Activator.CreateInstance can't find the constructor (MissingMethodException)

Question

I have a class which has the following constructor

public DelayCompositeDesigner(DelayComposite CompositeObject)
{
    InitializeComponent();

    compositeObjec         


        

Answer 1

I would think that your call would need to be:

var designer = Activator.CreateInstance(designerAttribute.Designer, new object[] { new DelayComposite(4) });

Unless, of course, it is that, in which case the answer is not immediately obvious.
