You cannot get an instance out of a type simply by casting. When you cast,
you always cast a reference to an instance, like so:

    object obj = new SomeClass();
    // Now cast 'obj' to a reference to 'SomeClass'
    SomeClass sc = (SomeClass)obj;

Btw, there are a number of articles on the net that show how to create a
pluggable architecture. I know there is one on www.codeproject.com (I can't
seem to access it now). There's another one written in VB.NET on
developerfusion.com: http://www.developerfusion.com/show/4371/ .

I also wrote a quick C# sample that shows one way of doing a pluggable
architecture. It is very similar to the articles above. My sample is
available for download at http://www.capehill.net/pluginsample.zip . I might
add some security specific stuff to this sample later if I have the time...
