I've recently had some trouble loading the ProjFS dll, and was experiencing a System.IO.FileNotFoundException trying to find the dll (in Visual Studio 2022). Following the instructions in the README for dealing with BadImageFormatExceptions (i.e., adding the UseIJWHost tag to my project) worked for me, even though I had never seen a BadImageFormatException. Perhaps the README could be updated to indicate that these steps can also help with FileNotFoundExceptions.
