A simple and intuitive .NET implementation of the [Chrome Native Messaging](https://developer.chrome.com/apps/nativeMessaging) protocol.

* Easy to use

* No JSON parsing or dependencies

* .NET Standard & platform independent

* Testable through abstractions

* Async support

* Separate installer library

* NuGet packages available

### Chrome.NativeMessaging

Creating a native messaging host is dead simple: just call `StartListening` and pass in your message handler as a `Func`:

```C#

var host = new NativeMessagingHost();

host.StartListening(jsonMessage =>

{

    var response = DoSomethingAndCreateResponse(jsonMessage);

    return response;

});

```

### Chrome.NativeMessaging.Installer

Use this package to install your native messaging host. Just create a manifest and let the library do the rest:

```C#

var manifest = new NativeMessagingHostManifest

{

    Name = "com.my_company.my_application",

    Description = "My Application",

    Path = @"C:\Program Files\My Application\chrome_native_messaging_host.exe",

    AllowedOrigins = new []

    {

        "knldjmfmopnpolahpmmgbagdohdnhkik"

    }

};

// System.IO.Abstractions

var fs = new FileSystem();

var installer = NativeMessagingHostInstallerFactory.CreateInstaller(fs);

installer.Install(manifest);

```
