Load a ResourceDictionary from an assembly

Question

I've got an assembly somewhere on the file system, e.g. "C:\temp\test.dll". In that assembly there's a ResourceDictionary, e.g. "abc.xaml".

How can i get that ResourceDictionary? Maybe there is a way using Reflections? I didn't find a solution so far.

Thanks in advance!

Edit: Just wanted to add that I want to access the Resources in the Dictionary, e.g. a Style.
