I have latest windows docker desktop edge and ithub.com/docker/buildx v0.3.1-tp-docker 6db68d0

When I try and use default buildx context i get told push is not supported - this happens in both linux and windows modes. Using the procedure documented here works for linux, but if i switch to windows containers and do the same procedure (with different builder context name) it utterly messes up and generates system named pipe errors on buildx ls, only an uninstall of docker desktop and manual removal of c:%username%.docker fixes it.

This leads to believe that buildx is not yet working with windows containers - is that correct or should i submit a more detailed bug?
