Deploying NetFwTypeLib to manage the Windows Firewall

Question

My Windows service needs to create/remove certain rules from the Windows firewall. For this I interface with NetFwTypeLib in \\system32\\hn

Answer 1

NetFwTypeLib object doesn't reside in hnetcfg.dll library on Windows 7 Ultimate. Rather, it resides in FirewallAPI.dll at %system32%\FirewallAPI.dll (eg c:\windows\system32\FirewallAPI.dll).

using NetFwTypeLib; // Add reference %SystemRoot%\System32\FirewallAPI.dll
