WCF proxy creation

Question

Hello,
I have the client application to consume WCF service

class Test  
{  
    static void Main()  
    {  
        TestService client = new TestService("netTCP");  
  
        // Use the 'client' variable to call operations on the service.  
  
        // Always close the client.  
        client.Close();  
    }  
  
  private void ToDo(string s)  
         {  
           var client = new TestService("netTCP");  
                
         }  
  
}  
  
  

Which is the correct way to create the client ?
When to close the client and when is better to create the proxy?

Hi @B M-A ,

1. You can create a client in several ways: Service Reference, Svcutil.exe, Channel Factory, Client Base. You may pick and choose what works for you. Here is the example. https://learn.microsoft.com/en-us/dotnet/framework/wcf/wcf-client-overview.
2. You should close it as recommended. And if you are using async methods, you should close it after the call completes. And remember to add try and catch on close in order to deal with exceptions.
