Reference WCF Web Service & Client to transfer a file

This is a really simple exercise that has had me banging my head on the wall for a week. I have all the systems/sw listed at the end already. The solution must work within that environment.


NOTE: Because this is so simple, I will chose the developer based on their written approach to the problem IN THEIR BID. Please give me a few sentences IN YOUR BID describing your approach to marshaling these objects. Thank you! :)



1. A VS2008 solution that has a project for a windows client and another for the IIS server web service.

2. The win client is nothing but a simple test client that sends a test class (can be anything) to the web service, and receives a zip file in return.

3. The web service is just a test service to receive the test class and send a file to the client.

4. Yes, it is that simple.


1. The client has a button that the user will click.

2. The client then converts an instance of a simple test class into XML in memory.

3. The client then invokes the test web service (WCF), giving this test class (as an XML "file") as a parameter.

4. The service receives the XML and converts it back to an instance of the test object.

5. The service then loads a file on the local file system (any file-doesn't matter) into memory.

6. The service then takes an instance of another test class and converts it to XML in memory.

7. The service then zips the 2 "files" together in memory to form a single file in memory.

8. The service then sends this file as it's response to the call to the web service.

9. The client takes this file/stream from the web service.

10. The client then unzips this single "file" into it's 2 components (XML and file).

11. The client writes the file to the local disk, giving it an arbitrary name ([url removed, login to view]).

12. Finally, the client converts the XML received into an instance of the class it started out as on the server.










-All class types can be made up, and have just one attribute, if you like.

-The web service can be called anything you like.

-This is just a reference project to demonstrate how to do it. I will use this reference job to make more practical applications.

-I don't care if the solution is a straight service, or a WCF service library (DLL) is utilized. Your call.
