Dynamically loaded assembly showing form?

Question

Hi.

Is there a way to allow an instance of a class from a dynamically loaded assembly to show a form?

I have this plugin system which loads assemblies in separate domains (for unloading them as needed). These assemblies might have settings, and I was hoping I could have each assembly present a form to the end user to allow for editing them. Each extension in an assembly needs to implement a special interface just for this. However, on showing the form from my plugin manager class, I get an exception that the Form class isn't serializable. Apart from deriving from Form and implementing ISerializable myself, is there another way to do this?

Tx for any hints, tips, and (hopefully :D) solutions! ...Arjan...

Answer 1

The serialization issue is because the Form class isn't Marshal by reference and you're trying to invoke a method on the class across domains. If the only form they need to show is for user settings, you might be better of defining some sort of "settings" class that is passed between the plugins.
