我正在尝试在VS2010中开发应用程序的同一台计算机上发布WCF应用程序，但在访问数据库时我一直收到以下错误。数据库是MySQL，我使用MySQL连接器6.3.6和EF4。我认为这是某种权限问题，因为我在通过VS查看时可以看到该表的数据，但是当我尝试从VS发布到IIS时，通过浏览器访问应用程序时出现此错误。
非常感谢任何帮助。再次感谢。
此调用正在运行并返回可用的集合，其中包括一个表newtables：
http://localhost/WcfService1/WcfDataService1.svc
以下是我试图访问该表的方式：
http://localhost/WcfService1/WcfDataService1.svc/newtables
这是返回的错误：
