how to retrieve entity on update in dynamics crm 2011

I am new to CRM and trying to write a plugin.

It's should be simple, but it's not.

For some reason I can't retrieve entity. I know for sure that it is exists in database and ID is correct.

The code below....

Does anyone has any ideas why it is not working? Thanks

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Microsoft.Xrm.Sdk;
using System.ServiceModel;
using Microsoft.Xrm.Sdk.Query;
using System.Collections;

namespace Copy_field
{
    public class Copy_field : IPlugin
    {
        /// <summary>
        /// A plugin copyies fields from Contact Entity to Case Entity. This allows display
        /// information about the client on case Entity and change it directly from Case Entity 
        /// </summary>
        /// <remarks>Register this plug-in on the Create case, update case and update of contact
        /// </remarks>
        /// 

        public void Execute(IServiceProvider serviceProvider)
        {
            IPluginExecutionContext context = (IPluginExecutionContext) serviceProvider.GetService(typeof(IPluginExecutionContext));

            ITracingService tracer = (ITracingService)serviceProvider.GetService(typeof(ITracingService));
            IOrganizationServiceFactory serviceFactory = (IOrganizationServiceFactory)serviceProvider.GetService(typeof(IOrganizationServiceFactory));
            IOrganizationService service = serviceFactory.CreateOrganizationService(context.UserId);

            Entity entity;

            if (context.InputParameters.Contains("Target") && context.InputParameters["Target"] is Entity)
            {

                entity = (Entity)context.InputParameters["Target"];
                if (entity.LogicalName != "incident") { return; } 
            }
            else
            {
                return;
            }
        //    tracer.Trace("1. THIS IS an/a: " + entity.LogicalName);
          //  tracer.Trace("2. Id: " + entity.Id);
   //         tracer.Trace("2.2 output parametersId: " + context.OutputParameters["id"].ToString());

            // if record exists - retrieve the entity

            ///////////////////////////////////////////////////////////////////
        ColumnSet cols = new ColumnSet(true);
        Entity yahhooo = service.Retrieve(entity.LogicalName, entity.Id, cols);


        }
    }
}

don't forget that in update message , you only access to filed's that you update(change) it... you can write as in the following method to trace your code(line to line)

  public static void LogFile(string log)
    {
        try
        {
            TextWriter tw = new StreamWriter(@"C:\Inetpub\wwwroot\inventorylog_" + Guid.NewGuid() + ".txt");
            tw.Write(log);
            tw.Close();
        }
        catch
        {
        }
    }

Be successful

Well, you could give us a little bit more of information about it like, is it throwing any exception? My guess is that you are getting the following error: "The "yourentity" with id "yourentityid" does not exist in the database", if so you may be trying to retrieve a record on it's create on Pre-Operation pipeline. Anyway, help us help you giving us more information.
