right now has error during restore.

Is there a way to maybe get some stable builds released so that maui can use that in the maui stable release?

I know this makes things more complex, but it is sort of chicken and egg. We need stable, but you need stable, so we must go to the stables together.

I am currently disabling warnings and working around errors in the GA templates: dotnet/maui#32251

[TheCodeTraveler]

Got it.

Ok, I'll cherry-pick the commit from our .NET 10 PR where we remove the NuGet restriction on Microsoft.Maui.Controls v10.x.x and I'll squeeze it into our upcoming release.

I do recommend updating the CommunityToolkit.Maui dependency in the .NET 10 templates to CommunityToolkit.Maui v13.0.0 which is the version that will support .NET 10, because I can't promise that CommunityToolkit.Maui v12.x is compatible with .NET 10.

Ah ok. Thanks for that. We should better communicate things. Please feel free to open an issue saying "up the templates now peeps" if you see we are not doing that.

If there is a preview version to test with during the RC stages, then we can also make sure our testing happens on the MCT as well as all of the Syncfusion controls work as expected.

[TheCodeTraveler]

No worries Matt! We've never added a mechanism in our release pipeline for preview releases.

This will be included in the next release, CommunityToolkit.Maui.12.3.0.
