Polyfill'sOperatingSystem.IsAndroid()callsunameviaProcess.Start()to determine whether the app is running on Android, which is fairly problematic as 1) it spawns a process for that, which isn't ideal 2) it does so even on non-Android platforms like Windows, which generates unnecessary first-chance exceptions.Unfortunately, it's not easy to opt out specific polyfills with the
Polyfilllibrary. WhileMeziantou.Polyfillcurrently exposes fewer polyfills, it's a lot easier to opt-out specific types or members.This PR replaces
PolyfillbyMeziantou.Polyfilland adds internalOperatingSystempolyfills similar to what we have before moving toPolyfill.
