System.TypeLoadException: Could not load type 'System.Data.Entity.Infrastructure.Design.Executor+GetContextType' from assembly 'EntityFramework

I created a new Framework Winforms XAF 21.1.4 Winforms project using EF 6.2

When I tried to enable migrations via Package Manager Console I got

System.TypeLoadException: Could not load type 'System.Data.Entity.Infrastructure.Design.Executor+GetContextType' from assembly 'EntityFramework, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.

I have to downgrade the version install of EntityFramework and reinstall the latest version again. It worked like this.

This is what actually get changed: (my project target .net 4.8.1)

in packages.config file -> The version was changed from 461 to 481

  <package id="EntityFramework" version="6.4.4" targetFramework="net481" />

I upgraded to EF 6.4 via Nuget and was then able to enable-migrations
