I'm trying to work on the same C# .NETCore codebase in both VS for mac and regular VS Enterprise 2015 (Windows).
I made a .NETCore app in VS for Mac and tried to open the project in VS for Win, but the one-way project upgrade dialog appears in VS for Win, so no multiplatform development joy? (After accepting the dialog to do a one-way upgrade, my Program.cs file does not appear in the Project Explorer... wtf)
Also tried to open an ASP.NET MVC project (made in VS for mac) on Windows VS, that worked (and back)!
How do you go about this?
