Error 412 - Manage Bot state Data

Question

I've been following Bot Framework documentation to store Bot-Data but even after using the code snippet provided here for handling concurrency I still get error 412 in the emulator. Can you please tell me if I'm saving & retrieving the Bot state correctly.

I've tried setting breakpoints when I'm saving the bot state but it doesn't hit either of the catch blocks.

Answer 1

In the context of a dialog, I would try using context.PrivateConversationData instead of the StateClient.

You can check the State C# sample to fully understand how this works.
