After some more research I discovered the source of the issue. It is correct that all one has to import is the
*.cs file. The caveat lies in the project type. If working in a Class Library project, another step must be performed.
A. The files are only properly recognized after I performed these steps and then tried to open the file. Suddenly VS "wakes up" and fixes the files.
B. Order of the steps does not matter. If you already imported *.cs files, just fix the references.
C. If one is missing other references (E.G. DevExpress or other 3rd party Control imports), the *.cs files will not display properly until this has been resolved.
