Cannot find component 'file' of multifile assembly 'assembly'
One file in a multifile assembly could not be found. A multifile assembly references one or more files, such as modules or resource files.
The assembly being copied could be a direct reference, visible in the References node in Solution Explorer, or it could be an assembly that is a dependency of a direct reference.
To correct this error
Reinstall the component.
The project may build, but it might not run.
