.net core下迎來了WCF——CoreWCF1.0，做了一個最初級的Demo，嘗嘗鮮。

首先在NuGet中引入下面兩個包

CoreWCF.Http?
CoreWCF.Primitives

本demo是用WCF實現(xiàn)一個ToDoList的幾個服務端方法，然后用創(chuàng)建客戶端服務調用，代碼如下：

WCF服務配置文件

{  "Urls": "http://localhost:5000;https://localhost:5001",  "Logging": {    "LogLevel": {      "Default": "Information",      "Microsoft.AspNetCore": "Warning"    }  },  "AllowedHosts": "*"}

WCF服務代碼：

using CoreWCF;using System.Diagnostics.CodeAnalysis;using System.Runtime.Serialization;using CoreWCF.Configuration;using CoreWCF.Description;
var builder = WebApplication.CreateBuilder(args);builder.WebHost.ConfigureKestrel((context, options) =>{    options.AllowSynchronousIO = true;});
builder.Services.AddServiceModelServices().AddServiceModelMetadata();builder.Services.AddSingleton();
var app = builder.Build();app.UseServiceModel(builder =>{    builder    .AddService(typeof(ToDoService))    .AddServiceEndpoint(new BasicHttpBinding(), "/ToDoService/basichttp")    .AddServiceEndpoint(new WSHttpBinding(SecurityMode.Transport), "/ToDoService/WSHttps");});
var serviceMetadataBehavior = app.Services.GetRequiredService();serviceMetadataBehavior.HttpGetEnabled = true;
app.Run();
[DataContract]public record Item{    [DataMember]    public string? Title { get; set; }    [DataMember]    [AllowNull]    public string? Description { get; set; }    [DataMember]    public DateTime CreateOn { get; set; }    [DataMember]    public bool IsComplete { get; set; } = false;}
[ServiceContract]public interface IToDoService{    [OperationContract]    bool Add(Item item);
    [OperationContract]    List GetList();
    [OperationContract]     bool Remove(string? title);}
public class ToDoService : IToDoService{    static List _list = new List();
    public bool Add(Item item)    {        item.CreateOn = DateTime.Now;        _list.Add(item);        return true;    }
    public List GetList() => _list;
    public bool Remove(string? title)    {        var item = _list.SingleOrDefault(s => s.Title == title);        if (item != null)        {            return _list.Remove(item);        }        else        {            return false;        }    }}

創(chuàng)建調用項目，右鍵項目“添加”-“服務引用”，選擇WCF Web Service，在啟動WCF服務的情況下,執(zhí)行下面圖示：

引入ToDoService后會多一個Connected Services的文件夾，剛才一頓操作的產物。因為在服務端Item類是record類型，自動生成會把它變成class，這里需要手動改成record，方便輸出時數(shù)據(jù)好看一些。

客戶端代碼，直接使用ToDoService：

using ToDoServiceReference;
var client = new ToDoServiceClient(ToDoServiceClient.EndpointConfiguration.WSHttpBinding_IToDoService, "https://localhost:5001/ToDoService/WSHttps");
while (true){    Console.WriteLine("1、Add ToDo  2、Get ToDoList 3、Remove ToDo");    switch (Console.ReadLine())    {        case "1":            var addResult = await client.AddAsync(new AddRequest            {                item = new Item { Title = "title_" + DateTime.Now.ToString("yyyyMMddHHmmss"), Description = "description_" + DateTime.Now.ToString("yyyyMMddHHmmssffffff") }            });            Console.WriteLine(addResult.AddResult);            break;        case "2":            var listResult = await client.GetListAsync(new GetListRequest { });            foreach (var item in listResult.GetListResult)            {                Console.WriteLine(item);            }            break;        case "3":            var delResult = await client.RemoveAsync(new RemoveRequest            {                title = Console.ReadLine()            });            Console.WriteLine(delResult.RemoveResult);            break;        default:            Console.WriteLine("input error");            break;    }}

結果：
