How to Create a WCF Service library

• Add the WCF Service library

• Add the service host project to the solution

• Add the  Business Objects class library to the solution
• Add the Business Logic class library to the solution 
• Add the Data Access layer class library to the solution 
• Add the DTObjects class library to the solution
• Add the DTOStudent  Class to the DTObjects project
  
  
  • Add the System.Runtime.Serialization as reference to the project 
  • Decorate the Data Contract as DTOStudent Class and add few properties and decorate it as data member
  
  
  
  
  

•   Add the Student to the business object and add the class properties

• Add BOAssembler class to the business logic and add StudentBusinesObjects Project  and DTOobjects project as references
• Implement the AssembleStudentBO method to the BOAssembler class

• Add DTOAssembler  class and Implement the AssembleStudentDTO method

• Implement the Data Access layer
• Add the connection string as the key of the web.configration file using the settings file modifications

• 
  
  
  
  
  
  
  
  
  
  
  
  

• Change the key name to student
• if you open the web.config file you can see the changes what are made by adding the connection string key

•  Add the  IDALDBConnection interface to the project and add the signatures

• Add the DbConnection Class to the DAL and add the DbConnection and DbTransaction abstract class members to the DBConnection Class 

•  Implement  the connection string method
  
  
  
  
  
• implement the ExecuteNonQuery method

• implement the Execute DataSet method
  
  
  
  
  
  
  
• implement the business object Student class methods and add the constructor
  implement the add Student method 
  
  
  

• implement the Get Student method 

• Add the IStudentService Interface to Business Logic layer and add the two methods

• implement the method in the StudentService class

• Implement the IStudentManagementService interface to StudentServiceLibrary
• Decorate the service as ServiceContract  and methods as OperationContract

• Implementation of the StudentManagementService class

• Implementation of the StudentServiceHost layer

• Rename the SVC class to the StudenService and delete the cs class of the SVC file
• Remove the CodeBehind tag and set the Service="StudentServiceLibrary.StudentManagementService"
  
• Open the StudentServiceLibrary app.config file using the WCF editor and change the service name to StudentServiceLibrary.StudentManagementService.

• Now Change the end point  basicHttpBinding contract property to the
  " StudentServiceLibrary.IStudentManagementService "
  
  
  
  
  
   
• Now open the App.config file and copy the <services> tag element  and paste in to the Web.config file 
  
  
  
  
  
• Now u can successfully  run the service
  
  
  
  
  
• Add the student to the database and Get the all student add by the service
