Failed to launch process for service - No such file or directory

Tye stopped working after update, which should not affect this.

I installed the latest preview of .NET 6 SDK Preview 7 x64 on my M1 Mac, and updated the Tye Global tools like so:

robert@RobertsMBPWork Commerce % dotnet tool update -g Microsoft.Tye --version "0.9.0-*" --add-source https://pkgs.dev.azure.com/dnceng/public/_packaging/dotnet5/nuget/v3/index.json

Tool 'microsoft.tye' was reinstalled with the latest stable version (version '0.9.0-alpha.21380.1').

My projects is targeting .NET 5:

I ran tye run:

I uninstalled both NET 6 SDK Preview 6 and 7, and it works again.

Doesn’t seem to play well with Tye at the moment.

I think this is because of the change to revert the AppHost as the default build output for MacOS. Project Reading derives the RunCommand from build metadata here, which should be the apphost executable, but on MacOS on .NET 6+ we do not create the AppHost due to signing issues. This means that the RunCommand is incorrect, and thus the service cannot be launched.
