Hello Blair, 

When you say start a SpaceClaim session through the Session class are you referring to a .NetRemoting call? Or something else?  

I will check what the session class does but in general the way to start Discovery is to provide a path to the executable and a manifest file to load add-ins. There is no need of any class to achieve this. 

Regards,

Devendra
