    var serviceClient = new BlobServiceClient(storageConnectionString);
    var accountInfo = serviceClient.GetAccountInfo();
    Console.WriteLine(accountInfo.Value.SkuName);
}

// GetBlobContainers works using DefaultAzureCredential.
{
    var storageAccountName = Environment.GetEnvironmentVariable("STORAGE_ACCOUNT_NAME");
    var accountUri = new Uri($"https://{storageAccountName}.blob.core.windows.net/");
    var serviceClient = new BlobServiceClient(accountUri, new DefaultAzureCredential());
    foreach (var container in serviceClient.GetBlobContainers())
    {
        Console.WriteLine(container.Name);
    }
}

// GetAccountInfo fails with an HTTP 404 Not Found using DefaultAzureCredential.
{
    var storageAccountName = Environment.GetEnvironmentVariable("STORAGE_ACCOUNT_NAME");
    var accountUri = new Uri($"https://{storageAccountName}.blob.core.windows.net/");

Thank you for your feedback. This has been routed to the support team for assistance.

@cataggar According to this permission table for data operations, looks like Get Account Information isn't supported.

The same is called out in the REST API reference for the underlying request being made.

You should be able to get the same data using the Management SDK instead, i.e., the GetProperties or GetPropertiesAsync methods.
