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 during setup to install the components that we need, when you reach the screen below, make sure you select .NET desktop development (in the box in the top right). If you miss this step, you can add it later as an extra workload
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 to follow is circled in red in the image 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.

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
