MemoryCache.Default can also serve as a "bridge" if you're migrating a classic ASP.NET MVC app to ASP.NET Core, because there's no "System.Web.Caching" and "HttpRuntime" in Core.

I also wrote a small benchmark to store a bool item 20000 times (and another benchmark to retrieve it) and MemoryCache seems to be two times slower (27ms vs 13ms - that's total for all 20k iterations) but they're both super-fast and this can probably be ignored.
