如何删除应用服务的孤立托管标识

Question

不知何故，我得到了一个托管标识，其主应用程序早已被删除。如何删除它？请帮忙

我可以运行以下命令来查找 MSI 对象（注意 $appServiceName appService 不再存在）

PS C:\src\S\aspbuild-arm\azure\scripts> az ad sp list --display-name $appServiceName

或者我可以在“企业应用程序”刀片下搜索 MSI，如果我单击它并转到其属性，并尝试导航到其应用程序，我会收到“找不到资源”。附上截图。

即使我尝试从命令行删除，我也做不到。

更新：运行 az ad sp delete 也会出现错误“权限不足，无法完成操作”。我有全局管理员并怀疑它是因为它是一个 MSI 并且应该完全由 Azure 管理
