在.NET框架应用程序中使用WCF

using System;
using System.ServiceModel;

[ServiceContract]
public interface IHelloWorldService
{
    [OperationContract]
    string SayHello(string name);
}

public class HelloWorldService : IHelloWorldService
{
    public string SayHello(string name)
    {
        return $"Hello, {name}!";
    }
}

class Program
{
    static void Main(string[] args)
    {
        using (ServiceHost host = new ServiceHost(typeof(HelloWorldService)))
        {
            host.Open();
            Console.WriteLine("Service is ready.");
            Console.ReadLine();
            host.Close();
        }
    }
}

using System;
using System.ServiceModel;

class Program
{
    static void Main(string[] args)
    {
        using (ChannelFactory<IHelloWorldService> factory = new ChannelFactory<IHelloWorldService>("BasicHttpBinding_IHelloWorldService"))
        {
            IHelloWorldService client = factory.CreateChannel();
            string result = client.SayHello("World");
            Console.WriteLine(result);
        }
    }
}
