I am not a big fan of supporting multiple versions at the same time because in the past I have found this can cause obscure bugs which at some point took a significant part of the time to diagnose. It also results in more non-deterministic build errors. Now supporting multiple versions may not be very problematic in all scenarios, so we should consider supporting 10, but we should weigh the pros and cons. For MAUI I introduced a separate nuget package to support MAUI 8. Not sure if that is the best option, but at least it makes diagnosing problems a bit easier.

Good point, initially I only want to target here the samples and unit tests to .NET 10 Frameworks, without additional Targets, To see if it works seemlessly or improvements need to be done.
