title: Could not delete any project in an on premise Azure Devops
body: <p>According to <a href="https://docs.microsoft.com/en-us/azure/devops/organizations/projects/delete-project?view=azure-devops" rel="nofollow noreferrer">Microsoft's document</a>, a project could be deleted from the Overview menu of Project settings. but in my own on premise Azure Devops 2019, there is no Delete button at all.<br>
