You're targeting the nightly repo which contains the latest, unofficial builds. That requires special NuGet configuration to target the feed containing these package builds. See the NuGet info at https://github.com/dotnet/sdk?tab=readme-ov-file#installing-the-sdk.

Alternatively, if you just target mcr.microsoft.com/dotnet/sdk:9.0-preview instead (without nightly), you'll get the latest official Preview release which doesn't require this special configuration.
