To apply order to the way you work with multiple assemblies, and also to support switching between different sets of assemblies, ReSharper organizes assemblies and folders into assembly lists. You can work with different assembly lists depending on your context. You can save and reopen assembly lists, or clear the current list if you no longer need it.

To load a saved assembly list
When you expand an assembly in the Assembly Explorer Window, you can see the list of referenced assemblies under the References node. The referenced assemblies do not expand further; however, you can explore them by adding to the root level of the Assembly Explorer.
