Where are Entity Framework Tools in EF6 and Visual Studio 2017?

At the installation of VS2017 you had to go to Individual Components to install those tools, don't think they are installed by default.

• Individual Components
  • SDK, Libraries and Components

You can run this install from the VS Installer

Entity Framework not appearing in Add New Item list in Visual Studio 2017

I had similar issue. I reinstalled Entity Framework 6 tools without luck, even reinstalled SQL tools (sorry, forgot exact name). But solution was very simple:

right-click the edmx file-> choose Open with->choose ADO.NET Entity Data Model Designer

For anyone looking at this, in my case the answer was that I was using a Code-First implementation of the Entity Framework, which apparently does NOT give you access to the Visual Tools.

So there is no EDMX file in Code-First Entity Framework.
