How do I associate a workflow to a custom list in Visual Studio 2010?

Question

I created a Sharepoint 2010 Sequential Workflow in a Visual Studio 2010 project. But I didn't found a way to associate it to one of my list. Every time I deploy to the site, I have to manually associate it with the good list.

The list is also created in the VS 2010 project.

Is there a way to associate my workflow to a list to be invoked every time an item is created or updated ?

Thanks

If you would like to associate workflow with the specific list when you deploy you solution by VS2010, you can select workflow, choose element property ans set Target List.

SPWorkflowTemplate baseTemplate =                                        currentSite.RootWeb.WorkflowTemplates.GetTemplateByName
                                                ("workflow", CultureInfo.InvariantCulture);
                                        SPWorkflowAssociation workflowAssociation =
                                            SPWorkflowAssociation.CreateListContentTypeAssociation(
                                                baseTemplate,
                                                "description",
                                                currentWeb.Lists["Tasks"],
                                                currentWeb.Lists["History"]);
                                        workflowAssociation.AllowManual = true;
                                        workflowAssociation.AutoStartChange = false;
                                        workflowAssociation.AutoStartCreate = false;
                                        siteContentType.WorkflowAssociations.Add(
                                            workflowAssociation);
                                        liste = currentWeb.Lists;
                                        foreach (SPList list in liste)
                                        {
                                            if (list.ContentTypes[0].Name == "ct")
                                            {
                                                list.WorkflowAssociations.
                                                    UpdateAssociationsToLatestVersion();
                                            }
                                        }

For adding to a specific content type. For lists should be the same. Good luck !
