I've successfully built my code on Azure Dev Ops by modifying the pipeline YAML file, but I have been unable to successfully deploy the artifact to my IIS Server. The only way to create a deployment is by using its unpleasant UI.
I've read that by turning on a multi-pipelines preview feature, you can view and edit the YAML file. Unfortunately, it doesn't work. You can edit the build scripts, but not the release ones. I tried to add deployment tasks in the main pipeline YAML file, but it neither executes or shows up in the releases section.
