Creating WCF Client in Windows Mobile

Setelah satu bulan tidak menulis di blog (dikarnakan keikut-sertaan saya dalam mengurus putri pertama saya yang baru lahir :-) ) , maka pada kesempatan kali ini saya akan sedikit berbagi tulisan mengenai pembuatan “WCF Client di Windows Mobile”. Meskipun windows phone 7 sudah diluncurkan pada tahun ini tetapi saya tetap mengutak-atik mengenai pengembangan windows mobile 6.5 kebawah yang tentunya dengan .Net Compact Frameworknya. Untuk penjelasan WCF dengan konsep ABC (Address, Binding, Contract ) tidak saya bahas ulang. Berikut ini langkah-langkahnya:

I. Pembuatan WCF Service :

1. Buka VS 2008 anda.

2. Buat project “WCF Service Library” baru kemudian beri nama dengan WCFLanguage (disini memakai  C#)

3. Kemudian kopikan code dibawah ini di file app.config project tersebut

    Catatan : - Address Host saya gunakan : http://192.168.10.68:8282/WCFLanguage/Language

                   - EndPoint  : <endpoint address="mex"   binding="mexHttpBinding"  contract="IMetadataExchange"/>

                   - Ganti sesuai settingan anda

   1: <?xml version="1.0" encoding="utf-8" ?>

   2: <configuration>

   3:   <system.web>

   4:     <compilation debug="true" />

   5:   </system.web>

   6:   <!-- When deploying the service library project, the content

   7: of the config file must be added to the host's app.config

   8: file. System.Configuration does not support config files

   9: for libraries. -->

  10:   <system.serviceModel>

  11:     <services>

  12:       <service name="WCFLanguage.Language"

  13:       behaviorConfiguration="WCFLanguage.LanguageBehavior">

  14:         <host>

  15:           <baseAddresses>

  16:             <add baseAddress ="http://192.168.10.68:8282/WCFLanguage/Language" />

  17:           </baseAddresses>

  18:         </host>

  19:         <!-- Service Endpoints -->

  20:         <!-- Unless fully qualified, address is relative to

  21: base address supplied above -->

  22:         <endpoint address =""

  23:         binding="basicHttpBinding"

  24:         contract="WCFLanguage.ILanguage" />

  25:         <!--

  26: Upon deployment, the following identity element

  27: should be removed or replaced.

  28: -->

  29:         <!-- Metadata Endpoints -->

  30:         <endpoint address="mex"

  31:         binding="mexHttpBinding"

  32:         contract="IMetadataExchange"/>

  33:       </service>

  34:       

  35:     </services>

  36:     <behaviors>

  37:       <serviceBehaviors>

  38:         <behavior name="WCFLanguage.LanguageBehavior">

  39:           <!-- To avoid disclosing metadata information,

  40: set the value below to false and remove the metadata

  41: endpoint above before deployment -->

  42:           <serviceMetadata httpGetEnabled="True"/>

  43:           <!-- To receive exception details in faults for

  44: debugging purposes, set the value below to true.

  45: Set to false before deployment to avoid disclosing

  46: exception information -->

  47:           <serviceDebug includeExceptionDetailInFaults="False" />

  48:         </behavior>

  49:  

  50:       </serviceBehaviors>

  51:     </behaviors>

  52:   </system.serviceModel>

  53: </configuration>

4. Ganti nama file IService1.cs ke ILanguage.cs untuk pembuatan Interface yang digunakan dalam pendefinisian contract Language.

    Kemudian ketikkan code berikut ini.

   1: using System;

   2: using System.Collections.Generic;

   3: using System.Linq;

   4: using System.Runtime.Serialization;

   5: using System.ServiceModel;

   6: using System.Text;

   7:  

   8: namespace WCFLanguage

   9: {

  10:     

  11:     [ServiceContract]

  12:     public interface ILanguage

  13:     {

  14:         [OperationContract]

  15:         string[] GetAllLanguages();

  16:         [OperationContract]

  17:         string ChooseLanguage(string Code);

  18:         

  19:     }

  20:  

  21:    

  22:     [DataContract]

  23:     public class DataLanguage

  24:     {

  25:         string strLanguage = "";

  26:         string strResult = "";

  27:  

  28:         [DataMember]

  29:         public string StringLanguage

  30:         {

  31:             get { return strLanguage; }

  32:             set { strLanguage = value; }

  33:         }

  34:  

  35:         [DataMember]

  36:         public string StringResult

  37:         {

  38:             get { return strResult; }

  39:             set { strResult = value; }

  40:         }

  41:     }

  42: }

5. Ganti nama file Service1.cs menjadi Language.cs kemudian ketikkan code berikut ini.

   1: using System;

   2: using System.Collections.Generic;

   3: using System.Linq;

   4: using System.Runtime.Serialization;

   5: using System.ServiceModel;

   6: using System.Text;

   7:  

   8: namespace WCFLanguage

   9: {

  10:     // NOTE: If you change the class name "Service1" here, you must also update the reference to "Service1" in App.config.

