Question

我已经创建了一个具有以下配置的服务主机。

<?xml version="1.0"?>
<configuration>
  <system.serviceModel>
    <services>
      <service name="MathServiceLib.MathService" behaviorConfiguration="myMathServiceBehave">
        <host>
          <baseAddresses>
            <add baseAddress="http://localhost:9001/MathService"/>
            <add baseAddress="net.tcp://localhost:9002/MathService"/>
          </baseAddresses>
        </host>
        <endpoint address="http://localhost:9001/MathService" binding="basicHttpBinding" contract="MathServiceLib.IMathService"/>
        <endpoint address ="net.tcp://localhost:9002/MathService" binding ="netTcpBinding" contract="MathServiceLib.IMathService"/>
        <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/>
        <!--<endpoint address="mex" binding="mexTcpBinding" contract="IMetadataExchange"/>-->
      </service>
    </services>
    <behaviors>
      <serviceBehaviors>
        <behavior name="myMathServiceBehave">
          <!--<serviceMetadata httpGetEnabled="true"/>-->
        </behavior>
      </serviceBehaviors>
    </behaviors>
  </system.serviceModel>
</configuration>

我不想使用serviceMetadata httpGetEnabled =“true”属性，而是想使用MEX绑定来创建代理。

现在，当我使用

启动服务时

 svcHost = new ServiceHost(typeof(MathServiceLib.MathService));
 svcHost.Open();

我收到以下错误，请帮助。

在服务MathService实现的合同列表中找不到合同名称“IMetadataExchange”。将ServiceMetadataBehavior直接添加到配置文件或ServiceHost以启用对此合同的支持。

根据我的经验，您需要指定

<serviceMetadata httpGetEnabled="true"/>

如果你想使用

<endpoint address="mex" binding="mexTcpBinding" contract="IMetadataExchange"/>
