Invoke string silverlight

Invoke string silverlight

I have a problem with invoking string, I am creating silverlight application:

This is my DomainService:

// TODO: Create methods containing your application logic. [EnableClientAccess()] public class DomainService1 : DomainService {      LicensedClass validation = new LicensedClass();      [Invoke]     public string licenseValidation()     {           return validation.Validation();      }       [Invoke]     public string licenseInformation()     {          return validation.LicFile();       }  } 

}

And this is my Client Side class:

   public partial class MainPage : UserControl {       DomainService1 domain = new DomainService1();     public MainPage()     {         InitializeComponent();     }     public void CheckText() {         InvokeOperation<string> operation3 = domain.licenseInformation();         operation3.Completed += (x, y) =>         {             if (!operation3.HasError)             { textBox2.Text = operation3.Value; }             else { textBox1.Text = "error"; }           };         } 

but when I run my app nothing happens, text boxes are just blank. Any suggestions?
