Hi There,

I have create a small applications that uses a webservice that allows you to stream a file to or from the web service.

Streaming is enabled on the web service. Here is 2 links if you would want read up on it:

Hello alhambraeidos,

Thank you for using our free Microsoft All-In-One Code Framework Sample Request Service!

Your sample request is about how to use the WCF Service to send the big Files. If I misunderstood your requirement, please feel free to let me know.

You can refer the MariusVanBelkum’s link, and if you want the sample, you can refer the following link: http://code.msdn.microsoft.com/Streaming-Photo-OData-7feb9239.
This sample demonstrates how to use WCF Data Services to implement an OData service that uses a streaming provider to store and retrieve image files.

Please let us know if this sample is helpful to you.

Thanks and have a great day!
