Hi ,

in my previous post I have explained how to interact WCF Services with Microsoft Dynamics CRM.
In this post I would like to explain how to invoke the Wcf services with CRM service using plugin c#.

• For calling external wcf services within our crm service, we can generate WCF Client Class similar to our early bound class generation.

Goto Visual Studio Tools –> Developer Command

• Use Svcutil.exe and map to the desired location where your client code has to get generated.

Type the following command : svcutil.exe followed by language type , Early Bound class Name.cs , Hosted Url of your WCF Application
svcutil.exe /language:cs /out:CreateLead.cs http://****:8081/Service1.svc

Generate WCF

Add the generated CreateLead.cs class in your application and the namespace reference in your plugin class file

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Microsoft.Xrm.Sdk;
using Microsoft.Xrm.Sdk.Query;
using System.Net;
using System.ServiceModel;
using CreateLead;  // Generated WCF Class
namespace Crm_Plugin
    public class WCF_Integration : IPlugin
        public void Execute(IServiceProvider serviceProvider)
            //Extract the tracing service for use in debugging sandboxed plug-ins.
            ITracingService tracingService =

            // Obtain the execution context from the service provider.
            IPluginExecutionContext context = (IPluginExecutionContext)

            // The InputParameters collection contains all the data passed in the message request.
            if (context.InputParameters.Contains("Target") && context.InputParameters["Target"] is Entity)
                // Obtain the target entity from the input parameters.
            Entity entity = (Entity)context.InputParameters["Target"];

               // Invoke  WCF SERVICE
                BasicHttpBinding myBinding = new BasicHttpBinding();
                myBinding.Name = "BasicHttpBinding_IService1";
                myBinding.Security.Mode = BasicHttpSecurityMode.None;
                myBinding.Security.Transport.ClientCredentialType = HttpClientCredentialType.None;
                myBinding.Security.Transport.ProxyCredentialType = HttpProxyCredentialType.None;
                myBinding.Security.Message.ClientCredentialType = BasicHttpMessageCredentialType.UserName;
                EndpointAddress endPointAddress = new EndpointAddress("http://******:8080/Service1.svc");

                ChannelFactory<IService1> SerFactor = new ChannelFactory<IService1>(myBinding, endPointAddress);
                IService1 chanl = SerFactor.CreateChannel();

// Passing Parameter to the Wcf Class CreateLead
string Result =chanl.CreateLead(entity.GetAttributeValue<string>("firstname").ToString(), entity.GetAttributeValue<string>("lastname").ToString(), entity.GetAttributeValue<string>("emailaddress1").ToString());

* Note ,
i have registered my plugin in pre create Contact Entity .
Passing [ First Name , Last Name , Email Address ] 3 parameters to out CreateLead WCF Method .
