_ServerAccess Source Files
It contains a small helper class that provides a convenient starting point for encapsulating the access to your server from within your client app. Once created, this file becomes "yours", and you will most likely expand it (significantly) to expose functionality more specific to your concrete project.
ServerAccess class is merely a suggestion and an assistance to get you started, you can feel free to simply remove the file from your project, or rewrite it vastly, if you want to structure your server access differently within the client app.
Please refer to the Connecting to a Remoting SDK Server topic for more details.
