During the creation of an auto-generated WCF domain service class based off entity framework, a file that contains the metadata for the EF classes is also created. In this file, I've had to add the [Include()] attribute to a number of classes so that I can include these properties during WCF calls. My problem is, I sometimes have to changed the data model. This requires that I remove the entire metadata file along with the domain services file, and regenerate the entire thing and then go back and add the [Include()] attributes back to the correct properties. Is there a better way to do this? Is there a way to keep the [Include()] attributes in a separate file so that I don't have to continuously go back and add them in?
