.net WCF-是否可以远程创建对象？怎样？

当带有某个WCF服务的主机进程正在运行时-一切正常。 但当托管进程未运行时，WCF无法创建对象并使用它

换句话说，我有一个名为“ScrnSrvcR2.exe”的进程，它承载着通过WCF公开的“ScreensApi”对象。 所以，当“ScrnSrvcR2.exe”进程运行WCF时，客户端可以连接并使用“ScreensApi”对象。但当“ScrnSrvcR2.exe”进程未运行时-客户端无法连接

问题是，是否可以通过第一个创建“ScreensApi”对象的请求使远程系统（也包括作为远程系统特殊情况的localhost）自动启动该托管进程

因此，在这种情况下，我希望从WCF获得某种DCOM风格的功能，远程系统可以调用CreateRemoteComObject函数，并且对象宿主进程将自动启动，并提供对象的实例

有可能用WCF来做吗？ 怎么做

下面是我用来创建WCF对象的一段代码，仅供参考：

// this code works fine when "ScrnSrvcR2.exe" is running
protected void InitializeScreens()
{
    string endPointAddr = null;
    string transport = "net.tcp://";
    string hostAddress = "localhost";
    string servicePath = "ScreensApi";

    // [... optional reading of transport, hostAddress, servicePath values skipped... ]

    if (string.IsNullOrEmpty(endPointAddr))
        endPointAddr = transport + hostAddress + "/" + servicePath;

    System.ServiceModel.Channels.Binding bnd = null;
    NetTcpBinding tcpBinding = new NetTcpBinding();
    bnd = tcpBinding;
    tcpBinding.Name = "epNetTcp"; // this name is defined in config file

    EndpointAddress endpointAddress = new EndpointAddress(endPointAddr);

    bool isGoodProxy = false;
    try
    {
        try
        {
            this.ScreensProxy = new ScreensApiClient(bnd, endpointAddress);

            string un = null, pw = null;
            // [... optional reading of login/password skipped...]
            if (!string.IsNullOrEmpty(un) && !string.IsNullOrEmpty(pw))
            {
                ToLogger(TraceLevel.Verbose, string.Format("Station[ {0} ].Screens => Use credentials: {1}, {2}", this.Name, un, pw));
                this.ScreensProxy.ClientCredentials.UserName.UserName = un;
                this.ScreensProxy.ClientCredentials.UserName.Password = pw;
            }

            un = null; pw = null;
            // [... optional reading of login/password skipped...]
            if (!string.IsNullOrEmpty(un) && !string.IsNullOrEmpty(pw))
            {
                ToLogger(TraceLevel.Verbose, string.Format("Station[ {0} ].Screens => Use Windows-credentials: {1}, {2}", this.Name, un, pw));
                this.ScreensProxy.ClientCredentials.Windows.ClientCredential.UserName = un;
                this.ScreensProxy.ClientCredentials.Windows.ClientCredential.Password = pw;
            }

            this.ScreensProxy.Open();
            this.ScreensProxy.Ping(); // note: Ping() is a method of ScreensApi object, just to check if it is alive
            this.ScreensStationDescriptor = this.ScreensProxy.CreateStationDescriptor(this.Owner.Name, this.Name, CommonUtils.HostInfoStamp());
            this.ScreensProxy.InitializeStation(this.ScreensStationDescriptor);
            this.ScreensRuntimeContext = this.ScreensProxy.GetStationContext(this.ScreensStationDescriptor);

            isGoodProxy = true;
        }
        catch (Exception exc)
        {
            ToLogger(TraceLevel.Error, string.Format("Station[ {0} ].Screens -> {1}\n at {2}", this.Name, ErrorUtils.FormatErrorMsg(exc), exc.StackTrace));
            throw;
        }
    }
    finally
    {
        if (!isGoodProxy)
        {
            this.ScreensProxy = null;
            this.ScreensStationDescriptor = null;
            this.ScreensRuntimeContext = null;
            ToLogger(TraceLevel.Warning, string.Format("Station[ {0} ].Screens -> Remove ScreensProxy object ref as invalid!", this.Name));
        }
    }
}

我可能需要在代码中添加什么，使其自动启动WCF对象托管过程

提前谢谢。

您考虑过在IIS中托管吗？WCF不是远程对象管理器或类似的东西-它只是一个基于XML可序列化数据OK的消息传递系统。您能推荐一些.NET域中的远程对象管理器吗？
