When using the Invantive Bridge for Exact Online, Visual Studio complaints that even after installation of Invantive Bridge, that the references are missing.
How can I find the references of Invantive.Data namespace?
You can best reference the nuget package Invantive.Bridge.Developers. It takes care of everything.
Alternative is to include the references all yourself (there are a lot since all 50-60 platforms are included) chosing from c:\program files (x86)\invantive software\invantive bridge. New releases automatically add this one to your Visual Studio 2017 folder.
Please also note that this only works with 4.7 framework and netstandard 2.0.
