>>在正常安装期间是否需要Internet连接才能安装Visual Studio 2015的所有组件?

对于您的问题，您需要互联网连接才能安装VS.

For your question, you need the internet connection to install VS.

通常，有两种下载VS安装程序的方法:Web安装程序或ISO映像.

Normally, there are two ways to download VS installer: Web installer or ISO image.

即使是ISO，它也不包含所有资源包，例如Visual C ++模板，UWP工具等.

Even if the ISO, it doesn't contain all the resource packages, such as Visual C++ templates, UWP tools etc.

如果您尝试安装VS，请检查您的网络连接并确定没有问题.

If you try to install the VS, please check your network connection and sure it's ok.

如果创建新项目失败，则该项目模板可能丢失或损坏，建议您下载并插入一个良好的ISO进行修复.请使用

If you failed to create a new project, the project template could be missing or broken, I suggest you download and insert a good ISO to repair. Please use  FCIV to verify hash of the ISO.

在VS设置过程中，还请确保 网络连接.

During the VS Setup, please also ensure the well operation of Network connection.

如果您不方便在此计算机上连接Internet，则可以使用 用于离线安装的 /layout 选项.它允许您将全套文件下载到本地文件夹，并且该文件夹包含用于脱机安装的所有必需文件.

If it's inconvenient for you to connect Internet on this machine, you could use the /layout option for an offline installation. It allows you to download the full set of files to a local folder, and this folder has all the necessary files for offline installation.
