如果您没有安装Visual Studio,以下步骤适用于我:

1. 下载Portable Tools 2扩展并使用该/buildmachine开关安装它:PortableLibraryTools.exe /buildmachine

2. 下载Portable Class Libraries v4.6并安装它.

3. 复制内容(目录v4.0,v4.5和v4.6的)C:\Program Files (x86)\Microsoft .NET Portable Library Reference Assemblies 4.6到C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETPortable(覆盖所有现有文件).[如果您想要安全起见,请备份原始文件!]
