Fails with .NET 10 rc2: Root assembly 'qr' does not have entry point.

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.

Thank you for spotting it. The issue can be workarounded by installing wasm-tools workload. I have opened a fix it dotnet/runtime#122607
