ubuntu-latest pipelines will use ubuntu-24.04 soon. For more details, see https://github.com/actions/runner-images/issues/10636

Nullability of reference types in return type of 'T? FromObservableSignal<T>.Value.get' doesn't match implicitly implemented member 'T IReadOnlySignal<T>.Value.get' (possibly because of nullability attributes).

Nullability of reference types in return type of 'T? FromObservableSignal<T>.UntrackedValue.get' doesn't match implicitly implemented member 'T IReadOnlySignal<T>.UntrackedValue.get' (possibly because of nullability attributes).

Nullability of reference types in type of parameter 'observer' of 'IDisposable FromObservableSignal<T>.Subscribe(IObserver<T?> observer)' doesn't match implicitly implemented member 'IDisposable IObservable<T>.Subscribe(IObserver<T> observer)'.

Test methods should not call ConfigureAwait(ConfigureAwaitOptions.ForceYielding), as it may bypass parallelization limits. Ensure ConfigureAwaitOptions.ContinueOnCapturedContext in the flags. (https://xunit.net/xunit.analyzers/rules/xUnit1030)

Test methods should not use blocking task operations, as they can cause deadlocks. Use an async test method and await instead. (https://xunit.net/xunit.analyzers/rules/xUnit1031)
