MSCRM 2011 early binding plugin

Checked on MSCRM 2011 on premise and online.

*** I think it's important to understand what is going behind the scenes, here's easier option for creating plugin with early binding. It's done using Dynamics CRM 2011 developer toolkit.

When i've tried to follow the sdk:

"Walkthrough: Build a Plug-in That Connects to Microsoft Dynamics CRM 2011 Using Developer Extensions"
I've ended up looking the web for a way to register plugin which refernced Microsoft.Xrm.Client.dll,
The plugin registration tool kept given me errors because it couldn't find Microsoft.Xrm.Client.dll
Could not load file or assembly 'Microsoft.Xrm.Client, Version=5.0.9688.1154, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified.

All the solution in the web suggested to use ILMerge for merging the plugin assembly with the 

Microsoft.Xrm.Client.dll and many other not intuitive solutions.

WTF?!?! There most be easier why to enjoy the early binding with out all this mess.

It's possible, just follow these steps:

1) create the xrm class using CrmSvcUtil
Example:

CrmSvcUtil.exe /out:Xrm.cs /url:http://crm2011:5555/Basic/XRMServices/2011/Organization.svc /username:yyyyy /password:xxxxx /namespace:Xrm/serviceContextName:XrmServiceContext 

2) Add the created file to the project
3) Add reference to the project
microsoft.xrm.sdk.dll
microsoft.crm.sdk.proxy.dll
4) inherit IPlugin

This is it.

this is how you get the context:

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

                XrmServiceContext xrm = new XrmServiceContext(service);

Example for the plugin:

public class SLAPlugin : IPlugin
    {
        public void Execute(IServiceProvider serviceProvider)
        {
            IPluginExecutionContext context = (IPluginExecutionContext)
serviceProvider.GetService(typeof(IPluginExecutionContext));
            Entity entity;
            // Check if the input parameters property bag contains a target
            // of the create operation and that target is of type Entity.
            if (context.InputParameters.Contains("Target") &&
            context.InputParameters["Target"] is Entity)
            {
                // Obtain the target business entity from the input parameters.
                entity = (Entity)context.InputParameters["Target"];

                // Verify that the entity represents a contact.
                if (entity.LogicalName != Incident.EntityLogicalName) { return; }
            }
            else
            {
                return;
            }

            try
            {
                IOrganizationServiceFactory serviceFactory =
                    (IOrganizationServiceFactory)serviceProvider.GetService(
                typeof(IOrganizationServiceFactory));
                IOrganizationService service =
                serviceFactory.CreateOrganizationService(context.UserId);

                XrmServiceContext xrm = new XrmServiceContext(service);
                
                // Extract the tracing service.
                ITracingService tracingService = (ITracingService)serviceProvider.GetService(typeof(ITracingService));
                if (tracingService == null){
                    throw new InvalidPluginExecutionException("Failed to retrieve the tracing service.");
                }

                if(!context.PostEntityImages.Contains("MyImage")){
                    throw new InvalidPluginExecutionException("Failed to retrieve the Post Image.");
                }

                Entity postEntity = context.PostEntityImages["MyImage"];
                Incident caseTemp = postEntity.ToEntity<Incident>();

                if (caseTemp != null)
                {
                    //only if missing active conditionset start looking for one
                    if (caseTemp.new_ActiveCoditionSetId == null)
                    {
                        tracingService.Trace("Start looking for conditionset");
                        MSCRM2011SLAProcessWorker a = new MSCRM2011SLAProcessWorker();
                        a.GetConditionSetAndUpdateCase(xrm, tracingService,caseTemp);
                    }
                }
            }
            catch (FaultException<OrganizationServiceFault> ex)
            {
                throw new InvalidPluginExecutionException(
                "An error occurred in the plug-in.", ex);
            }
        }
    }

Updating newly created entity that is not in the context

//create update case
Incident caseToUpdate = new Incident
{
 IncidentId = activeCase.IncidentId
};
//update the update case
xrm.Attach(caseToUpdate);
xrm.UpdateObject(caseToUpdate);
xrm.SaveChanges();
    

Hope it helps...
