WCF服务跟踪

如果在开发过程中，WCF服务出现问题，我们可以通过服务引用，然后直接断点调试进去。然而，对于已经发布的服务，出现错误时，寻找错误信息会变得麻烦。

幸好，微软提供了服务跟踪查看器工具 (SvcTraceViewer.exe)这个工具来跟踪已发布的服务。

可以在文件夹： C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\Bin找到(我的系统是WIN7,.NET 4.0)

配置服务跟踪相当简单，可以用上面的SvcConfigEditor.exe来打开服务的config文件配置。

也可以手动修改配置，增加一个diagnostics的配置节点。
