Fails with .NET 10 rc2

When running dotnet publish with .NET 10 rc2, you get an error

Restore complete (0.7s)
    info NETSDK1057: You are using a preview version of .NET. See: https://aka.ms/dotnet-support-policy

This was working with .NET rc1, so something must have changed between rc1 and rc2? Maybe rc2 requires an entrypoint again?

I was able to get it to compile on .NET 10 rc2 by switching the OutputType to exe and just adding an empty public static void Main.
