Cannot use Entity Framework in .NET standard 2 project
It looks like the actual question is "How can I create models and reverse engineer a database using EF Core like I could with EF 6" ?
The tooling is separate from the NuGet package. Visual Studio 2017 doesn't include modelling or reverse engineer tools for EF Core. Those are available through EF Core Power Tools an open source addon. You can find the code and documentation here

How can I use Entity Framework, or something similar within a .NET Standard project?
It appears as though EF is not supported in .NET Standard 2 which is really annoying!
So I have tried using Microsoft.EntityFrameworkCore.SqlServer and icrosoft.EntityFrameworkCore.SqlServer.Design
Whist I can install these packages, I cannot then add a model
I get the error
--------------------------- Microsoft Visual Studio --------------------------- The project's target framework does not contain Entity Framework runtime assemblies. Please review the target framework information in the project's property page. --------------------------- OK ---------------------------
How can I get around this?
I am seriously thinking to get rid of .NET Standard out of all my projects but that is a bit drastic!

Panagiotis Kanavos about 6 yearsIt's not. EF 6 came years before .NET Standard 2.0. The .NET Standard compatilbe version is EF Core.

David Browne - Microsoft about 6 yearsThe tooling for EF doesn't fully work with a project that targets only .NET Standard. But the runtime does. Try running the tooling in a console app targeting .NET core and moving the generated code artifacts into your .NET Standard class library.
