Perhaps @nishanil can help

@carlossanlop I haven't seen this error before. Based on the internet search results it looks like it happens due to the mismatch of the target OS specified in docker image and the container OS. Can you try resetting Docker and creating a new project? I will also verify these steps from my side. Also, ensure you have the latest .NET 5 SDKs installed.

@nishanil The request is for @defney, who reported the issue.

[nishanil]

Oops! Thanks.

@defney I'll mark this issue as needs-more-info. It will get auto-closed if we don't get a reply in the next week.

We tested this - all the steps work fine on macOS with .NET 5 SDKs installed.

Thank you for your help !
