Please create an Offline DirectLine Emulation that is supported by Microsoft.

If you have industry standards that prohibit Ngrok this can make debugging a nightmare.

The Bot Framework Emulator has a built in Direct Line Controller. Why is this not open source for use with webchat? There are a few brave souls who have attempted to build emulators however both do not support Direct Line App Service Extensions and WebSocket.

Microsoft should support offline-directline implementations officially.
