C#: ADO.NET Entity Data Model

Hi
I'm using MS Visual Studio 2019!

working through 20483-Programming-in-C-Sharp training course I'm at Module 7: Accessing a Database
and looking at the demo from here

@step 9 "Add New Item – FourthCoffee.Employees dialog box click ADO.NET Entity Data Model, "  I don't see this  searching "ADO" or "Entity" finds ZERO

I thought I might need a Nuget package   so Search for ADO and installed EntityFramework 6.2.0  resulting in Errors

Severity      Code      Description      Project      File      Line      Suppression State
Message      IDE0060      Remove unused parameter 'args'      FourthCoffee.Employees      E:\VB\20483-Programming-in-C-Sharp-master\Allfiles\Mod07\Democode\Demo1\Starter\FourthCoffee.Employees\FourthCoffee.Employees\Program.cs      7      Active
AND

Severity      Code      Description      Project      File      Line      Suppression State
Warning      NU1701      Package 'EntityFramework 6.2.0' was restored using '.NETFramework,Version=v4.6.1' instead of the project target framework '.NETCoreApp,Version=v2.1'. This package may not be fully compatible with your project.      FourthCoffee.Employees      E:\VB\20483-Programming-in-C-Sharp-master\Allfiles\Mod07\Democode\Demo1\Starter\FourthCoffee.Employees\FourthCoffee.Employees\FourthCoffee.Employees.csproj      1      

Any suggestion where to find ADO.NET Entity Data Model as I can't proceed to the course exercise as this is doing similar

BTW: If you attempt this @  1 copy the FourthCoffee.sql file to "C:\Users\User.Name" before running SetupFourthCoffeeDB.cmd.
