我试图在visual studio 2015中使用EF 6.1.3中的代码优先方法。一切都进行得很顺利，项目已经构建，但是如果我想添加一个“新的scaffold项”->“MVC控制器和视图，使用EF”，它总是给我以下错误：

Error running selected code generator. 
The given documentId did not come from visual studio  workspace"  
Parameter id: documentId

如果我使用其他任何一个控制器，它都可以正常工作，但我不想自己键入所有代码。我有以下文件，任何帮助将不胜感激。干杯
