Tried many times today to generate a project for v10.0.0-rc.1 everytime it just times out.
It should works as expected now. Can you please check it again.
Still having same issue today. Spinner just keeps spinning and never generates a download.
Sorry for this problem. We have fixed the issue and will update the website soon.
You should select .NET 5 as the Framework version when using v10-rc.1.
