Visual studio not copying content files from indirectly referenced project

Question

I have the following project structure:

Library1 <--[project reference]-- Library2 <--[ref]-- Executable
--------                          --------             


        

Answer 1

Could be that you reference Library1 only from an XAML file in that case Visual Studio dont recognice the usage. Add a reference in code as well e.g. by applying the name attribute
