See also: - release announcement: https://github.com/dotnet/source-build/discussions/5461 - .NET 9.0.12 Runtime release notes: https://github.com/dotnet/core/blob/main/release-notes/9.0/9.0.12/9.0.12.md - .NET 9.0.113 SDK release notes: https://github.com/dotnet/core/blob/main/release-notes/9.0/9.0.12/9.0.113.md * It is beneficial for all our users (including LTS users) to have access to the latest .NET stack. [Test Case] * The package should build successfully in -proposed (respectively). * The packages should be installable on questing on amd64, arm64, s390x and ppc64el architectures. * Autopackage tests should pass. [Regression Potential] * The dotnet9 package has no reverse dependencies. * The upstream testing routine is usually satisfactory (see for example Microsoft's public Azure Pipeline for .NET related repositories: https://dev.azure.com/dnceng-public/public/_build), but there is always a risk of something breaking. [Other] * The tarball originated from here: https://github.com/canonical/dotnet- source-build/actions/runs/20970242805 * 9.0.12 is the version number of the .NET Runtime and 9.0.113 is the version number of the .NET SDK. * We are only building the 9.0.1xx feature band, because this is the only feature band that allows building from source.
