我目前正在设置一个wcf SOAP Web服务，该服务使用OAuth v1（DotNetOpenAuth）来自动化用户。我通过IIS7在远程服务器上托管该站点。最近我成功地让网络服务返回用户的时间表，这就像一个魅力。
但是，现在我还需要能够通过此Web服务检索用户的测试结果。为此，我的Web服务调用另一个，现有的Web服务来检索结果，然后对它们进行格式化并将它们返回给用户。
我首先创建了一个测试web服务来完成这项工作，它完美地工作 - 我在SoapUI中加载我的Web服务的wsdl文件，并返回所需的结果（通过调用其他web服务）。
但是，在将方法实现到实际项目中时，它会失败。显然，由web.config文件中的元素引起了一个hickup;
<configuration>
...
<applicationSettings>
<OAuthServiceProvider.Properties.Settings>
<setting name="OAuthServiceProvider_Zuyd_OsirisService" serializeAs="String">
<value>http://.../OsirisServices-OsirisServices/OsirisServicePort</value>
</setting>
</OAuthServiceProvider.Properties.Settings>
</applicationSettings>
</configuration>
使用...作为IP地址和端口号。当我包含这段代码（通过添加Web引用自动生成）时，每当我尝试访问Web引用时，我都会收到错误消息“远程服务器返回错误：（500）内部服务器错误”网站上的其他文件，就此而言）。如果我不包含它，那么我可以访问网站上的文件就好了，但是，好吧，那么我显然无法调用第二个Web服务。
我对这段代码做错了吗？或者还有其他我缺少的东西？
我在下面提供了完整的错误文字;

编辑：我应该注意，在我的测试网络服务（有效的网络服务）中，添加网络参考会导致以下代码块自动生成;
<appSettings>
<add key="Zuyd.OsirisService" value="http://.../OsirisServices-OsirisServices/OsirisServicePort"/>
</appSettings>
我不知道为什么元素出现在测试Web服务中，而元素出现在实际的Web服务中。在这两种情况下，我只需右键单击项目名称并选择“添加Web引用”。
另一个编辑：正如我在第二篇评论中所解释的那样，appSettings元素与它无关，它是web.config中缺少的另一个元素。将该元素添加到我的web.config后，我收到以下错误
