About Bot FrameworkV4

[The-Mojoo]

Hi Team,

I have completed the development of the TeamsApp by BFV3 version, but there are currently some features that only V4 can do, and I really want a full Demo like this project, and I've only found
Https://github.com/OfficeDev/BotBuilder-MicrosoftTeams-dotnet/tree/master/CSharp/Samples
Demo here, I encountered a lot of problems when the integration, so when can there be a BFV4 version?
I believe that I do not need this alone.

Thanks,

I am also looking for the BFV4 version.
