.net Resource compiles not second language

Friendly hello to everyone.

I’ve created an .net class library for oxygene. Only using the included Properties.Resources.resx and create an new Resource file Resources.de.resx. Fills in some strings and compile it.
But the result directory shows no de subdirectory with the dll for the german resources.
When I do the same with c# there is the expected subdirectory and dll.
