Packages to be added:
-- Microsoft.AspNetCore.Identity.EntityFrameworkCore -- Microsoft.EntityFrameworkCore -- Microsoft.EntityFrameworkCore.SqlServer -- Microsoft.EntityFrameworkCore.Design
The above could be added from 'NuGet - Solution' by simply browsing the names.
There is one more that has to be installed from 'Package Manager - Console'.
Use the following command: dotnet tool install --global dotnet-ef --version AnyVersion
The versions should match.
