This issue has been closed because EF6 is no longer being actively developed. We are instead focusing on stability of the codebase, which means we will only make changes to address security issues. See the repo README for more information.

Using EF 6.4.4 (NuGet package) in VS 2022 17.0.2 (C#, ASP.NET app) has this issue when attempting to use “add-migration” or “update-database” from Package Manager Console. Get exact error as OP, so this is still happening on absolute latest available builds.

Only “workaround” that works for me is to use VS2019 at this time. Full disclosure: this website was originally created in VS 2017 and EF 6.0.
