I put this together in order to get IIS running in a Console app, .Net Core style, but not actually .Net Core. Wanted to run an old web application in Service Fabric.

It uses the IIS Hostable Core interface to spawn up a full IIS copy in memory. Provides a nifty Fluent-like interface for configuring ApplicationHost.config and Web.config files.

In case anybody is interested.
