Installing Visual Studio 2017 with GitHub extension
NOTE: This guide also contains instructions for installing the Visual Studio GitHub extension, you'll need to do this each time you install a new version of Visual Studio.
The installer for Visual Studio 2017 requires us to perform an extra step to install the components that we need.
Make sure you select .NET desktop development (top right)
Visit http://www.visualstudio.com/downloads and select Visual Studio Community (Free download). Download and run the installer.
If the installer prompts you to install the .NET Framework, then follow the links to install this first (the first link takes you to a page with the option to "Download .NET Framework 4.6 or higher".
The second link you need is circled in red below.
The installer requires the computer to restart before the setup is complete. Once you've restarted, launch Visual Studio 2017 and sign in with your Microsoft account.
Navigate to the Tools menu and select Extensions and Updates....
The Extensions and Updates window initially shows the extensions that you already have installed. Make sure you click Online to search for online extensions (shown in red below), you can then search for github using the search box at the top right (shown in green).
Click download. You will have to restart Visual Studio before the extension will be installed and made available.
Visual Studio 2017 will be installed alongside any old copies of Visual Studio - so it's easy to end up with VS2013, VS2015 and VS2017 all installed on your computer at the same time. To remove the old versions, go to Control Panel > Programs > Uninstall a program, double click the entry for Microsoft Visual Studio Community 2013 (or 2015) and select Uninstall
