This is not an issue. Looks like the dependencies you are installing cannot retrieve System.Memory 4.5.2 from the nuget feeds you have installed.
Please add https://myget.org/F/workflow to your packages sources (in package manager) and try again. Also please share with us the project.json file created in the project folder after you encounter these errors.
Thx. After enabling the ‘nuget.org’ source, the warning is no longer displayed when creating new projects.
I am currently testing Release 2021.10 based on a separated installation of a community-version. Could the above case become a problem on our enterprise installation, if we don’t want to enable this source because we only use packages hosted on our on-premise Orchestrator?
