If you're seeing this error in a Windows Store / WinRT project:

I wasn't able to use the "pack://" syntax at all when trying to load a resource in my C# app. What worked was ms-appx:// syntax of this kind:

ms-appx://[project folder]/[resource path]

For example, I wanted to load a resource dictionary named "styles.xaml" from a folder "core". This URI ended up working for me:

dictionary.Source = new System.Uri("ms-appx:///core/styles.xaml");

Even though the question specified WPF, the problem seemed extremely similar but ended up having a completely different solution, which took a while to find, and existing answers didn't help at all.

Again, this solution does not apply to WPF
