Hi @JR ,
If all you're seeing is a
web.config on what I'm assuming is a Windows hosted app service, I'm thinking the issue is centered around a misconfigured yaml file. Have a look at Deploy an Azure Web App documentation. I'm guessing your Azure Web App task is deploying a package that doesn't contain your project assemblies which you can confirm by inspecting the artifacts in your pipeline. Inspect your pipeline logs for any build anomalies.
