3 Ways to generate proxy for WCF Service – CodeProject

In Windows Communication Foundation, for a client application to communicate with a WCF Service, we have following options:
Using ChannelFactory Generating Proxies
I have already discussed about difference between ChannelFactory and Proxies in one of my previous WCF Tutorial on this blog. In this article, we will focus only on multiple ways to generate proxy in Windows Communication Foundation.
“A Proxy in Windows Communication Foundation is a class that enables client applications to communicate with a service by sending and receiving messages. It actually encapsulates a number of service details like service path, service implementation technology, platform being used, communication protocol etc. as well as all the methods (signature only) of the Service Contract. ”
Windows Communication Foundation supports following three ways to generate proxy for a WCF Service.
Adding Service Reference Implementing ClientBase Using Tool i. e.
So, in this WCF Tutorial, we will carry out all three possible ways to generate proxy for a WCF service. Let’s create a simple WCF Service first.
Create WCF Service
I have already provided implementation for a new WCF Service creation and hosting in a separate WCF Tutorial here. Please follow the steps to create a “StudentService” and host in a console application.
Option 1: Generate Proxy Adding Service Reference
Implementation of generating proxy by adding a service reference is also available here for the same WCF service i. e. “StudentService”.
Option 2: Generate Proxy by implementing ClientBase class
Generating proxy by using ClientBase class option has an advantage that it creates proxy at run time, so it will accommodate service implementation changes. Let’s follow the steps to generate proxy.
Add a Client Project to solution named as “ClientApp2″ that is basically a Console Application.
Add reference of StudentService Project to ClientApp2. Add following proxy class using ClientBase as:
public class StudentServiceProxy: ClientBase, IStudentService
{
public string GetStudentInfo(int studentId)
return tStudentInfo(studentId);}}
Note: Don’t forget to add “using StudentService” to class.
Following is the code for class in ClientApp2. We are using above created proxy class to communicate with WCF Service “StudentService“.
class Program
static void Main(string[] args)
StudentServiceProxy myclient;
myclient = new StudentServiceProxy();
int studentId = 1;
Console. WriteLine(“Calling StudentService with StudentId = 1….. “);
Console. WriteLine(“Student Name = {0}”, tStudentInfo(studentId));
adLine();}}
Note: Don’t forget to add “using rviceModel” to class.
file will have following configuration:











Now, when we run the client application, we will receive the following same output as we get in earlier option “Adding Service Reference”.
Option 3: Generate Proxy by using Tool
Let’s generate proxy by using third option i. Tool by following step by step approach.
Add a Client Project to solution named as “ClientApp3″ that is basically a Console Application.
Our WCF Service must be running, so let’s run our service.
Open Visual Studio Command Prompt and generate proxy using tool as follows:
svcutil localhost:4321/StudentService /
It will generate a new class “”.
Add newly created proxy class to our client application “ClientApp3″. Call WCF Service using proxy class as:
StudentServiceClient myclient;
myclient = new StudentServiceClient();
When we run the application, it will call StudentService method getStudentInfo and generate the same output as we received in other options.
Hopefully, this WCF tutorial will be helpful to understand concepts of WCF Proxy and different ways to generate it.

