WebService 错误：无法加载协定为xxx的终结点配置部分，因为找到

当在vs 2010中添加服务引用后，如果“更新”服务引用，或“删除”该服务引用后再次加入后，在运行时会出现此错误。这是因为在“更新/ 删除”服务引用时，app.config文件并不会自动修改，在“更新”或再次“加入”后，会生成两个同样的“endpoint”，需要手工删除掉原有 的才能正常运行。 第一次加入后的app.config ? <client> ??????????? <endpoint address="http://localhost/WSTest/TestDalWS.asmx" binding="basicHttpBinding" ??????????????? bindingConfiguration="TestDalWSSoap6" contract="WSServer.TestDalWSSoap" ??????????????? name="TestDalWSSoap6" /> ?? </client> 对应的 <bing> 也只有一个。 ?<bindings> ??????????? <basicHttpBinding> ??????????????? <binding name="TestDalWSSoap6" closeTimeout="00:01:00" openTimeout="00:01:00" ??????????????????? receiveTimeout="00:10:00" sendTimeout="00:01:00" allowCookies="false" ??????????????????? bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard" ??????????????????? maxBufferSize="65536" maxBufferPoolSize="524288" maxReceivedMessageSize="65536" ??????????????????? messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered" ??????????????????? useDefaultWebProxy="true"> ??????????????????? <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384" ??????????????????????? maxBytesPerRead="4096" maxNameTableCharCount="16384" /> ??????????????????? <security mode="None"> ??????????????????????? <transport clientCredentialType="None" proxyCredentialType="None" ??????????????????????????? realm=""> ??????????????????????????? <extendedProtectionPolicy policyEnforcement="Never" /> ??????????????????????? </transport> ??????????????????????? <message clientCredentialType="UserName" algorithmSuite="Default" /> ??????????????????? </security> ??????????????? </binding> ??????????? </basicHttpBinding> ??????? </bindings> ? 在“更新”或再次“加入”后，会生成两个同样的“endpoint”，需要手工删除掉原有的才能正常运行。
