Yes, it is possible using some implementation of IFactory or generic IFactory. Please see this sample or this.

Yes, this is what I looking for.
Now I use nongeneric IFactory, with [Include(".*View$")] but I cannot filter some classes.
I have Forms and UserControls whose names end with View. How I can filter using base class instead of class name?
When I create a generic IFactory<T> where T : Form) I get There is no implicit reference conversion from SomeUserControlView to Form.

The "Include" filter works at compile time, but at run time you can perform additional filtering on already filtered types:

var val = factory();
if (val is BaseType) { }

This will work quite efficiently if you reduce the number of types at compile time, type checking is fast.
