I couldn't get the "Management Service Delegation" appear in IIS 10.0..17763.1 (running on Windows Server 2019), despite Web Platform Installer 5.1 showing that the following are already installed.
- Web Deploy 3.5 without bundled SQL support
- Web Deploy 3.6 without bundled SQL support
The Control panel / Programs and Features shows Web Deploy 4.0 in the list of installed apps!!
This was all to get the following error resolved, since the error persisted after following https://learn.microsoft.com/en-us/iis/install/installing-publishing-technologies/installing-and-configuring-web-deploy-on-iis-80-or-later
2> MSDeploy: Web deployment task failed. On the remote computer, make sure that WebDeploy is installed and that the required process ("Web Management service") is started. The error code is ERROR_DESTINATION_NOT_REACHABLE
2> MSDeploy: (404) Not Found.
2> MSDeploy: 1.
