Referencing assemblies in GAC

I found out that you can't actually refer to assemblies from the GAC directly. So in development, you need to add reference to the physical assemblies (wherever that assemblies are located), set "Copy Local" to false and at run time, the CLS will load the assembly reference from the GAC.
