Xamarin Offline Installation

Installing Xamarin can be really painful using the installer available from their website. A better option is to download the installer from here then downloading the components one by one, install all of them and then running the installer so that it can configure the components.
As you can see from the image below the installer does the downloading and installation at the same time which makes it slow.

Using a download manager like IDM you can lessen the time you require to install Xamarin.
