.NET Core 1.X requires the VC++ Redistributable when running on Windows. It is installed for you by the .NET Core installer. You need to install the Visual C++ redistributable manually if you are installing .NET Core via the installer script (`dotnet-install.ps1`), unzipping, or are attempting to run a self-contained .NET Core application.

## Installing the dependencies
Please follow the recommended practices of each operating system in question. For Linux, we recommend using your package manager such as `apt-get` for Ubuntu and `yum` for CentOS. For OS X and upgrading the libssl, we recommend using [Homebrew](https://brew.sh/); if you do use it, do not forget the link phase you need to do at the end of install (`brew link openssl --force`).
