Perché il mio programma non sembra nel GAC per un assembly?

Domanda
Ho un servizio che carica un mucchio di assiemi come plugin. Ognuno di questi plugin fa riferimento a un gruppo comune installato nel GAC. Per qualche ragione, alcuni plugin sono in grado di caricare correttamente l'assemblaggio dal GAC, ma altri falliscono. Non riesco a capire perché ciò accada. Ecco il registro di fusione per uno che funziona e su questo no:

Soluzione
L'assemblea fallita non è fortemente firmata (publickey = null). Non so perché l'assemblaggio non sia firmato, ma non è necessario che il caricatore cerchi nel GAC per tale assemblaggio poiché solo gli assiemi fortemente firmati possano andare nel GAC.
