This question is just a reference to myself and to whomever gets here while searching for a solution to this issue.

The Copy Local in the reference was set to True but the DLL was not copied to the build folder.

Since I used this resource library only in XAML, I had to add a using statement:

using ResourceLibrary;

in the referencing code (actually, the code that called the referencing code, which was either the app or the unit-test)

This made the DLL created in the destination build directory.

Edit:

Sometimes even using ResourceLibrary doesn't work. The solution is creating some empty static method in the code-behind of the ResourceLibrary:

namespace ResourceLibrary {
    public static class ReferencePoint {
        public static ReferToMe() {}
    }
}

And calling it from the referencing code:

ReferencePoint.ReferToMe();

This is a valid answer, I had a unit test failing with a similar exception. Simply adding the required dlls to the test project fixed the issue. Resharper would fail the test but NCrunch would pass it.

This happened to me because the app that started when I ran had a reference to a DLL in a different location that was old.

The actual project that used it had the right reference, but the starting app had the wrong one and therefore it was using that old DLL.

To solve this, I deleted the reference on the starting app and added it again to point to the correct location.

I fixed this by setting the debug platform to 64 bit, same as the reference setting
