What is the easiest way to add compression to WCF in Silverlight?

Question

I have a silverlight 2 beta 2 application that accesses a WCF web service. Because of this, it currently can only use basicHttp binding. The webservice will return fairly

I didn't see a native way for WCF to do compression when doing a WCF project recently. I just used the System.IO.Compression namespace and made a quick compressor. Here's the code i used

public static class CompressedSerializer
{
    /// 

    /// Decompresses the specified compressed data.
    /// 
    /// 
    /// The compressed data.
    /// 
    public static T Decompress(byte[] compressedData) where T : class
    {
        T result = null;
        using (MemoryStream memory = new MemoryStream())
        {
            memory.Write(compressedData, 0, compressedData.Length);
            memory.Position = 0L;

            using (GZipStream zip= new GZipStream(memory, CompressionMode.Decompress, true))
            {
                zip.Flush();
                var formatter = new System.Runtime.Serialization.Formatters.Binary.BinaryFormatter();
                result = formatter.Deserialize(zip) as T;
            }
        }

        return result;
    }

    /// 

    /// Compresses the specified data.
    /// 
    /// 
    /// The data.
    /// 
    public static byte[] Compress(T data)
    {
        byte[] result = null;
        using (MemoryStream memory = new MemoryStream())
        {
            using (GZipStream zip= new GZipStream(memory, CompressionMode.Compress, true))
            {
                var formatter = new System.Runtime.Serialization.Formatters.Binary.BinaryFormatter();
                formatter.Serialize(zip, data);
            }

            result = memory.ToArray();
        }

        return result;
    }
}

then i just had my services take in a byte array as an input, like such

void ReceiveData(byte[] data);

Worked out well for me.
