阿里云共享虚机 不支持code first

环境：asp.net mvc .net4.5

EF code first 程序部署到阿里云虚机上出错，本机上是没有问题的，错误提示：“无法检查模型兼容性，因为数据库不包含模型元数据。只能检查使用 Code First 或 Code First 迁移创建的数据库的模型兼容性。”

具体错误如下：
This XML file does not appear to have any style information associated with it. The document tree is shown below.

出现错误。

“ObjectContent`1”类型未能序列化内容类型“application/xml; charset=utf-8”的响应正文。
