NetworkStream stream =new NetworkStream(socket);

stream.AsRandomAccessStream() throws exception

    The remarks in NetworkStream include the following sentence.

    The NetworkStream does not support random access to the network

    If you want to use it, you can use AsInputStream or AsOutputStream instead of AsRandomAccessStream.

    The network data stream does not support random access by design as @gekka answered. But you can copy it to a stream that does support random access for example MemoryStream. See the Example: Convert .NET Framework to Windows Runtime random-access stream.
