I am using Azure DevOps to deploy a .Net Web Application. I wanted to update to the new Os Family which is based on Windows 2019 so i can Update my projects to .net framework version 4.7.2 as seen here. I have updated my cloud service configuration '.cscfg' file to osFamily="6" but when i try to deploy the app even though the Build succeeds i get this error when i reach the Release step in Azure pipeline:
The OS family 6 you are trying to deploy is not supported by the SDK package. The SDK package supported OS families:3,4,5,1,2,98,97. Please try to deploy to a different operating system. To do this specify a different osFamily and/or osVersion in your .cscfg file.
I am using the Hosted VS2017 agent.
According to the error information it indicates that the OS family 6 are not supported by Hosted VS2017 agent.
Based on the link you mentioned that Compatible SDK versions should be Version 2.9.6+.
So my workaround is that you could use the Self-host agent with latest Azure SDK installed. We could download the latest Azure SDK from this link.
or you could have a try to install the Azure SDK on the Host 2017 agent (without test)
You also could give your feedback to Azure Devops team.
