Hi!

When using PublishSingleFile=true there are no published dll files in \Temp\KuiperZone.PupNet\my-..-project\AppDir\Publish*.dll". This is a problem because Inno Setup throws error about this when running.

The problematic line is SetupBuilder.cs line 212

sb.AppendLine($"Source: \"{BuildAppBin}\\*.dll\"; DestDir: \"{{app}}\"; Flags: ignoreversion recursesubdirs createallsubdirs signonce;");

Example of this:
4_pupnet-innosetup (windows-latest).txt
github action run here

Possible solution:
After running dotnet publish but before running iscc check if there are dll files and if not remove that line from the iss file.
