An attempt to call Load on a target application domain that is not the current application domain will result in a successful load of the assembly in the target application domain. Since an Assembly is not MarshalByRefObject, when this method attempts to return the Assembly for the loaded assembly to the current application domain, the common language runtime will try to load the assembly into the current application domain and the load might fail. The assembly that is loaded into the current application domain might be different from the assembly that was loaded first if the path settings for the two application domains are different.
