How to programatically associate a workflow with a list

I needed to do this in a previous project where we created a custom workflow and needed to associate that workflow with a list that existed within a SharePoint site.

We used a site definition that provisioned a pages library, and activated the workflow feature each time a site was created.

However it was still a manual step to associate the workflow with the pages library. To solve this we created a site feature receiver that ran when the site was created and called the following code.

 
public override void FeatureActivated(SPFeatureReceiverProperties properties)
{
   using (SPWeb siteWeb = (SPWeb)properties.Feature.Parent)
   {
      SPList list = siteWeb.Lists["Name here"];
      SPWorkflowTemplate baseTemplate = 
                                     siteWeb.WorkflowTemplates["Workflow Guid"];
   
      SPWorkflowAssociation assoc = SPWorkflowAssociation.CreateListAssociation(
                                       baseTemplate
                                       , "NameOfWorkflow"
                                       , "SPList task list"
                                       , "SPList history list");
 
      list.AddWorkflowAssociation(assoc);
   }
}
