Same error occurs on visual studio and devops pipline

Tired to clean obj/bin directories, restarted visual studio, cleaned devops _work directories nothing happens always same error

@eslamo Looks related to #25555. However, it is interesting that in this case it is failing this way in the devops pipeline. Can you provide some more information about the environment for that pipeline? Is it runnin on the same machine that you are doing Visual Studio builds? Also, are you using VS Code at all?

[eslamo]

@ajcvickers for Devops it's running on 2019 server with agent for windows running on the same machine and I don't use VS Code. I only use VS

By the way I tried an OSX agent and It built without this issue I think this issue is only related to windows cause I tried it in Windows 10 for local build and Devops pipeline using windows agent and I had the same result for error.

@ajcvickers after reading issue #25555 I can make sure that the issue related to a bug in version 6.0.0-rc.2 cause both machines is running same version local and devops. I'll try to use older version as suggested in #25555 and try to find if it works in pipeline or not.

BTW this is a canned response and may have info or details that do not directly apply to this particular issue. While we'd like to spend the time to uniquely address every incoming issue, we get a lot traffic on the EF projects and that is not practical. To ensure we maximize the time we have to work on fixing bugs, implementing new features, etc. we use canned responses for common triage decisions.
