I am debugging an asp.net mvc 4 web site wsccc1. To traced any error, I designed my trace file log in web.config. I use Visual Studio 2012, the default hosted server is IIS Express.

<?xml version="1.0"?>
<configuration>
   <system.web>
     <compilation debug="true" targetFramework="4.5"/>
     <httpRuntime targetFramework="4.5"/>
     <customErrors mode="Off"></customErrors>

     </listeners>
  </source>
  </sources>
    <trace autoflush="true"></trace>
  </system.diagnostics>

But I couldn't find any .svclog file in C drive. There are log files in the path 'C:\Users\hui\Documents\IISExpress\TraceLogFiles\wsccc1'. All the files begin with 'fr' such as 'fr00400.xml'. It has the exception information.

My question is why it begin with 'fr'? Is it referred to French but I am in USA?

Also why I could not generate 'C:\myMessages.svclog'.

中的文件C:\Users\hui\Documents\IISExpress\TraceLogFiles\wsccc1是 IIS 日志文件：HTTP 请求 url + 响应状态 + 时间戳 +.... HttpLoggingModule 是必需的，它与 WCF 甚至 asp.net 无关。

*.svclog是 WCF 跟踪文件：这通常需要编辑配置文件以启用 WCF 跟踪（如您所做的那样）。一个很好的教程在这里。

还有为什么我不能生成'C:\myMessages.svclog'。

可能是因为安全。为 C 盘上的每个人添加完全控制权（不推荐）或指定一个公共目录（例如 c:\logs），每个人都可以在其中生成跟踪日志。

编辑 ：

为什么 IIS 日志文件以“fr”开头？

即使我是法国人，它也不是为我们制作的。fr 在这里表示Failed Request。这是 IIS 中称为“失败的请求跟踪”的新功能：它旨在缓冲请求的跟踪事件，并且仅在请求“失败”时将它们刷新到磁盘。这里解释。
