C# - Delete Some Class Files In Visual Studio, But Calling Them Still Works?

I am not sure if this is a problem with visual studio, but I had some class files that I deleted, but I can still call them in my code. Also I can call a .edmx i created, but I cant see it in my folder, i tried rebuilding my solution, cleaning it, rerunning it, checking source files. Its also causing a lot of my classes to have this error:Missing partial modifier on declaration of type 'MatchGaming.Models.MyProfile'; another partial declaration of this type exists I already tried adding partial and it i just get a bunch of errors everywhere else saying that a lot of my variables already contain a definition, almost like theres a duplicate class stuck in the cache or something.
