　　================================================================

当maxConnections > 10时，服务会抛出异常EndpointNotFoundException。

解决方法：修改mexTcpBinding的端口，不要与baseAddress的端口一样。比如：

<service name="WcfServiceLibrary1.Service1" behaviorConfiguration="WcfBehavior">
        <endpoint address="" binding="netTcpBinding" bindingConfiguration="netTcpBindingConfig" contract="WcfServiceLibrary1.IService1" />
        <endpoint address="net.tcp://localhost:7733/Service1/mex" binding="mexTcpBinding" name="MEX" contract="IMetadataExchange" />
        <host>
          <baseAddresses>
            <add baseAddress="net.tcp://localhost:8733/Service1" />
          </baseAddresses>
        </host>
</service>
