Use Get-NetTCPConnection

Get-NetTCPConnection | where Localport -eq 5000 | select Localport,OwningProcess

Localport OwningProcess

If you are using PowerShell Core v6 and above use Test-Connection

>Test-Connection localhost -TcpPort 80
True

Following the other answers, once you run Get-NetTCPConnection | where Localport -eq 5000 | select Localport,OwningProcess you can check which process/application is using the port by running Get-Process

Get-Process -Id <OwningProcess>
