I installed ArcGIS 10.4.1 and VS 2015. Then I found out there is no Add ArcGIS reference in Reference context menu. I installed VS 2013 on the same computer. When I had ArcGIS 10.3.1 installed I had Add ArcGIS reference. However after I uninstalled ArcGIS 10.3.1 and installed ArcGIS 10.4.1 Add ArcGIS Reference in VS 2013 is lost too.
Thanks in advance.
