Visual Studio 2017 Pro in Windows 7 with .net framework 4.7 developer kit installed and without System.ValueTuple nuget.
Intellisense provides the correct tuple name in the suggestion list, but when chosen, writes the old tuple name (Item1, Item2, etc.)
Is this a Visual Studio bug, or a settings issue?
It was a Resharper bug. I upgraded Resharper to 2017.1.3 and now intellisense resolves correctly.