  11:     public class Language : ILanguage

  12:     {

  13:         public string[] GetAllLanguages()

  14:         {

  15:             string[] strLanguages = new string[3];

  16:             strLanguages[0] = "C#";

  17:             strLanguages[1] = "F#";

  18:             strLanguages[2] = "VB .Net";

  19:  

  20:             return strLanguages;

  21:         }

  22:         public string ChooseLanguage(string Code)

  23:         {

  24:             string strResult = "";

  25:             if (Code == "C#")

  26:             {

  27:                 strResult = "Amazing language";

  28:             }

  29:             else if (Code == "F#")

  30:             {

  31:                 strResult = "Interesting New Language";

  32:             }

  33:             else if (Code == "VB .Net")

  34:             {

  35:                 strResult = "Familiar Language";

  36:             }

  37:             return strResult;

  38:         }

  39:  

  40:         public DataLanguage YourFavLanguage (string Code)

  41:         {

  42:             var L = new DataLanguage();

  43:             L.StringLanguage  = Code;

  44:  

  45:             string strResult = "";

  46:             strResult = ChooseLanguage(L.StringLanguage);

  47:             L.StringResult = strResult;

  48:             return L;

  49:  

  50:         }

  51:     }

  52: }

6. Jalankan project tersebut maka akan tampil seperti berikut. Service WCFLanguage siap diimplementasikan.

II. Pembuatan WCF Client di Windows Mobile.

1. Download .Net Compact Framework Power Toys 3.5 disini, kemudian install.

2. Pada project tadi pilh menu File –> Add –> New Project.

3. Pilih SmartDevice (C#), kemudian simpan dengan nama WMClient.

4. Target Device ke Windows Mobile 6

5. Tambahkan namespace System.Runtime.Serialization dan System.ServiceModel melalui Add References

6. Kopikan file WCFLanguage.dll (di folder project anda) ke path “C:\Program Files\Microsoft.NET\SDK\CompactFramework\v3.5\bin”

7. Jalankan Service WCFLanguage tadi (Point I.6)

8. Buka Command Prompt kemudian ketikkan “CD C:\Program Files\Microsoft.NET\SDK\CompactFramework\v3.5\bin”

9. Ketikkan di Command prompt tadi seperti berikut “NETCFSvcUtil.exe http://192.168.10.68:8282/WCFLanguage/Language”

10. Ketikkan di Command prompt seperti berikut “NETCFSvcUtil.exe WCFLanguage.dll”

11. Ketikkan di Command prompt seperti berikut “NETCFSvcUtil.exe *.wsdl *.xsd”

12. Kembali ke project WMClient anda, kemudian buat tampilan seperti berikut ini.

13. Pilih menu Project –> Add Existing Item. Kemudian buka path “C:\Program Files\Microsoft.NET\SDK\CompactFramework\v3.5\bin”

      Tambahkan file Language.cs dan CFClientBase.cs ke project tersebut.

13. Ketikkan di code berikut ini di Form1.cs

   1: using System;

   2: using System.Linq;

   3: using System.Collections.Generic;

   4: using System.ComponentModel;

   5: using System.Data;

   6: using System.Drawing;

   7: using System.Text;

   9: using System.Runtime.Serialization;

  10: using System.ServiceModel;

   8: using System.Windows.Forms;

  11:  

  12:  

  13: namespace WMClient

  14: {

  15:     public partial class Form1 : Form

  16:     {

  17:         public Form1()

  18:         {

  19:             InitializeComponent();

  20:         }

  21:  

  22:         private void button1_Click(object sender, EventArgs e)

  23:         {

  24:  

  25:             var l = new LanguageClient();

  26:             MessageBox.Show(l.ChooseLanguage(cboLanguage.SelectedItem.ToString()));

  27:  

  28:             

  29:            

  30:         }

  31:  

  32:         private void Form1_Load(object sender, EventArgs e)

  33:         {

  34:             var l = new LanguageClient();

  35:             string[] strLang = l.GetAllLanguages();

  36:  

  37:             cboLanguage.Items.Clear();

  38:             foreach (string str in strLang)

  39:             {

  40:                 cboLanguage.Items.Add(str);

  41:             }

  42:             cboLanguage.SelectedIndex = 0;

  43:             l = null;

  44:  

  45:         }

  46:  

  47:        

  48:     }

  49: }

14. Jalankan Service WCFLanguage tadi (Point I.6)

15 Kemudian jalankan pula Project SmartDevice WMClient melalui Klik Kanan –> Debug –> Start New Instance

16. Hasil akhir seperti berikut ini.
