Any project that targets .NET 4.7 can use C# 7 tuples without adding a Nuget package. You'll have to install it manually:

1. Upgrade to Windows 10 Creator's Update (10.0.15063), or install .NET Framework 4.7 on other versions of Windows: https://www.microsoft.com/en-us/download/details.aspx?id=55170
2. From the Start menu, run Visual Studio Installer and click Modify. Go to "Individual components" and check the following two components:
   • .NET Framework 4.7 SDK
   • .NET Framework 4.7 targeting pack

It doesn't work out-of-the-box on Windows 10 Creator's Update because Microsoft omitted the .NET 4.7 components from the ".NET desktop environment" workload. I filed a bug, but they closed it as Not a Bug:
