I need to implement the method: object GetFactory(Type type); This method needs to return a Func<T> where typeparam 'T' is the 'type'. So, my problem is that I don't know how to create a Func<?> at runtime using reflection. Activator.CreateInstance doesn't work because there are no constructors on delegates. Any Ideas? ...
To be more specific: We have a web service (written in .Net) which utilizes a large number of COM dlls for core business logic (written in VB6). Assume for now that these are sealed libraries.

At least I think I have. My difficulty now is that the .net develo...
Hallo everybody, I'm dealing with a pretty strange situation here. I have developed a State Machine Workflow and it worked just fine until today.
