When I first heard about Windows Workflow Foundation, I wasn’t particularly excited. “Workflow” has long been a buzzword used by vendors, product managers, and venture capitalists in mind numbing phrases like: “Our workflow solution will leverage your strategic business assets and put you in the fast lane of the information superhighway”.
Nevertheless, I knew some people who were taking Workflow seriously, so I decided to give the preview bits a try. Workflow is a success. The designer works well – both the user interface and the programming interface are intuitive. For a good description of the feature set, which includes state machine workflows and long running workflows, see David Chappell’s “Introducing Windows Workflow Foundation”.
Here is a code activity that Workflow invokes. It would be nice if the Parameters turned into strongly typed properties.
private void Fetch_ExecuteCode(object sender, EventArgs e)
FetchSettings settings = new FetchSettings();
settings.ConnectionString = Parameters["ConnectionString"].Value as string;
settings.LocalDataPath = Parameters["LocalDataPath"].Value as string;
processor = new FetchProcessorFactory.GetConfiguredFetchProcessor(settings);
_files = processor.Process();
To kick off a workflow...
private void StartImport()
Type importType = typeof(ImportWorkflow);
Dictionary<string, object> parameters = new Dictionary<string, object>();
