Cannot AzureBlobStorage initialization in Bot Framework 4.9

Question

I am implementing "AzureBlobStorage" by referencing "Microsoft.Bot.Builder.Azure", but when I initialize I get an error with "CloudStorageAccount".

Error CS7069 Reference to type 'CloudStorageAccount' claims it is defined in 'Microsoft.Azure.Storage.Common', but it could not be found QBotSolution

It looks like Visual Studio can't determine which package you're trying to use. If you're just looking to do traditional bot state management, you should remove these packages:

1. Azure.Storage.Blobs
2. Microsoft.Azure.Cosmos.Table
3. Microsoft.Azure.Storage.Blob
4. Microsoft.Azure.Storage.Common

For bot Blob storage, you should only need Microsoft.Bot.Builder.Azure, so be sure to include using Microsoft.Bot.Builder.Azure; at the top of whatever file you're trying to use this in.
