take a compressed protobuf file (local), uncompress and then deserialize

gistfile1.cs

using (FileStream fs = new FileStream(location, FileMode.Open))
{
    using (GZipStream gz = new GZipStream(fs, CompressionMode.Decompress))
    {
        var result = Serializer.Deserialize<objectType>(gz);
        //work with result here...
    }
}
