Is it possible to have a resource dictionary in a WPF class library assembly (.dll)? I ask this because I have an "Application WPF" assembly (.exe), if I try to turn the type of the assembly to "WPF Class Library" I get the error:
Impossible to specify the element ApplicationDefinition in the project file of the Library
How can I make it work?
You get that error because one of your XAML files
has a Build Action
set to ApplicationDefinition
. Usually, that is App.xaml
. Remove that file or change it's Build Action
from Properties Window
to Page
to stop getting that error.
This will be the build action of one of your XAML files. I would use a WPF User Control Library or WPF Custom Control Library instead of a general class library.
