In the SDK docs there is a GetDomainNeutralAssemblies method defined for the
IHostControl interface. However, in the SDK headers the method does not exist.

I have an application where I would like to be able to load add-in's into
their own application domain and leave the host assemblies domain neutral.
GetDomainNeutralAssemblies would have worked perfectly for this. Are that any
other CLR Hosting interfaces that could be used to achieve this?
