Hello, I don't see the reason the package ID has to be the lower case. Any reason for this change?

[davidxuang]

It's failing.

Is this being reviewed? This does not affect development much because it can be bypassed if you name a version explicitly when executing the script, but it's not practical to do this with CI every time .NET receive a new minor series.

sorry for the late review.
I still don't see the reason this should be changed. To me, it looks just an additional job in the script.
Additionally, as far as I know, the NOT ToLower() version is the exact url.
I don't understand the original url fails on your side.

For no way the current implementation is working.

Ok, so you mean it could be failing in some CI or other system that probably handle it differently.
I will merge it and see if this could solve the issue. Thanks for the contribution.
