[Unresolved] Microsoft.DotNet downloads are slow and don't match official links

[stevenlele]

The installer links in the manifests submitted by @dotnet-winget-bot (https://github.com/microsoft/winget-pkgs/pulls?q=is%3Apr+DotNet+in%3Atitle) don't match the official links, and the download speed is very slow in some regions (e.g. China) compared to the official ones.

For example, the x64 link in #167532 is https://dotnetcli.azureedge.net/dotnet/WindowsDesktop/8.0.8/windowsdesktop-runtime-8.0.8-win-x64.exe, whereas the official link listed in the release notes and official download page is https://download.visualstudio.microsoft.com/download/pr/907765b0-2bf8-494e-93aa-5ef9553c5d68/a9308dc010617e6716c0e6abd53b05ce/windowsdesktop-runtime-8.0.8-win-x64.exe, which downloads a lot faster than the former one in China (<100 KB/s vs ~5 MB/s).

@mthalman Please consider fixing your download network or switching to the official links instead.

@rbhanda - Can we make any CDN configuration changes to improve this?

@mthalman Should I reopen this in a dotnet repo? Which one?

[stevenlele]

For the record, the CDN was changed to a new one in #202037 which is a bit better but still much slower than the official links (download.visualstudio.microsoft.com). There seem to be no willingness to change the links to the fastest ones.

[mthalman]

download.visualstudio.microsoft.com isn't anymore official than builds.dotnet.microsoft.com. In fact, the goal is that builds.dotnet.microsoft.com will be the sole location for .NET bits: dotnet/core#9675.

If you're experiencing issues with the builds.dotnet.microsoft.com CDN, please log an issue at https://github.com/dotnet/core.