It requires creating Proxies or using ChannelFactory. Proxies create after hosting the service. There are two ways to communicate with client application in Windows Communication Foundation. First one is using the ChannedFactory and other one is creating proxies classes. Today you will learn focus only for creating Proxy. Actually Proxy is a class in WCF that is used to communicate with client application. We can simply get the entire configuration through the proxy class. There is no need to do extra effort to generate the configuration setting for the client. Proxy class used when you think that your service must be loosely coupled. If you make any changes in service then client must be rebuild. There are the following details inside the proxy class. It stores the path of the service. Protocol which is using to communicate with client. It contains service implementation. It contains the signature for the service contract. There are the following restrictions with Proxy Class. Proxy class does not work with read only or write only properties, It should be getter and setter. Proxy class expose only ServiceContract, we cannot expose any other contract or method which is not inside the Service Contract. Class Constructor does not expose by proxy class. There are different options to generate the proxy class for the WCF Service. By “Add Service Reference” from Visual Studio. Using Utility. Implementing ClientBase class. Step 1: By “Add Service Reference” from Visual Studio In Visual Studio, we can add the service reference inside the References. Be sure your service should be running before going to make reference of the service. So, once your service is running, we can add the service reference in client application. Firstly, make sure your service is running. For this demo I have hosted my service and it is running. To add the service reference into client application, Right click on References and choose Add Service Reference, It will open a Add Service Reference window where you can pass your service URL to access the service. In my case, here’s the service URL. Add the service URL into Address section and click Go. It will show your service into Services section and all methods into Operation Section. You need to provide the suitable namespace for the service reference and good to go. After clicking Ok, it will add the service reference with required file into your client project inside the Service References folder. You can use the following way to call the service into client application. So, finally we have generated the proxy class from Visual Studio Add Service Reference Option. Step 2: Using Utility. is a tool for service utility. Using this you can also generate the proxy into client application for the service. Before going to create the proxy for the service, please make sure your service or host service is running. Open Visual Studio Command Prompt where client application is going to run and generate the proxy class and configuration for the service. You can pass the proxy class name as / It will generate two new files for us. One is our proxy class “” and other one is “”; [neratedCodeAttribute(“rviceModel”, “4. 0. 0”)] [rviceContractAttribute(ConfigurationName = “IMathService”)] public interface IMathService { [rviceModel. OperationContractAttribute(Action = “, ReplyAction = “)] int Add(int num1, int num2); [rviceModel. OperationContractAttribute(Action = “, ReplyAction = “)] < int > AddAsync(int num1, int num2); [rviceModel. OperationContractAttribute(Action = “, ReplyAction = “)] int Subtract(int num1, int num2); [rviceModel. OperationContractAttribute(Action = “, ReplyAction = “)] < int > SubtractAsync(int num1, int num2); [rviceModel. OperationContractAttribute(Action = “, ReplyAction = “)] int Multiply(int num1, int num2); [rviceModel. OperationContractAttribute(Action = “, ReplyAction = “)] < int > MultiplyAsync(int num1, int num2);} [neratedCodeAttribute(“rviceModel”, “4. 0”)] public interface IMathServiceChannel: IMathService, rviceModel. IClientChannel {} [buggerStepThroughAttribute()] [neratedCodeAttribute(“rviceModel”, “4. 0”)] public partial class MathServiceClient: ientBase < IMathService >, IMathService { public MathServiceClient() {} public MathServiceClient(string endpointConfigurationName): base(endpointConfigurationName) {} public MathServiceClient(string endpointConfigurationName, string remoteAddress): base(endpointConfigurationName, remoteAddress) {} public MathServiceClient(string endpointConfigurationName, rviceModel. EndpointAddress remoteAddress): base(endpointConfigurationName, remoteAddress) {} public MathServiceClient(nding binding, rviceModel. EndpointAddress remoteAddress): base(binding, remoteAddress) {} public int Add(int num1, int num2) { return (num1, num2);} public < int > AddAsync(int num1, int num2) { return dAsync(num1, num2);} public int Subtract(int num1, int num2) { return btract(num1, num2);} public < int > SubtractAsync(int num1, int num2) { return btractAsync(num1, num2);} public int Multiply(int num1, int num2) { return ltiply(num1, num2);} public < int > MultiplyAsync(int num1, int num2) { return ltiplyAsync(num1, num2);}} Through the following way you can call this proxy class. So, finally we have created the proxy class using Step 3: Implementing ClientBase class. Firstly, create a class named with “” and inherited ClientBase. You need to add rviceModel namespace for this implementation. Add the implementation to use the service rviceModel; using MathServiceLibrary; namespace MathClient { class MathServiceProxy: ClientBase < IMathService >, IMathService { public int Add(int num1, int num2) { return (num1, num2);} public int Subtract(int num1, int num2) { return btract(num1, num2);} public int Multiply(int num1, int num2) { return ltiply(num1, num2);}}} You can call this proxy class into your client application as in the following way. So, finally we have achieved all three ways to generate the proxy class for the wcf service. Thanks for reading this article, hope you enjoyed it.
