I created a new Project in Visual Studio 2017 with .Net Core 2.0. It turned out, that there is no Ado.net entity data model item in the new item dialog.
I've seen this link Missing “Ado.Net Entity Data Model” on Visual Studio 2013 . But there is no EFTools.msi in the suggested directory nor can i install Entity Framework 6 Tools for Visual Studio 2012 & 2013 for Visual Studio 2017.
Regarding this link: Can't find ADO.net Entity Data Model template in VS2017 I checked as well under Programms&Features->Visual Studio 2017->Change->Components and there Entity-Framework Tools 6 is selected an apparently installed.
I tried with starting Visual Studio 2017 as Administrator as well.
Every help is very appreciated.
