Hi I have a good option for that you can create a self host service Please have a look this link https://www.c-sharpcorner.com/UploadFile/b1df45/web-api-self-hosting-using-windows-service/ Self hosted service has a hosting and port as well and it works as a service so you can use it as a monitoring purpose Thank you

Actually I have to do below program and I am trying to get some solution on how to do it. "Design and implement a solution in .net to monitor services. Design and implement in (.net) a service monitoring class. This monitor will be used to monitor the status of multiple services. A service is defined as a host/port combination. To check if a service is up, the monitor will establish a TCP connection to the host on the specified port. If a connection is established, the service is up, if the connection is refused, the service is not up."

You have to open that port from firewall Please follow this steps 1) To open a port, navigate to Start > Control Panel > System and Security. 2) Click Check firewall status. The Windows Firewall window appears. 3) Click Advanced settings. The Windows Firewall and Advanced Security screen appears. 4) Click Inbound Rules. 5) Click New Rule. The New inbound Rule Wizard appears. 6) Click Port 7) Click Next. The Protocol and Ports screen appears. 8) Click TCP. Then click Specific local ports. 9) Enter the port numbers to open. Ex. Which you had specified in your service 10) Click Next. The Action screen appears. Select Allow the connection. 11) Click Next. The Profile screen appears. 12) Click Next. The Name screen appears. Enter a name and description for the rule. 13) Click Finish. The rule is added. Thank you "Please mark as a answer if it's working for you"
