how to read byte and write byte at the same time?

Question

how to read byte and write byte of a stream at the same time?

when I read some bytes it will give exception because I will write bytes to the stream and the Position of the stream will be the end of the stream I can not read any data.

Dear @mc,

After investigating the issue deeper, I found it's UWP app, it shouldn't use ASP.NET Core Tag.
Since I don't have the environment to test, the sample code should be like below, it can be built successfully, you can try it first.

 public class CameraStreamer
 {
     private BlockingCollection<byte[]> _buffer = new BlockingCollection<byte[]>();
     private const int BufferSize = 4096;

     public async Task StartRecordToStreamAsync(MediaCapture capture, MediaEncodingProfile profile, Socket socket)
     {
         var memoryStream = new MemoryStream();
         await capture.StartRecordToStreamAsync(profile, memoryStream.AsRandomAccessStream());

         Task.Run(() => ReadFromStreamToBuffer(memoryStream));

         Task.Run(() => SendFromBufferToSocket(socket));
     }

     private void ReadFromStreamToBuffer(MemoryStream stream)
     {
         while (true) 
         {
             if (stream.Length > BufferSize)
             {
                 byte[] buffer = new byte[BufferSize];
                 stream.Read(buffer, 0, BufferSize);
                 _buffer.Add(buffer);
             }
         }
     }

     private async Task SendFromBufferToSocket(Socket socket)
     {
         NetworkStream networkStream = new NetworkStream(socket);
         foreach (var buffer in _buffer.GetConsumingEnumerable())
         {
             await networkStream.WriteAsync(buffer, 0, buffer.Length);
         }
     }
 }
