If you are implementing a WCF client it is often common to wrap that client in a Using statement or call dispose on it - however this way of working with it can cause a variety of problems. From a proven practices point of view, you can use the wcf client snippet which produces 20 lines of code which has:

The try...catch correctly implemented
All likely exceptions listed in the catch statements
Correct placement of the close call in the try block
Correct placement of the abort calls in the catch statements

Installation is as easy as saving to the correct folder which changes depending on your version of Visual Studio:
