I have created a custom composite activity that derived from the Activity
and IActivityTemplateFactory. When I try to deploy this composite activity as a
root activity on the rehosted application. It failed to display its designer probably. If I put a sequence as a root activity, and the composite activity as a child activity inside the sequence activity, I got my composite activity designer
display nicely on my rehosted designer. Is it a limitation for us to put a IActivityTemplateFactory designer as root activity in the rehosted app. Please advice.
public class CustomCompositeActivity : Activity, IActivityTemplateFactory
public Activity Create(System.Windows.DependencyObject target)
return new Sequence
Text = "Hello"
Text = "WF 4.0"
