I'm trying to continue working on my plugins for AutoCAD in Visual Studio 2013. I opened up my project files and all the references to Autodesk libraries were missing. To remedy this, I added references to the following dll files from ObjectARX 2015 shown in the dlls image attached. I am using the following Autodesk namespaces:
using Autodesk.AutoCAD.ApplicationServices;
using Autodesk.AutoCAD.DatabaseServices;
using Autodesk.AutoCAD.EditorInput;
using Autodesk.AutoCAD.Geometry;
using Autodesk.AutoCAD.Runtime;
Adding the missing references makes the errors go away until I try to test my program at which point I get new errors underlining Autodesk references in gray instead of red as shown in the attached image. I have no idea why the added references are not working. It may also be worth knowing I've migrated from Visual Studio 2012 to Visual Studio 2013 and AutoCAD 2014 to AutoCAD 2015
