Upgrading from 4.1 to 4.2 - Run Error Message

I'm upgrading our current project using source code, from 4.1 to 4.2. I ran the update scripts, deleted the files and backed up dataSettings.json and installedPlugins.json. When starting Presentation\Nop.web on IIS Express in Chrome, I'm getting the following error.

1>Nop.Web -> C:\Users\kfoubert\Source\Repos\burkhart-nopcommerce\Presentation\Nop.Web\bin\Debug\netcoreapp2.2\Nop.Web.dll

Solved this problem by deleting all the source including the .vs hidden folder. I also deleted the temp files associated with VS 2019. That seemed to fix it. I'm re-adding all our themes, plugins, and custom plugins and hopefully successfully commit it to our git repo.

These links helped solved the problem.

Hello.

I'm getting this error when im using continuous integration on azure.
The repo does not have any .vs, bin, obj folders.
Im unable to find any issues, and ive tried building, restoring everything locally without any problems.

On Azure DevOps there is an Clean option on the Get Source tab, which could perform different kinds of cleaning of the working directory of your private agent before the build is run.
