How could I test a WCF service from browser

How could I test a WCF service from browser

• Reed14676

  Thanks for your replay.
  
  I had saw the static help page like ASMX in September CTP.
  But, are you sure can see the page in November CTP
  
  
  And, if I have a web browser application(WBA) that using XAML, how could it
  communicate with server via WCF service
  
  I heared about that the WBA can only communicate with server by calling Web
  Service, and the WCF service can publish as a web service by using
  basicHttpBinding/wsHttpBinding. But, how could I connect them
  
  Hope you can give me some advice.
  Best regards,
  Andy Law

  Hi Andy,
  
  You can always browse to your WCF service using IE.  This should bring up a static help page, similar to the one that you would see for ASMX.  From this page you can see the WSDL for the service, and get instructions on how to consume the service using svcutil.  Unfortunately, we don't currently support testing the service from the help page at this time.  You need to generate a proxy to test the service. 
  
  I will look into why you are seeing the error you describe.

  Thank you very much.
  
  Whit your help, I solve the problem.
  
  The following code only can test it in browsers on September CTP:
  
  Program.cs
  
  namespace MyWsHttpApp
  {
      class Program
      {
          static void Main(string[] args)
          {
              ServiceHost mathHost = new ServiceHost(typeof(MathServices));
              try
              {
                  mathHost.Open();
                  Console.WriteLine("Listening...");
                  Console.ReadLine();
              }
              finally
              {
                  mathHost.Close();
              }
          }
      }

  
      [ServiceContract(Name = "MathServices")]
      public interface IMathServices
      {
          [OperationContract]
          int Add(int a, int b);
      }

      public class MathServices : IMathServices
      {
          #region IMathServices Members

          public int Add(int a, int b)
          {
              return a + b;
          }

          #endregion
      }
  }
  
  app.config
  
  < xml version="1.0" encoding="utf-8" >
  <configuration>
    <system.serviceModel>
      <services>
        <service type="MyWsHttpApp.MathServices">
          <endpoint address="http://172.21.25.14:8877/MathServices"
          binding="basicHttpBinding"
          contract="MyWsHttpApp.IMathServices" />
        </service>
      </services>
    </system.serviceModel>
  </configuration>
  
  The following code can test it in browser on November CTP:
  
  Program.cs
  
  namespace MyWsHttpApp
  {
      class Program
      {
          static void Main(string[] args)
          {
              // Get base address from app settings in configuration
              Uri baseAddress = new Uri(ConfigurationManager.AppSettings["baseAddress"]);

              using (ServiceHost mathHost = new ServiceHost(typeof(MathServices), baseAddress))
              {
                  try
                  {
                      mathHost.Open();
                      Console.WriteLine("Listening...");
                      Console.ReadLine();
                  }
                  finally
                  {
                      mathHost.Close();
                  }
              }
          }
      }

  
      [ServiceContract(Name = "MathServices")]
      public interface IMathServices
      {
          [OperationContract]
          int Add(int a, int b);
      }

      public class MathServices : IMathServices
      {
          #region IMathServices Members

          public int Add(int a, int b)
          {
              return a + b;
          }

          #endregion
      }
  }
  
  app.config
  
  < xml version="1.0" encoding="utf-8" >
  <configuration>
   
    <appSettings>
      <!-- use appSetting to configure base address provided by host -->
      <add key="baseAddress" value="http://localhost:8877/MathServices" />
    </appSettings>
   
    <system.serviceModel>
      <services>
        <service type="MyWsHttpApp.MathServices">
          <endpoint address=""
                        binding="wsHttpBinding"
                        contract="MyWsHttpApp.IMathServices" />
        </service>
      </services>
     
    </system.serviceModel>
  </configuration>
  
  Thank Daniel and Mike for your help :-)

  The help page should work in the November CTP. Please ensure that you are specifying a BaseAddress in your constructor call to ServiceHost.
  
  With respect to the WBA, you should expose your WCF service using the BasicHttpBinding. You should then use the Add Web Reference functionality in Visual Studio to generate an ASMX-based proxy for communicating with that service.
  
  Hope that Helps,
