Special notes for your reviewer:

Storage Blob Data Contributor is an Azure AD RBAC role that can read and write data to storage containers. Its typically used together with Managed Identities. The Storage Blob Data Contributor only have a very limited set of permissions (See image)

Is it necessary to loop over all containers? Would it not be just enough to see that the operation returns?

Any chance you can review and merge this pull request @sungam3r its been pending for quite a while, and is a minor change.

I'm OK to review/merge this one when you rebase your changes onto actual master. The reason is to run CI tests that were added some time ago into master.

@sungam3r its been rebased, but you need to run/approve the workflow.

@CarlosLanderas @unaizorrilla global.json looks like this
{ "projects": ["src", "tests", "samples"], "sdk": { "version": "6.0.100" } }

Now all CI will fail because they use 6.0.x version and current version is 6.0.200.

Options:

1. Configure global.json - https://docs.microsoft.com/en-us/dotnet/core/tools/global-json?tabs=netcore3x#rollforward
2. Remove global.json

Honestly, I would prefer the second, I have never seen a lot of benefit in it.

Hi @sungam3r

• @carlosrecuero

What about add rollForward to global.json?

{
  "sdk": {
    "version": "3.1.102",
    "rollForward": "latestPatch"
  }
}

[carlosrecuero]

Hi @unaizorrilla , i think is a good and quick option.
