>Is there a way to view base class code and set breakpoints of objects that are derived from classes in assemblies not in the solution being edited in VS? The Class Viewer has a “Go To Definition” menu option that will navigate to base code of a selected node but it is disabled if the code is in another assembly. This is reasonable since VS can only edit one solution at a time but is there another way to navigate directly to code in another solution?

You need the soruce code to debug the source obviously. You can debug the code if you have it by opening the class and setting a break point manually in that code. I should fire the debugger on this code as long as Debug info is provided in the compiled dll.
