我试图在Visual Studio 2015中使用EF 6.1.3中的代码优先方法。一切顺利，项目构建，但是如果我想添加一个＆＃34;新的脚手架项目＆＃34; - ＆GT; ＆＃34;带视图的MVC控制器，使用EF＆＃34;它一直给我以下错误：
Error running selected code generator.
The given documentId did not come from visual studio workspace"
Parameter id: documentId
如果我使用任何其他控制器，它工作正常，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！

我今天遇到了这个问题，我只是卸载/重新加载（右键单击VisualStudio中的项目＆＃34;卸载项目＆＃34;然后再次右键单击＆＃34;重新加载项目＆＃34; ;）VisualStudio中的项目，然后重建项目，我能够创建控制器。
