Is it possible to install an assembly into the GAC as some sort of 'linked assembly'?

Question

Hello,

I'm trying to deploy some sort of framework and therefore need to register some assemblies in the GAC.

The interesting part is: These GAC assemblies should only be used by the framework developer, the client apps should not use these GAC assemblies but the ones in their local directories (the GAC assemblies could be of a different version, most likely higher).

I've already found and tried the app.config setting but it seems to be ignored by the client app (latest .NET runtime installed is 3.5).

Any ideas on how to solve this issue?

Thanks for help!
