Load PDF From Azure

[Joel]

I had this working at one point for a demo... maybe something changed?  But, now I'm baking this into my site for real and pulling a PDF from Azure.  I verify that I'm getting the stream.  Do I have the correct return type?

if (currentContainer.Container == null)
{
    var containerResponse =
        await containerClient.GetAsync(
            currentContainer.ContainerId);

    if (containerResponse.IsSuccess)
    {
        currentContainer.Container =
            containerResponse.Result;
    }
}

if (currentContainer.Container != null)
{
    CloudStorageAccount storageAccount =
        CloudStorageAccount.Parse(
            Glossary.Container.StorageAccountUrl);

    CloudBlobClient blobClient =
        storageAccount.CreateCloudBlobClient();

    CloudBlobContainer container =
        blobClient.GetContainerReference(
            currentContainer.Container.Name);

    if (await container.ExistsAsync())
    {
        CloudBlockBlob blob =
            container.GetBlockBlobReference(
                currentContainer.Path);

        if (await blob.ExistsAsync())
        {
            // pull the zip file into memory
            // load the zipFileStream from the blob
            MemoryStream stream = new MemoryStream();
            await blob.DownloadToStreamAsync(stream);
            return new FileStreamResult(stream, "application/pdf");
        }
        else
        {
            throw new Exception("File not found in Azure container for this record");
        }
    }
    else
    {
        throw new Exception(
            $"Unable to capture Azure container: {currentContainer.Container.Name}");
    }
}
else
{
    throw new Exception($"Unable to capture recorded container for this file.");
}

Hello Joel,

Yes, return new FileStreamResult(stream, "application/pdf"); is a valid return type. What is the exception you get when you try to load a pdf  in the PDFViewer this way?
