try this

    public class DeCompressedContent : HttpContent
{
    private HttpContent originalContent;
    private string encodingType;

    /// 

    /// 
    /// 
    /// 
    /// 
    public DeCompressedContent(HttpContent content, string encodingType)
    {

        if (content == null) throw new ArgumentNullException("content");
        if (string.IsNullOrWhiteSpace(encodingType)) throw new ArgumentNullException("encodingType");

        this.originalContent = content;
        this.encodingType = encodingType.ToLowerInvariant();

        if (!this.encodingType.Equals("gzip", StringComparison.CurrentCultureIgnoreCase) && !this.encodingType.Equals("deflate", StringComparison.CurrentCultureIgnoreCase))
        {
            throw new InvalidOperationException(string.Format("Encoding {0} is not supported. Only supports gzip or deflate encoding", this.encodingType));
        }

        foreach (KeyValuePair> header in originalContent.Headers)
        {
            this.Headers.TryAddWithoutValidation(header.Key, header.Value);
        }

        this.Headers.ContentEncoding.Add(this.encodingType);
    }

    /// 

    /// 
    /// 
    /// 
    /// 
    /// 
    protected override Task SerializeToStreamAsync(Stream stream, TransportContext context)
    {
        var output = new MemoryStream();

        return this.originalContent
            .CopyToAsync(output).ContinueWith(task =>
            {
                // go to start
                output.Seek(0, SeekOrigin.Begin);

                if (this.encodingType.Equals("gzip", StringComparison.CurrentCultureIgnoreCase))
                {
                    using (var dec = new GZipStream(output, CompressionMode.Decompress))
                    {
                        dec.CopyTo(stream);
                    }
                }
                else
                {
                    using (var def = new DeflateStream(output, CompressionMode.Decompress))
                    {
                        def.CopyTo(stream);
                    }
                }

                if (output != null)
                    output.Dispose();
            });


    }

    /// 

    /// 
    /// 
    /// 
    /// 
    protected override bool TryComputeLength(out long length)
    {
        length = -1;

        return (false);
    }
