title: How can I always update a dotnet tool to the latest version including previews?
body: <p>When you want to update or install a dotnet tool you need to explicitly provide the version for preview versions.
  It doesn't work in our DevOps environment because we need to be the package always the latest (including preview version).
  There's no parameter like <code>--preview</code> to update/install the latest version including the preview version.
