Compressing WCF data for silverlight... help me clarify this

Question

Hello,

I've looked around and tried different solution, but none seems to work.... I've got a WCF service that right now sends huge xml over Http (binary)

The xml not compressed is 9,2MB

using SL3 binaryXML I reach 2,1MB

Using a sample application (web asp.net, not SL)  I tried Gzipping it and I'm around 500kb... the problem is I can't  find a working solution for WCF 3.5 SP1 and SL3 ...

I've seen this  and also this but they work on a previous version of WCF and compling them won't work anymore (I've got too much code to change and I'm not familiar with WCF channel structure)... I was wondering if there's a way of doing this in SL3 / WCF 3.5 ...

Either it's implemented at Endpoint level or Binding level I need the stub for SL and for WCF...

 

Thanks

Paolo

 Thanks Varshavman,

this is a commercial solution... do you know if there's something similar free? The price of that application is too much for what we need...

Have u got a sample of creating a silverlight-wcf channel implementation?

Thanks

I found an interesting article on this subject it comes with some code and it talks about compression

I hope this helps at least a little bit.....sorry I could not help more....
