HOW TO AVOID TOO MANY OBJECT CREATION IN Silverlight enabled WCF service,

in silverlight enabled wcf service,

i have used 4 classes, each class contain minimum 10 function,

if create object each class occupy more space right.

how avoid that?

example:
[servicecontract(namespace = "")]
[aspnetcompatibilityrequirements(requirementsmode = aspnetcompatibilityrequirementsmode.allowed)]
   
    public class service1
    { 

        public class1 objc1 = new class1();
        public class2 objc2 = new class2();
        public class3 objc3 = new class3();
        public class4 objc4 = new class4();

        [operationcontract]
        public void dowork()
        {
            // add operation implementation here
            return;
        }

 

     use single object perform task ,

     if it's possible , kindly send sample link or code.
