WCF自托管服务可以有初始化逻辑吗？

using System;
using System.ServiceModel;

namespace MyWcfService
{
    public class MyServiceHost : ServiceHost
    {
        public MyServiceHost(Type serviceType, params Uri[] baseAddresses) : base(serviceType, baseAddresses)
        {
        }

        protected override void OnOpening()
        {
            // 执行初始化逻辑
            Initialize();

            base.OnOpening();
        }

        private void Initialize()
        {
            // 执行初始化操作，例如数据库连接的初始化、配置文件的读取等
            // ...
        }
    }

    // 定义WCF服务契约
    [ServiceContract]
    public interface IMyService
    {
        [OperationContract]
        string GetData(int value);
    }

    // 实现WCF服务契约
    public class MyService : IMyService
    {
        public string GetData(int value)
        {
            return $"You entered: {value}";
        }
    }
}
