After Upgrades to .Net Core 3.0 dotnet ef is missing

General

After upgrading Visual Studio 2019 from 16.0/16.1/16.2 to 16.3 .Net Core get's upgraded to 16.3
All Projects that are useing Entitfy Framework are failing.

This helps: dotnet tool install --global dotnet-ef
BUT
global didn't install dotnet-ef for the machine globally, only for the user account.
A build Agent typically doesn't run in the same identity than the user that is installing Visual Studio.

It's very annoing that .Net Core 3 installation prevent building .Net Core 2.x Code in it's default installation.

Copied from original issue: dotnet/core#3570

I'm having this same issue as I'm trying to add this to my ,NET Core 3.0/2.2 apps - see #18276

You can also use a global.json file to continue using the 2.2 SDK in the project:

{
  "sdk": {
    "version": "2.2.402"
  }
}

(The 2.2 SDK includes dotnet ef so it should work as it used to without the need to install it separately)

Thank you @bricelam - seems to be working for my builds!
