Different Plugin CRM 4 and CRM 2011

1) References We no longer use the Microsoft.Crm.* DLLs, as the namespace had a complete makeover. MS CRM 2011 introduced a brand new namespace “XRM”, hence the DLLs to use are Microsoft.Xrm.* Since the changes in MS CRM 2011 SDK are using WCF based services (compared to the web services used by its predecessor), we must reference the below mentioned: o System.ServiceModel o System.Runtime.Serialization A reference to the “Microsoft.IdentityModel” DLL is a must if the plugin is targeted at MS CRM 2011 online version. 2) Executing Execute method now uses IServiceProvider.

CRM 4.0	CRM 2011
public void Execute(IPluginExecutionContext context)	public void Execute(IServiceProvider serviceProvider)

3) IPluginExecutionContext Similar to the “Execute” method retrieving the context object inside a plugin also changed: IPluginExecutionContext context = (IPluginExecutionContext)serviceProvider.GetService(typeof(IPluginExecutionContext));   4) CRM Service In CRM 2011, ICrmService is replaced by IOrganizationService CRM 4.0 CRM 2011 ICrmService _CS = context.CreateCrmService(true); IOrganizationServiceFactory factory = (IOrganizationServiceFactory)serviceProvider.GetService(typeof(IOrganizationServiceFactory)); IOrganizationService service = factory.CreateOrganizationService(context.UserId); 5) DynamicEntity has been changed to Entity CRM 4.0 CRM 2011 if ((context.InputParameters.Properties.Contains(“Target”) == true) && (context.InputParameters.Properties["Target"] is DynamicEntity)) { } if (context.InputParameters.Contains(“Target”) && context.InputParameters["Target"] is Entity) { } Similarly “Properties” of a CRM entity now have to be accessed using the “Attribute” collection: entity.Attributes.Contains("new_incidentnumber")

Below given template can be used to create a plugin for the MS CRM 2011 using System; using System.ServiceModel; using System.Runtime.Serialization; using Microsoft.Xrm.Sdk; using Microsoft.Xrm.Sdk.Query; using Microsoft.Xrm.Sdk.Messages; namespace MyPlugin { public class MyPlugin : IPlugin { public void Execute(IServiceProvider serviceProvider) {  IPluginExecutionContext context = (IPluginExecutionContext)serviceProvider.GetService(typeof(IPluginExecutionContext));  if (context.InputParameters.Contains("Target") && context.InputParameters["Target"] is Entity) {  Entity entity = (Entity)context.InputParameters["Target"];  if (entity.LogicalName != "entity logical name”)  { return; } try { IOrganizationServiceFactory factory = (IOrganizationServiceFactory)serviceProvider.GetService(typeof(IOrganizationServiceFactory)); IOrganizationService service = factory.CreateOrganizationService(context.UserId); //Plugin Code  } catch (FaultException ex)  { throw new InvalidPluginExecutionException("An error occurred in the plug-in.", ex); } } } } }
