HyperV WCF Transport

Provides a binding and transport to allow HyperV communication across VM boundaries without network connections using Hyper-V Sockets.

Example Server running on a guest VM:

[ServiceBehavior(InstanceContextMode = InstanceContextMode.Single, ConcurrencyMode = ConcurrencyMode.Multiple, UseSynchronizationContext = false)]
class SampleServer : IServer
{
    public string DoThing(string foo)
    {
        Console.WriteLine($"Received {foo}");
        return $"Hello {foo}";
    }
}

class Program
{
    static void Main(string[] args)
    {
        var sh = new ServiceHost(new SampleServer());
        var binding = new HyperVNetBinding();
        sh.AddServiceEndpoint(typeof(IServer), binding, "hypervnb://00000000-0000-0000-0000-000000000000/C7240163-6E2B-4466-9E41-FF74E7F0DE47");
        sh.Open();
        Console.ReadLine();
        sh.Close();
    }
}

Example Client running on the Hypervisor:

class Program
{
    static void Main(string[] args)
    {
        var client = new ServerClient(new EndpointAddress("hypervnb://642d4719-f5d7-477d-9ca3-2c46c280052d/C7240163-6E2B-4466-9E41-FF74E7F0DE47"));
        client.Open();
        Console.WriteLine(client.DoThing("bar"));
        Console.WriteLine(client.DoThing(Console.ReadLine()));
        client.Close();
        Console.ReadLine();
    }
}

class ServerClient : ClientBase<IServer>, IServer
{
    public ServerClient(EndpointAddress addy)
        : base(new HyperVNetBinding(), addy)
    {
    }

    public string DoThing(string foo) => Channel.DoThing(foo);
}

Notes:

• Replace C7240163-6E2B-4466-9E41-FF74E7F0DE47 with the service ID you register in the registry (see Example Hypervisor Service Registration.reg). When developing a new app, the service ID should be unique and generated specifically for that application.
  • Register your service ID in the hypervisor registry
  • Enable "Guest Services" in the VM settings under "Integration Services"
• Replace 642d4719-f5d7-477d-9ca3-2c46c280052d with the ID of the VM to which you want to connect. The VM ID can be found with Powershell using Get-VM.
