Deployment @meliss_houghton

Slide 12

Framework-dependent

Install .NET on the device curl -sSL https://dot.net/v1/dotnet-install.sh | bash /dev/stdin —channel Current # Publish the app with Deployment mode = Framework-dependent and Target runtime = Portable dotnet publish # Copy the files from the computer to the device scp -r /publish-location/* pi@raspberrypi:/home/pi/deployment-location/ # Run the app on the device dotnet HelloWorld.dll

Self-contained

Publish the app with Deployment mode = Self-contained and Target runtime = linux-arm dotnet publish -r linux-arm # Copy the files from the computer to the device scp -r /publish-location/* pi@raspberrypi:/home/pi/deployment-location/ # Run the app on the device chmod +x HelloWorld

./HelloWorld @meliss_houghton
