so .Net 4 added named and optional parameters which are pretty sweet. I don't need to make as many 1 line overload methods.
Will that work over WCF?

Named arguments enable you to specify an argument for a parameter by matching the argument with its name rather than with its position in the parameter list. Optional arguments enable you to omit arguments for some parameters. Both techniques can be used with methods, indexers, constructors, and delegates.
A mandatory parameter must be explicitly given on the command-line, otherwise an error message will be printed to prompt the user to re-enter the command. If an optional parameter is not specified, the default is used. Note: Mandatory parameters have a default value for use in the GUI.
Named parameters are often used in conjunction with optional parameters. Without named parameters, optional parameters can only appear at the end of the parameter list, since there is no other way to determine which values have been omitted.
By Params Keyword: You can implement optional parameters by using the params keyword. It allows you to pass any variable number of parameters to a method. But you can use the params keyword for only one parameter and that parameter is the last parameter of the method.
WSDL cannot describe optional parameters, so the answer is "no".
