WCF Streaming Big file

How can I send the service a ref of a big file on the cliet's computer by a stream object and then start download piece by piece it from the client's computer (I decide how much MB I transfer every sec)? Do I have any limitations when I use it?

IIS doesn't support streaming - it buffers the whole request.

CodeProject article: WCF 4.5 fixes this

Until then, if you use IIS, the whole file will be stored in server memory before it is passed to your service.

The solution for now is to send the file in chunks - each chunk sent in a separate service call.

This would also help with your bandwidth throttling. This is not built into WCF - you have to do it yourself. You can throttle each chunk either on the client or on the server.
