How To Create Wcf Service In Visual Studio 2015

Creating and consuming a web service in WCF

Creating the WCF web service in Visual Studio

In this post I am using the WCF Web Service as an example, see this post for an example using using asmx:

Create a new Visual Studio project

In Visual Studio select the WCF installed template and create a new WCF Service Application:

Observe that a number of files are automatically created: IService1.cs, Service1.cs and Web.config, amongst others.,

We will modify the content of these for the purpose of this example:

Update the code in IService.cs file, as highlighted below. Notice that is does not do much since I like to keep these recipes extremely simple, understanding the process is more important.

IService1.cs

using System.Runtime.Serialization; using System.ServiceModel; using System.ServiceModel.Web;  namespace WcfService {    // NOTE: You can use the "Rename" command on the "Refactor" menu to change the interface name "IService1" in both code and config file together.    [ServiceContract]    public interface IService1    {       [OperationContract]       string GetData(int value);        [OperationContract]       CompositeType GetDataUsingDataContract(CompositeType composite);        [OperationContract]       [WebGet(UriTemplate = "/HelloWorld/")]       string HelloWorld();    }      // Use a data contract as illustrated in the sample below to add composite types to service operations.    [DataContract]    public class CompositeType    {       [DataMember]       public bool BoolValue { get; set; } = true;        [DataMember]       public string StringValue { get; set; } = "Hello ";    } }

Once the interface class is done do the concerete implementation in Service1.scv.cs:

Service1.scv.cs

using System;  namespace WcfService {    // NOTE: You can use the "Rename" command on the "Refactor" menu to change the class name "Service1" in code, svc and config file together.    // NOTE: In order to launch WCF Test Client for testing this service, please select Service1.svc or Service1.svc.cs at the Solution Explorer and start debugging.    public class Service1 : IService1    {       public string HelloWorld()       {          return "Hello world!";       }        public string GetData(int value)       {          return $"You entered: {value}";       }        public CompositeType GetDataUsingDataContract(CompositeType composite)       {          if (composite == null)             throw new ArgumentNullException(nameof(composite));          if (composite.BoolValue)             composite.StringValue += "Suffix";          return composite;       }    } }

Edit the Web.Config file. Be sure to include the 'endpointBehaviors' and 'add' elements as shown:

Web.Config

<?xml version="1.0"?>  <configuration>    <appSettings>     <add key="aspnet:UseTaskFriendlySynchronizationContext" value="true" />   </appSettings>   <system.web>     <compilation debug="true" targetFramework="4.5.2" />     <httpRuntime targetFramework="4.5.2" />     <httpModules>       <add name="ApplicationInsightsWebTracking"            type="Microsoft.ApplicationInsights.Web.ApplicationInsightsHttpModule, Microsoft.AI.Web" />     </httpModules>   </system.web>   <system.serviceModel>     <behaviors>       <serviceBehaviors>         <behavior>           <!-- To avoid disclosing metadata information, set the values below to false before deployment -->           <serviceMetadata httpGetEnabled="true" httpsGetEnabled="true" />           <!-- To receive exception details in faults for debugging purposes, set the value below to true.  Set to false before deployment to avoid disclosing exception information -->           <serviceDebug includeExceptionDetailInFaults="false" />         </behavior>       </serviceBehaviors>       <endpointBehaviors>         <behavior>           <webHttp />         </behavior>       </endpointBehaviors>     </behaviors>     <protocolMapping>       <add binding="webHttpBinding" scheme="http" />       <add binding="basicHttpsBinding" scheme="https" />     </protocolMapping>     <serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true" />   </system.serviceModel>   <system.webServer>     <modules runAllManagedModulesForAllRequests="true">       <remove name="ApplicationInsightsWebTracking" />       <add name="ApplicationInsightsWebTracking"            type="Microsoft.ApplicationInsights.Web.ApplicationInsightsHttpModule, Microsoft.AI.Web"            preCondition="managedHandler" />     </modules>     <!--         To browse web app root directory during debugging, set the value below to true.         Set to false before deployment to avoid disclosing web app folder information.       -->     <directoryBrowse enabled="true" />     <validation validateIntegratedModeConfiguration="false" />   </system.webServer>  </configuration>

Re-build your project.

To verify the service, right click on Service1.svc and select to view in a browser:

And see that the service created is as shown:

Consuming the WCF Web Service

Create a new Console Application in your solution

Set your project dependencies:

Set the reference to be used by the console application:

Set the Console app to be the start up application:

And finally modify Program.cs in order to consume the service:

using System; using WcfService;  namespace WebServiceConsumer {    internal static class Program    {       private static void Main()       {          var service = new Service1();           Console.Write(service.HelloWorld());       }    } }
