Using MonoGame, I've been trying to load content by using the commong Content.Load("Dir/contentfile"), and had success at first. I added my png files to the content directory, set them to build action 'Content', and set them to Copy If Newer.
After adding more content, however, I kept getting the "could not add as a non-content file" exception. I confirmed their build actions, cleaned, and rebuilt the solution with no luck. It is my understanding that this is possible (not compiling the content for MonoGame and using the png files), and also it worked correctly for some of the files.
I am using the Xamarin IDE. Google solutions have offered no help so far, any insights on things I could try? Is this simply a MonoGame issue?
