// Obtain the tracing service
ITracingService tracingService =
(ITracingService)serviceProvider.GetService(typeof(ITracingService));

// Obtain the execution context from the service provider.  
IPluginExecutionContext context = (IPluginExecutionContext)
    serviceProvider.GetService(typeof(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"];

    // Obtain the organization service reference which you will need for  
    // web service calls.  
    IOrganizationServiceFactory serviceFactory =
        (IOrganizationServiceFactory)serviceProvider.GetService(typeof(IOrganizationServiceFactory));
    IOrganizationService service = serviceFactory.CreateOrganizationService(context.UserId);

    try
    {
        // Plug-in business logic goes here.  
    }

    catch (FaultException<OrganizationServiceFault> ex)
    {
        throw new InvalidPluginExecutionException("An error occurred in FollowUpPlugin.", ex);
    }

    catch (Exception ex)
    {
        tracingService.Trace("FollowUpPlugin: {0}", ex.ToString());
        throw;
    }
}
