Library name and version

Azure.Storage.Blobs 12.12.0

Query/Question

Hi,

I am trying to use the Azure Blob Storage SDK to list the contents of a directory on Xamarin.iOS.

The following code fails.

            var blobClientOptions = new BlobClientOptions(BlobClientOptions.ServiceVersion.V2021_06_08);
            try
            {
                HttpPipelinePolicy policy = new AuthTokenHttpPipelinePolicy(restApiClient);
                blobClientOptions.AddPolicy(policy, HttpPipelinePosition.PerRetry);
                blobClientOptions.AddPolicy(new ApimTracingHttpPipelinePolicy(restApiClient), HttpPipelinePosition.PerRetry);
                blobClientOptions.AddPolicy(new SasTokenHttpPipelinePolicy(sasCache), HttpPipelinePosition.PerRetry);
            } catch(Exception e)
            {
                Console.WriteLine(" Caught in exception, " + e.ToString());
            }

But the line blobClientOptions.AddPolicy(policy, HttpPipelinePosition.PerRetry) fails on Xamarin.iOS. Its working fine on Xamarin.Android.

This is the exception that I am getting.

Environment

Xamarin.iOS

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

BlobClientOptions inherits the AddPolicy method from ClientOptions from the Azure.Core package.

Adding tag for Core

Also could you define what's occurring in your custom class for AuthTokenHttpPipelinePolicy, that doesn't seem like that belongs to Azure.Core or any of our other SDKs

@bonniemathew: I'm unable to reproduce this with the latest VS for Mac, XCode, and Blob Storage package. As @amnguye mentioned, it would be very helpful to understand the code in your AuthTokenHttpPipelinePolicy implementation.
