Unable to access Caché Data Source with Entity Framework and Visual Studio 2017

I tried to access Caché using ADO.NET. This works fine but when I want to use Entity Framework, I can't access the Caché Data Source.

I'm using Visual Studio 2017, and followed the procedure described in Caché documentation.

(This document has been written  regarding VS2013)

Did some meet the same problem ?

Thanks in advance.
