What’s new in CRM 2011 plugins ?

I wrote a plugin to cascade changes from account addresses to their child contacts in 2011 then converted it back to v4. Let’s look at some of the differences I found.

CRM v4

public void Execute(IPluginExecutionContext context) {
  DynamicEntity target = (DynamicEntity)context.InputParameters[ParameterName.Target];
    if (target.Name.Equals("account")) {
      if (target.Properties.Contains("accountid")) {

CRM 2011

public void Execute(IServiceProvider serviceProvider) {
  IPluginExecutionContext context = (IPluginExecutionContext) serviceProvider.GetService(typeof(IPluginExecutionContext));
  Entity target = (Entity)context.InputParameters["Target"];
    if (target.LogicalName.Equals("account")) {
      if (target.Attributes.Contains("accountid")) {

• Getting the context and target is slightly more complex.
• .Properties has become .Attributes.

 

CRM v4

QueryByAttribute query = new QueryByAttribute();
query.EntityName = "account";
query.Attributes = new string[] { "accountid" };
query.Values = new Object[] { accountid };
query.ColumnSet = cols;

CRM 2011

QueryByAttribute query = new QueryByAttribute();
query.EntityName = "account";
query.Attributes.AddRange("accountid");
query.Values.AddRange(accountid);
query.ColumnSet = cols;

• Queries no longer require string or object arrays

 

CRM v4

ICrmService service = context.CreateCrmService(false);
RetrieveMultipleRequest req = new RetrieveMultipleRequest();
req.Query = query;
req.ReturnDynamicEntities = true;
RetrieveMultipleResponse resp = (RetrieveMultipleResponse)service.Execute(req);
BusinessEntityCollection theAccounts = resp.BusinessEntityCollection;
if (theAccounts.BusinessEntities.Count > 0) {
  DynamicEntity theAccount = (DynamicEntity) theAccounts.BusinessEntities[0];

CRM 2011

IOrganizationServiceFactory serviceFactory = (IOrganizationServiceFactory)serviceProvider.GetService(typeof(IOrganizationServiceFactory));
IOrganizationService service = serviceFactory.CreateOrganizationService(context.UserId);
RetrieveMultipleRequest req = new RetrieveMultipleRequest();
req.Query = query;
RetrieveMultipleResponse resp = (RetrieveMultipleResponse)service.Execute(req);
EntityCollection theAccounts = resp.EntityCollection;
if (theAccounts.Entities.Count > 0) {
  Entity theAccount = theAccounts.Entities[0];

• Accessing the service is done through a Factory class
• No longer have to specify that you want dynamic entities
• BusinessEntities have just become Entities
• Treat dynamic entities the same as any other entity

 

CRM v4

TargetUpdateDynamic update = new TargetUpdateDynamic();
update.Entity = theContact;
UpdateRequest updatereq = new UpdateRequest();
updatereq.Target = update;
UpdateResponse updateresponse = (UpdateResponse)service.Execute(updatereq);

CRM 2011

UpdateRequest updatereq = new UpdateRequest();
updatereq.Target = theContact;
UpdateResponse updateresponse = (UpdateResponse)service.Execute(updatereq);

• No longer a need for a TargetUpdateDynamic object

 

CRM v4

Guid accountid = ((Key)target.Properties["accountid"]).Value;
CrmBoolean trigger = (CrmBoolean)theAccount.Properties[accountTrigger];

CRM 2011

Guid accountid = (Guid)target.Attributes["accountid"];
bool trigger = (bool)theAccount.Attributes[accountTrigger];

• Native C# data types, WOO!
