Long Running Activity example

  • Artikel

In the Windows Workflow Foundation hands on labs there is an example of an activity which takes a lot of processing power. It's in Lab 5 Exercise 4 in the WF Beta 2 HOLs. The mechanism used is to have a CallExternalMethod activity followed by a HandleExternalEvent activity. The action requiring processor time is executed on a separate thread.

In this sample activity only one activity is required which starts the work and also waits for it to finish by returning the ActivityExecutionStatus.Executing state from the activity.
