It would be beneficial to have some examples of how using PolySharp helps. I'm keen to provide a presentation for my colleagues that underlines the pros of PolySharp. A demo code base - one project without PolySharp (and with errors) and one with PolySharp (and
without errors) - would be helpful. Also, some words about typical alternatives might be helpful to advertise the adoption of PolySharp.

In my case, I mentioned spontaneously the helpful polyfill for record types and immediately got the feedback from the team: It makes no difference whether we add a reference to PolySharp or provide a class IsExternalInit. Okay, my fault for not having the best sample, but also other samples on various internet resources underline benefits of PolySharp, that are not really benefits of PolySharp, instead they come with Latest.
