.NET core sdk is still SPYING it's users even after it's "disabled" by "DOTNET_CLI_TELEMETRY_OPTOUT=1" environment variable

My dotnet sdk is extremely slow on creating new projects, so I dug a little on this abnormal behavior, and then I found that dotnet is making a lot of network requests. I use Wireshark captured those activities:

.NET core sdk sends requests to

go.microsoft.com:443
nam06.safelinks.protection.outlook.com:443
webpifeed.blob.core.windows.net:443
blob.byaprdstr14a.store.core.windows.net:443

when "dotnet new" runs.

Dotnet sdk won't return to the shell before those requests finished, and that's why it hangs after "Restore succeeded." message

Not a new thing: #6145
But I already set DOTNET_CLI_TELEMETRY_OPTOUT=1 on my machine

This set of hosts looks like dotnet new checking for template updates, rather than telemetry. #10564

Maybe you can set DOTNET_NEW_LOCAL_SEARCH_FILE_ONLY=1 and try again to try to rule that out? I found it in dotnet/templating#2093, which tracks improvements around the slowdown.

Sorry, hit a wrong thing.
