## Usage

### H.Firewall

Forbids for 15 seconds everything except LAN/DNS/Localhost requests and Chrome applications.  

NOTE: To use this code in your application, you must either run it as an administrator or 

run it through a service talking to it via IPC (eg [H.Pipes](https://github.com/HavenDV/H.Pipes)).

Else you will get the following error: `0x8032000D. The call must be made from within an explicit transaction.`

```cs

using var firewall = new FirewallBuilder()

    .Block()

    .All()

    .Allow()

    .Localhost()

    .DomainNameSystem()

    .LocalAreaNetwork()

    .Application(@"C:\Users\haven\AppData\Local\Google\Chrome\Application\chrome.exe")

    .Build();

await Task.Delay(TimeSpan.FromSeconds(15));

```

H.Firewall uses [WFP](https://docs.microsoft.com/en-us/windows/win32/fwp/windows-filtering-platform-start-page) calls internally, 

you can learn more about this.
