I am always interested in articles describing the differences between developing in CRM 4 and CRM 2011. This is a common problem I have and it actually works both ways.
To start with I was trying to convert code examples in Javascript and Plugins from CRM 4 to CRM 2011 and finding that we use Entity instead of DynamicEntity etc. The Javascript is completely different so I’m not going to mention that but if you want to know click the link below.
I also find myself getting confused when I have to do some coding in CRM 4 because I get used to working CRM 2011 and then I have to remember how to do things in CRM 4 again…
Now today I found this article explaining the differences between custom workflows in CRM 4 and CRM 2011, it’s an excellent article and the original can be found here but I have pasted the full article below because I would like it for my own reference
We have listed the list of changes noticed for designing a custom workflow assembly in CRM 2011 and in CRM 4.0.
1. References
CRM 4.0
using System.Workflow.Activities;
using System.Workflow.ComponentModel;
using System.Workflow.ComponentModel.Compiler;
using Microsoft.Crm.Sdk;
using Microsoft.Crm.Sdk.Query;
using Microsoft.Crm.SdkTypeProxy;
using Microsoft.Crm.Workflow;
CRM 2011
using System.Activities;
using Microsoft.Crm.Sdk.Messages;
using Microsoft.Xrm.Sdk;
using Microsoft.Xrm.Sdk.Workflow;
2. Base Class
Base class definition has been changed from SequenceActivity to CodeActivity.
CRM 4.0: In CRM 4.0 we have to specify both Workflow name and Workflowactivitygroupname in the code as written in the following code.
[CrmWorkflowActivity(“My Custom Workflow”, “CRM Workflow”)]
public class MyCustomWF: SequenceActivity
CRM 2011: In CRM 2011 that is done in different way.
public class MyCustomWF: CodeActivity
Both Workflow name and Workflowactivitygroupname can be specified at the time of registering the assembly as shown in below screen shot.
3. Execute Method
The overridden Execute method remains the same except parameter and return type.
CRM 4.0
protected override ActivityExecutionStatus Execute(ActivityExecutionContext executionContext)
CRM 2011
protected override void Execute(CodeActivityContext executionContext)
4. Create service
CRM 4.0
IContextService contextService = (IContextService)executionContext.GetService(typeof(IContextService));
IWorkflowContext context = contextService.Context;
ICrmService crmService = context.CreateCrmService();
CRM 2011
IWorkflowContext context = executionContext.GetExtension<IWorkflowContext>();
IOrganizationServiceFactory serviceFactory = executionContext.GetExtension<IOrganizationServiceFactory>();
IOrganizationService service = serviceFactory.CreateOrganizationService(context.UserId);
5. INPUT Parameters
CRM 4.0
Declaration: how to initialize the input parameter
// specified dependency property
public static DependencyProperty CaseIDProperty = DependencyProperty.Register(“CaseID”, typeof(Lookup), typeof(TotalTaskRetrieval));
// Specified Input property
[CrmInput(“Enter Case “)]
// Set the reference Target for Property created
[CrmReferenceTarget(“incident”)]
// Property Defined for caseId
public Lookup CaseID
{
get
{
return (Lookup)base.GetValue(CaseIDProperty);
}
set
{
base.SetValue(CaseIDProperty, value);
}
}
Use: Access the input parameter declared above as,
Guid caseid=CaseID.Value
CRM 2011
Declaration: how to initialize the input parameter
[Input(“Enter Case “)]
[ReferenceTarget(“incident “)]
[Default(“3B036E3E-94F9-DE11-B508-00155DBA2902″, ” incident “)]
public InArgument<EntityReference> CaseID { get; set; }
Use: Access the input parameter declared above as,
Guid caseid = CaseID.Get<EntityReference>(executionContext).Id
6. OUTPUT Parameters
CRM 4.0
[CrmOutput(“outputSum”)]
public CrmMoney Sum
{
get
{
return (CrmMoney)base.GetValue(SumProperty);
}
set
{
base.SetValue(SumProperty , value);
}
}
CRM 2011
[Output(“outputSum”)]
[Default(“23.3”)]
public OutArgument<Money> Sum { get; set; }
