The following sections demonstrate the size improvements for Windows, Linux and macOS, including container delivery. They detail the process and commands that were used to determine the product sizes, enabling you to reproduce the same results in your own environment. To keep thing simple, zips and tar balls were downloaded from dotnet/core-sdk as opposed to the official installers.
