Addins written for V20 or later, it is preferred to implement this interface rather than ISEAddIn.

A very important reason for this new interface is the lone method, SetAddInInfoEx that takes in a resource module filename as opposed to a module handle. This allows an addin to transmit resources to Edge for both 32 and 64 bit versions of edge. A failure to use the new interface will cause issues on 64 bit edge.
