This repo contains scripts to update your Azure Virtual Machine Scale Set model to have dotnet core runtime installed, using VMSS custom script extensions and the dotnet-install script: https://github.com/dotnet/docs/blob/master/docs/core/tools/dotnet-install-script.md

The custom script extension for VMSS can download a script and execute it on a VMSS. The Install-DotnetRuntimeVMSS.ps1 script is the script you run to update the VMSS model with this extension. The Install-DotnetVMSS.ps1 script is the script that's downloaded to the VMSS node and executed to do the install. The Install-DotnetVMSS.ps1 also adds the install directory to the system path.

1. In the Install-DotnetRuntimeVMSS.ps1 file, you can add parameters to the $commandToExecute variable, which will control the version, release channel and install directory for dotnet. Use this for reference: https://github.com/dotnet/docs/blob/master/docs/core/tools/dotnet-install-script.md.

2. Update the VMSS model by running the Install-DotnetRuntimeVMSS.ps1 script.
