Asp.net core using storage nuget package from 2017 results in nuget conflict

[hansmbakker]

Describe the bug

Microsoft.AspNetCore.DataProtection.AzureStorage depends on WindowsAzure.Storage, a nuget package from 2017 😱. This creates conflicts e.g. when also using Nuget packages that rely on its modern replacement (Microsoft.Azure.Storage.*). E.g. Bot Framework does this.

This is an issue for my project.

Error I'm getting:

The type 'CloudStorageAccount' exists in both 'Microsoft.Azure.Storage.Common, Version=9.4.2.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' and 'Microsoft.WindowsAzure.Storage, Version=8.1.4.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'

We are updating DataProtection.AzureStorage in 3.0 to use the new Microsoft.Azure.Storage.Blob dependency. This should resolve the compiler conflict in the scenario originally reported.

If you want to use Microsoft.Azure.Storage.Blob in 2.1 and 2.2 apps along with DataProtection.AzureStorage, you can resolve the compiler error by fully-qualifying the type reference, or adding a using such as this to the top of your file.

using CloudStorageAccount = Microsoft.Azure.Storage.CloudStorageAccount;

Closing as we do not plan to update 2.1 or 2.2 to use Microsoft.Azure.Storage APIs.
