After upgrading .net from 3.1 to 6.0 We are getting this error in the pipeline Create ef migrations

dotnet exec step seem to be targetting old frameworks, we have updated EF as well.

My best guess would be that since it seem to be using bin, it is a attempting to use things from a older build to exec a current updated.

Is there a way to clear obj and bin on build server?

But on the build server, it would be spinning up a new container? How is it using bin from a old build

Figured it out, in a build step it was building 3.1. Removed step and script worked.
