Hello,
Yes, according to the Maui .net 9 documentation, you need to specify the version of Microsoft.Maui.Controls to .net 9.
If your app's project file references a .NET 8 version of the Microsoft.Maui.Controls NuGet package, either directly or through the $(MauiVersion) build property, update this to a .NET 9 version.
Best Regards,
Alec Liu.
