This tap contains different versions that you can install in parallel to the latest version provided by the official cask.

Install one of the previous versions by tapping this repository and running the install command.

brew tap isen-ng/dotnet-sdk-versions
brew cask install <version>

dotnet --list-sdks

Because the dotnet packages uses shared dependencies between different versions, it is unwise to delete these dependencies when uninstalling a particular version as it will cause other versions not to work.

If there is a need to purge these dependencies, use the zap command:

brew cask zap <version>

Important: Uninstalling the offical version will also remove these dependencies, so you'll need to reinstall the particular version you want to use again.

The dotnet command will automatically use the latest appropriate version unless specified by global.json.
