Allowing add-ins in your own VB.Net application

[Steve McQuillan]

How do I allow add-ins in my own custom made VB.Net
application. Most of the major companies allow it and I
wish to promote a controlled way of installing plug-ins.

The application I am developing will probably need a few
plug-ins and it would be handy to have this functionality
(a tutorial of some description would be ideal)

One way to go about it is to provide an interface that others would
implement. Your program then instantiates objects that the others provide,
casts them to the type of the interface, and calls their methods through the
interface.
