.NET 10 regression in publishing extra files

I am using Visual Studio to deploy ASP.NET Core website to IIS, presumably using MSDeploy. When targeting .NET 8, this causes files to be deployed to the server:

```xml

PreserveNewest

```

However, when I change the project to target .NET 10, these files do not get deployed. I tried `CopyToPublishDirectory`, I tried `Content`, I tried `Update`, but I just cannot figure out how to get them deployed. I did not see any breaking change notes in the .NET 10 release notes either. What trick am I missing?
