500-内部服务器错误，Windows Azure云服务

Question

I have just switched from WCF Service to Windows Azure Cloud Service. I have copied over my codes from my WCF service into the Cloud service. When i run the website i get

500 - Internal Server Error. There is a problem with the resource you are looking for, and it cannot be displayed.

Here is my code for my Web.config:

Answer 2

与其将整个代码从服务复制到云程序，不如在解决方案中添加一个Cloud项目，然后右键单击角色并从解决方案中添加现有角色。
