.NET Core native prerequisites
==============================
This document outlines the dependencies needed to run .NET Core tools and applications.
For Operating System support, please refer to [the roadmap document](https://github.com/dotnet/core/blob/master/roadmap.md#technology-roadmaps).
## Windows dependencies
On Windows, the only dependency is the VC++ Redistributable. Depending on the version of Windows you are running on, the versions are changing.
> **Note:** these dependencies are chained in the installer, you only need to install them manually if you are using
> the installer script (`dotnet-install.sh` or `dotnet-install.ps1`).
* Windows 10
* [Visual C++ Redistributable for Visual Studio 2015](https://www.microsoft.com/en-us/download/details.aspx?id=48145)
* Pre-Windows 10
* Please make sure that your Windows installation is up-to-date and includes hotfix [KB2533623] (https://support.microsoft.com/en-us/kb/2533623) installed through Windows Update.
* [Universal CRT update](https://www.microsoft.com/en-us/download/details.aspx?id=48234) (you can get more info on what Universal CRT is in [this blog post](https://blogs.msdn.microsoft.com/vcblog/2015/03/03/introducing-the-universal-crt/))
## Ubuntu
Ubuntu distributions require the following libraries installed:
- libunwind8
- libunwind8-dev
- gettext
- libicu-dev
- liblttng-ust-dev
- libcurl4-openssl-dev
- libssl-dev
- uuid-dev
- unzip
## CentOS
CentOS distributions require the following libraries installed:
* deltarpm
* epel-release
* unzip
* libunwind
* gettext
* libcurl-devel
* openssl-devel
* zlib
* libicu-devel
## OS X
OS X requires the following libraries and versions installed:
* libssl version 1.0.1
## 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`).
