Executable from `dotnet publish` for Apple Silicon is not working. .net 6 preview 1.

[iamphi]

The executable from dotnet publish --self-contained -r osx-arm64 does not run as expected. It fails with a kill signal like: zsh: killed

Test script:

mkdir helloworld
cd helloworld 
dotnet new console

echo "### Testing dotnet run"
dotnet run

echo "### Testing intel publish"
dotnet publish --self-contained -r osx-x64 -o intel
lipo -info intel/helloworld
./intel/helloworld                                                     

echo "### Testing arm64 publish"
dotnet publish --self-contained -r osx-arm64 -o arm64
lipo -info arm64/helloworld
./arm64/helloworld 

My output:

The template "Console Application" was created successfully.

I hit this as well and found that you need to sign the binary.

codesign -s _identity_ arm64/helloworld

[iamphi]

@bholmes Thank you.
I was able to sign without an identity with:
codesign -s - arm64/helloworld
and helloworld was able to run on my computer. I zipped up arm64 and gave it to my colleague and they were able to run it too.

From "macOS Big Sur 11.0.1 Universal Apps Release Notes"
https://developer.apple.com/documentation/macos-release-notes/macos-big-sur-11_0_1-universal-apps-release-notes

New in macOS 11 on Macs with Apple silicon, and starting in macOS Big Sur 11 beta 6, the operating system enforces that any executable must be signed before it’s allowed to run. There isn’t a specific identity requirement for this signature: a simple ad-hoc signature is sufficient. This new behavior doesn’t change the long-established policy that our users and developers can run arbitrary code on their Macs, and is designed to simplify the execution policies on Macs with Apple silicon and enable the system to better detect code modifications. This new policy doesn’t apply to translated x86 binaries running under Rosetta 2, nor does it apply to macOS 11 running on Intel-based platforms.

Moving to host area since the published host needs signing. Believe there is a separate issue tracking that.
