流服务 - netTCPBinding - 服务构建,安装,但不会启动

标签: wcf stream nettcpbinding servicehost

我有一个使用netTcpBinding,transferMode =“Streamed”的WCF服务,并通过Windows Process Activation Services方法通过installutil安装。该服务构建和安装就好了。我在包含文件夹上拥有NETWORK SERVICES的所有正确权限,以访问.exe文件。我的问题是我一直收到错误:

“本地计算机上的服务[ServiceName]已启动然后停止。如果某些服务未被其他服务或程序使用,则会自动停止。”

奇怪的是主机安装程序代码与我运行的缓冲服务相同。在流服务中,我在需要时考虑了传递流和消息。我被卡住了。我似乎无法找出为什么这项服务不会站起来。我检查了端口,它们是开放的(没有冲突)。有没有人对'Streamed'netTcp服务没有启动提出建议?

以下是App.Config的样子:

<system.serviceModel>
    <!--### Service Endpoints: ###-->
    <!--Define Bindings-->
    <bindings>
      <netTcpBinding>
        <binding name="netTcpStreamedBinding" closeTimeout="00:01:00" openTimeout="00:01:00"
            receiveTimeout="00:20:00" sendTimeout="00:10:00"
            transferMode="Streamed" maxBufferPoolSize="104857600"
            maxReceivedMessageSize="1073741824" maxBufferSize="262144">

    <!-- Commented below out to match service that worked to see if this was error - It is not the problem (still no start)
        <security mode="Transport">
            <transport clientCredentialType="Windows" protectionLevel="EncryptAndSign" />
            <message clientCredentialType="Windows" />
          </security>-->

        </binding>
      </netTcpBinding>
    </bindings>

      <!--Streamer Service-->
    <services>
      <service name="MyServiceLib.FileStreamer">
        <endpoint address="" binding="netTcpBinding" bindingConfiguration="netTcpStreamedBinding" contract="MyServiceLib.IFileStreamer">
          <identity>
            <dns value="localhost"/>
          </identity>
        </endpoint>
        <host>
          <baseAddresses>
            <add baseAddress="net.tcp://localhost:.../MyStreamerService"/>
          </baseAddresses>
        </host>
      </service>
    </services>

          <!-- To avoid disclosing metadata information,

看来,即使使用Visual Studio 2012,我遇到了这个错误(最初发布于VS 2010):

Bug 571961 (marked as closed) - "Unable to Copy File"

此错误抛出“无法复制文件...因为它正被另一个进程使用”错误。解决方法对我有用 - 清理项目。关闭Visual Studio。重新打开VS.建立项目。按照这个过程,我可以建立我的服务。

此外,在重复构建时,部分问题是需要在构建之前“停止”服务管理器中的服务。一定不要忘记这一点。
