@Anandkumar Yadav Are you using the blob storage to log your conversation state? I have tried this scenario and the sample did work.
I also found a simple solution that you can use with minimal effort to log the conversation in a blob container. This can be achieved using a basic echo bot using the readily available sample from VS marketplace. Once you install the VSIX package you can try updating the echo bot by following the steps in this document for C#. The default solution uses in memory storage but after updating the storage account settings it should log the utterances in the container configured.
Here is a screen shot from my emulator and the log in the container.
