VS2015 WPF 设计器无法加载 FileLoadException HRESULT：0x80131040

Question

我正在 VS2015 中创建一个 WPF 项目，一切正常，甚至应用程序编译和运行成功，但我无法加载设计器。我收到以下异常：

System.IO.FileLoadException Could not load file or assembly 'Microsoft.Windows.Design.Interaction, Version=4.3.0.0, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference.

其他一切正常，只是设计器没有加载。

好的，所以使用标准设置重新安装 VS2015 对我来说完成了这项工作。现在一切正常。

问题原因： 我之前安装了带有自定义选项的 VS，并且只选择了 Web 工具。这就是为什么很少有包裹丢失的原因。所以用标准设置重新安装就可以了。
