Is it possible to create LUIS Dispatch for existing V3 Bot ? We have v3 bot that's in production and we have gone so far now so its difficult to switch over v4 Bot. However, there are awesome capabilities like LUIS dispatch tool that we would like to leverage.
Given the fact that the source code is available for the LUIS components and the provided examples, I think you can use this tool on v3 bot after some modifications.
It looks like the dispatch tool is only preparing a custom LUIS app that you will query from your bot, so nothing really linked to v4 of bot builder.
