Question

以下代码抛出错误

名为＆＃39; service＆＃39;的子元素具有相同密钥的密钥已存在于相同的配置范围内。集合元素在同一配置范围内必须是唯一的（例如，相同的application.config文件）。重复键值：＆＃39; Marius.Marius_0_0_8＆＃39;。

现在显然有两个名为Marius.Marius_0_0_8的服务。但是，当我尝试将其中一个的名称更改为其他内容时，我会收到不同的错误。我假设这是因为名称必须与命名空间的名称相匹配。 .svc中的课程。

我累了，已经盯着这几个小时了。我究竟做错了什么？所有我真正想做的就是打开元数据，这样我就可以连接WCF测试客户端。

您正在尝试为Mex端点声明另一项服务。正确的方法是只有一个服务公开两个端点：真实服务端点和wsdl端点。

<services>
        <service name="Marius.Marius_0_0_8">
            <endpoint address="" behaviorConfiguration="Marius.MariusAspNetAjaxBehavior"
                binding="webHttpBinding" contract="Marius.Marius_0_0_8" />

        <endpoint name="mex"
              address="mex"
              binding="mexHttpBinding"
              contract="IMetadataExchange" />
      </service>

    </services>
