You might want to do this if you’ve got an assembly open, into which you’ve recompiled some changes. It’s pretty easy, just hit View > Refresh via the main menu, hit the corresponding Refresh button on the toolbar, or just press F5 on your keyboard. This should reload all assemblies in the list. Unfortunately at the moment it’s not possible to refresh an individual assembly, which we realise can be frustrating if you have a large number of assemblies in the list, however it’s on our list of possible enhancements.
