推荐答案

如果您没有安装 Visual Studio，以下步骤对我有用:

If you don't have Visual Studio installed the following steps worked for me:

1. 下载 便携式工具 2 扩展并使用 /buildmachine 开关安装它:PortableLibraryTools.exe/buildmachine

1. Download the Portable Tools 2 extension and install it using the /buildmachine switch: PortableLibraryTools.exe /buildmachine

下载可移植类库 v4.6 并安装它.

复制C的内容(目录v4.0、v4.5和v4.6):\Program Files (x86)\Microsoft .NET Portable Library Reference Assemblies 4.6 到 C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETPortable(覆盖任何现有文件).[如果您想安全起见，请备份原始文件！]

Copy the contents (directories v4.0, v4.5 and v4.6) of C:\Program Files (x86)\Microsoft .NET Portable Library Reference Assemblies 4.6 into C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETPortable (overwriting any existing files). [Backup the original files if you want to be on the safe side!]
