I have a client's wsdl and xsds files for java webservices. I am using svcutil (XmlSerializer) to generate the client side proxy classes. I had to make a few tweaks to the wsdl's (which I told the client about) to make svcutil work but now it generates one 11.2MB file which compiles into a 3.7MB dll. Is there any way to have svcutil split out the service classes into seperate files or split out the data classes into their own file? It seems that the only way I can get the proxy service classes to share the same data classes is by generating all of the code at once, which produces the giant file.
