A .NET wrapper for the Win32 HTTP Server URL ACL APIs found in Http.h. This library can be considered as a programmatic alternative to Windows command line tools netsh http show|add|delete urlacl.
This library wraps around native methods HttpSetServiceConfiguration, HttpDeleteServiceConfiguration and HttpQueryServiceConfiguration.

}This library only does the URL ACL. The below libraries may be used for the firewall and certificate.
The WindowsFirewallHelper NuGet package can be used to add exceptions to the Windows firewall. The below example shows how to use it to add a firewall rule for port 80. Because it is HTTP.SYS (not your application) that is actually listening the application is set to "System".
var profiles = FirewallProfiles.Domain | FirewallProfiles.Private | FirewallProfiles.Public;
var rule = FirewallManager.Instance.CreateApplicationRule(profiles, "Test rule for HTTP.SYS", FirewallAction.Allow, "System", FirewallProtocol.TCP);
rule.LocalPorts = new ushort[] { 80 };
FirewallManager.Instance.Rules.Add(rule);The SslCertBinding.Net NuGet package can be used to bind a certificate if you want to use HTTPS.
