Answer 1

This can happen if you have both Microsoft.EntityFrameworkCore.SqlServer installed alongside an older version of EntityFramework say 6.x

In Visual Studio, go to Project/Manage Nuget Packages...

Take a look through the Installed list and if more than one version of EntityFramework is installed, uninstall all older versions, leaving only the latest version.
