Please log an issue at Azure-Pipelines-YAML. Over there we discuss YAML templates, samples for Azure Pipelines, and designs for upcoming YAML features. Also a place for the community to share best practices, ideas, and so on. File suggestions and issues here if they're specific to YAML pipelines.
Log an issue at Azure-Pipelines-Tasks. It contains all of the in-box tasks we ship with Azure-Pipelines/VSTS/TFS. If you're having issues with tasks in Build/Release jobs (e.g. unreasonable task failure) please log an issue there.
Log an issue at Hosted Agent Image Repository. It contains the VM image used in the Azure Pipelines Hosted Agent Pool. If you're having Build/Release failures that seems like they are related to software installed on the Hosted Agent (e.g. the dotnet SDK is missing or the Azure SDK is not on the latest version) please log an issue there.
