使用SVCUtil为WCF生成代理时，我遇到了错误。错误信息如下：

Warning: No code was generated.
If you were trying to generate a client, this could be because the metadata documents did not contain any valid contracts or services
or because all contracts/services were discovered to exist in /reference assemblies. Verify that you passed all the metadata documents to the tool.
Warning: If you would like to generate data contracts from schemas make sure to use the /dataContractOnly option.
在数据契约中添加枚举成员后，一切都正常工作。
