My requirement is iam working on Windows8 App, i need to send an Registration XML file to MVC4 Application which is acting as a service. Windows8 acts a client and MVC4 acts as Server. In server there will be already an Registration xml file, i need to check with that xml file any Username is already exist or not. If exits then i need send message that "username already exists please chosse other username." If not then I have to add a extra node in the registration.xml at server.
So now i need the Code how to send an XML file as an object in Windows8 App and how to receive/accept xml file in MVC4 Application.
