如何在不添加服务引用的情况下在.net核心中使用wcf？

[ServiceContract]
public interface IMyService
{
    [OperationContract]
    string GetData(int value);
}

public class MyService : IMyService
{
    public string GetData(int value)
    {
        return $"You entered: {value}";
    }
}

services.AddSingleton<IMyService, MyService>();

app.UseEndpoints(endpoints =>
{
    endpoints.MapService<IMyService>(new ServiceHostFactory(), "/MyService");
});

using (var client = new HttpClient())
{
    var content = new StringContent("{\"value\": 10}", Encoding.UTF8, "application/json");
    var response = await client.PostAsync("http://localhost:5000/MyService/GetData", content);
    var result = await response.Content.ReadAsStringAsync();
    Console.WriteLine(result);
}
