No way to merge resources files while duplicate Resources classes can be merged with /union

[lextm]

If two assemblies happen to use the same default namespace, their resources.resx files will generate two Resources classes which can be merged by using /union switch.

However, the generated .resources in both assemblies after merge won't be able to be merged together. /allowduplicateresources switch only leaves two .resources in the output assembly, and it does not help at all.

Sounds fair, we should merge the binary resources as well.
To support this properly, one shouldn't have to enable /union, as the scope of this conf is too wide, I'd think to automatically merge resources with same name, it can't hurt.
