Visual studio 2015 尝试生成脚手架API控制器时VS2015中出错

我试图在我的测试解决方案中生成脚手架组件。我在我的项目中右键单击并单击“添加脚手架项目”，然后选择“实体框架中带有操作的API控制器”。在那里，我选择了我的模型类和上下文，当我单击Add时，它抛出以下错误：

错误 运行所选代码生成器时出错：“未处理的异常：System.TypeLoadException:无法加载类型”Microsoft.VisualStudio.Web.Codegeneration.Core，版本=1.1.0.0，区域性=中性，PublicKeyToken=adb9793829ddae60”，位于Microsoft.VisualStudio.Web.Codegeneration.Tools.Program.Main（字符串[]args）“

我确信这是由解决方案的依赖性问题引起的。到目前为止，我已经尝试包括Microsoft.VisualStudio.Web.CodeGeneration.Core库，但没有解决问题

这些是我的项目的依赖项：

提前感谢您的帮助。

这个问题是由依赖项中的错误版本和平台上不兼容的代码生成器引起的

将项目打开/转换为VS2017社区，并与VS2017的空白新社区进行比较，可以看出问题所在。我强迫VS2015在.Net Core 1.1.1和代码生成器版本（如果不可用）上工作
