public void AddCodeActivityToDesigner()
{
    WorkflowDesignerLoader loader = GetService(typeof(WorkflowDesignerLoader)) as WorkflowDesignerLoader;
    if (loader == null)
        return;

    IDesignerHost designerHost = (IDesignerHost)GetService(typeof(IDesignerHost));
    CompositeActivity rootActivity = designerHost.RootComponent as CompositeActivity;

    CodeActivity codeActivity = new CodeActivity();
    rootActivity.Activities.Add(codeActivity);
    loader.AddActivityToDesigner(codeActivity);
    return;
}

Public Sub AddCodeActivityToDesigner()

    Dim loader As WorkflowDesignerLoader = CType(GetService(GetType(WorkflowDesignerLoader)), WorkflowDesignerLoader)
    If loader Is Nothing Then Return
    Dim designerHost As IDesignerHost = CType(GetService(GetType(IDesignerHost)), IDesignerHost)
    Dim rootActivity As CompositeActivity = CType(designerHost.RootComponent, CompositeActivity)
    Dim codeActivity As New CodeActivity()
    rootActivity.Activities.Add(codeActivity)
    loader.AddActivityToDesigner(codeActivity)
    Return
