crm 2011 Unable to cast object of type 'System.Guid' to type 'Microsoft.Xrm.Sdk.EntityReference

The code below creates a set of records from an entity I use to hold "template" records. I loop through the templates and create records which works including the lookup fields where I use an EntityReferenceentity. But when I use an EntityReference to create a relationship back to the parent entity record I get this error.

crm 2011 Unable to cast object of type 'System.Guid' to type 'Microsoft.Xrm.Sdk.EntityReference'

            foreach (var template in templateSteps.Entities)
            {
                Entity step = new Entity("img_workflowmanager");
                step["subject"] = template["img_name"];

                if (step.Contains("img_poststepid"))
                {
                    step["img_poststepid"] = (EntityReference)template["img_poststepid"];
                }
                if (step.Contains("img_prestepid"))
                {
                    step["img_prestepid"] = (EntityReference)template["img_prestepid"];
                }

                step["img_workflowstepsid"] = (EntityReference)postMessageImage["img_procurementpackageid"];
                this._orgService.Create(step);
            }

The message is clear, postMessageImage["img_procurementpackageid"] contains a Guid and not an EntityReference.

Assuming the entity name is img_workflowsteps you can write

Guid packageId = (Guid)postMessageImage["img_procurementpackageid"];
step["img_workflowstepsid"] = new EntityReference("img_workflowsteps", packageId);

By the way, the first two if conditions will be never executed, because when you create an entity with that syntax, no attributes are defined.
