For us, WCF is used for SOAP and Web API for REST. I wish Web API supported SOAP too. We are not using advanced features of WCF. Here is comparison from MSDN:
You just need to add [FromUri] before parameter, looks like: GetCategories([FromUri] int[] categoryIds) And send request: /Categories?categoryids=1&categoryids=2&categoryids=3
