Question

当我尝试在我的网站项目中创建New Scaffolded Item时，我收到以下消息：

Error

运行所选代码生成器时出错：

＆＃39;获取类型＆＃39; SomeProjectInMySolution时出错。SomeModelInThatProject＆＃39;。

尝试重建项目。＆＃39;

现在，似乎无法创建它，因为它位于不同的上下文中。

我尝试了this answer提出的建议。但是，失败了。

我还能尝试什么？

这就是我填写生成形式的方式：

注意：

我正在使用：

Entity Framework6 6.1.3
EntityFramework Reverse POCO Code First Generator:在该特定项目中生成上下文。
我的所有项目都是在64位平台上构建的。
我的网站项目ConnectionString中也有正确的Web.config。

非常感谢

更新

我也试过this。但是，没什么。

我注意到在尝试创建项目时，控制台输出：

尝试安装版本＆＃39; 6.1.1＆＃39; ＆＃39; EntityFramework＆＃39;但该项目已包含不同的版本。跳过...

但是，我的所有项目都有6.1.3。尝试降级为6.1.1。但是，仍然没有工作。为什么它甚至显示该消息？

<package id="EntityFramework" version="6.1.3" targetFramework="net451" />

Answer 1

我终于找到了解决这个可怕问题的方法：

有几篇帖子确定它与x64平台有关。所以，在最后一次绝望的尝试中，我只是将平台更改为Any CPU（每个项目），然后运行Scaffolded项目生成器，最后切换回64-bit。

我不确定为什么会这样。我的同事提到Visual Studio是用32位构建的，也许是造成这个问题的原因。我真的不知道。但是，我希望这可以帮助将来遇到同样问题的人。

感谢所有尝试过的人。

我在asp.net中从控制器生成视图时遇到了类似的问题。

这里的问题是，我的模型类继承自项目之外的类，当我从类中注释继承时，生成工作并且我能够再次进行继承。

像这样：

所以我生成了然后我删除了评论斜杠。

public class Employee //: PersonBase {...}

不知道它是否对您有所帮助，但值得一试。
