Create a firewall rule to open a port for each application programmatically in C #

Question

I need to open a specific port for my application.

I tried using the rule INetFwAuthorizedApplicationfor each application for all ports.

fwMgr.LocalPolicy.CurrentProfile.AuthorizedApplications.Add(app)

Alternatively, open one port for all applications using INetFwOpenPort.

firewallManager.LocalPolicy.CurrentProfile.GloballyOpenPorts.Add(port)

Is there a way to programmatically open only one port for each application programmatically? I can do this manually through the firewall settings.
