I rebuilt my dev machine recently and reinstalled the Service Fabric 2.1 SDKs from here: https://azure.microsoft.com/en-us/documentation/articles/service-fabric-get-started/
The rest of the devs on my team were still on 2.0 and we weren’t ready to upgrade to 2.1. There’s no obvious way to install 2.0. The only way I could find was through the Web Platform Installer.
So if you need to install a previous version of the Service Fabric SDK
1. Download Web Platform Installer https://www.microsoft.com/web/downloads/platform.aspx
2. Search for “service fabric”
3. Install your desired version.
