Don't.

There are problems with even trying, such as circular references: since your Main form needs to reference your class library (in order to access your "talent" code) you can't add a reference to your Main project to your "talent" project without setting up a circular reference which would mean that your project could never compile (as any change to the Main project means the talent needs to be rebuilt, which causes the main to need rebuilding, which means that talent needs to be rebuilt, and so on.

And logically, it wrong as well - your DLL shouldn't need to know anything about the presentation layer at all! If it does, you can't replace a layer at a later date, which is a bad idea.

Instead, look at creating events in the library which the form handles to provide information to the library when it needs it.
