-* In [src/Framework/test/TestData.cs](/src/Framework/test/TestData.cs), update `ListedTargetingPackAssemblies` by incrementing the AssemblyVersion of all aspnetcore assemblies by 1 major version. Once dotnet/runtime updates their AssemblyVersions, we also need to update those in this file. They typically make that change at the same time as their TFM update, but we change our AssemblyVersions as soon as we update branding.
 * Add entries to [NuGet.config](/NuGet.config) for the new Major Version's feed. This just means copying the current feeds (e.g. `dotnet8` and `dotnet8-transport`) and adding entries for the new feeds (`dotnet9` and `dotnet9-transport`). Make an effort to remove old feeds here at the same time.
 * In [src/ProjectTemplates/Shared/TemplatePackageInstaller.cs](/src/ProjectTemplates/Shared/TemplatePackageInstaller.cs), add an entry to `_templatePackages` for `Microsoft.DotNet.Web.ProjectTemplates` matching the new version.
 * In [eng/targets/CSharp.Common.props](/eng/targets/CSharp.Common.props) for the previous release branch, modify the `<LangVersion>` to be a hardcoded version instead of `preview`. (e.g. If main is being updated to 8.0.0 modify the `<LangVersion>` in the release/7.0 branch). See https://learn.microsoft.com/dotnet/csharp/language-reference/configure-language-version#defaults to find what language version to use.
