Hello Everyone,

I'm using xaml activation to have a xaml only workflow with no compilation.  I've defined a base type of workflow (SequentialWorkflowActivity) that my xaml defined workflow derives from.  This works with no problems - the problem is that my base type of workflow has a designer defined and that designer is ignored.  One of the main reasons I want to define my own base type of workflow is to change how the workflow looks in the desiger...

Here is my base workflow definition...

[Designer(typeof(BaseWorkflowDesigner))]

public sealed partial class BaseWorkflow: SequentialWorkflowActivity

public BaseWorkflow()

Here is my base designer (some code has been omitted for space reasons)

[ActivityDesignerTheme(typeof(BaseWorkflowDesignerTheme))]

public class BaseWorkflowDesigner : SequentialWorkflowRootDesigner

public BaseWorkflowDesigner()

You need to use this:

[Designer(typeof(BaseWorkflowDesigner),typeof(IRootDesigner)]

There are two designers that can be associated with each Activity - an IDesigner and/or a IRootDesigner. You want the root designer because you are designer this activity *as* a Root.
