I have encountered the following error:

The tooling in the version information here is a little out of date. The solution in this case was to perform a thorough uninstall of Xamarin in Windows and reinstall using the latest available Stable release. I linked @Dorad to the direct download, but you can find this by signing into Xamarin.com, navigating to the Downloads page and selecting the download from the relevant drop-down list for your OS / desired Xamarin platform:
