 - `UseLocalizationResources` and `LocalizationResources` were removed. This feature was used mostly by the `dotnet` CLI to add missing translations to `System.CommandLine`. All those translations were moved to the System.CommandLine itself, so this feature is no longer needed. If we are missing support for your language, please [report an issue](https://github.com/dotnet/command-line-api/issues/new/choose).
 - `UseTokenReplacer` was removed. [Response files](syntax.md#response-files) are enabled by default, but you can disable them by setting the <xref:System.CommandLine.CommandLineConfiguration.ResponseFileTokenReplacer> property to `null`. You can also provide a custom implementation to customize how response files are processed.

 In some cases, the .NET CLI doesn't use kebab case for command, option, or argument names. For example, there is a .NET CLI option that is named [`--additionalprobingpath`](../../core/tools/dotnet.md#additionalprobingpath) instead of `--additional-probing-path`.
