If you're trying to run EF Core migrations using commands like dotnet ef migrations add NAME or dotnet ef database update and you're getting errors like the one shown in the screenshot above, here's the fix.

You need to install the dotnet-ef tool, ideally globally so you can run it from anywhere. To do so, run this script from a command prompt/terminal window:

dotnet tool install --global dotnet-ef

Once you've done so, you should be able to run your dotnet ef commands successfully.
