How about this.

public class ObservableFileStream : FileStream
{
    private Action _callback;

    public ObservableFileStream(String fileName, FileMode mode, Action callback) : base(fileName, mode)
    {
        _callback = callback;
    }

    public override void Write(byte[] array, int offset, int count)
    {
        _callback?.Invoke(Length);
        base.Write(array, offset, count);
    }

    public override int Read(byte[] array, int offset, int count)
    {
        _callback?.Invoke(Position);
        return base.Read(array, offset, count);
    }
}

public class Test
{
    private async void Upload(String filePath, CloudBlockBlob blob)
    {
        ObservableFileStream fs = null;

        using (fs = new ObservableFileStream(filePath, FileMode.Open, (current) =>
        {
            Console.WriteLine("Uploading " + ((double)current / (double)fs.Length) * 100d);
        }))
        {
            await blob.UploadFromStreamAsync(fs);
        }
    }
}
