I installed VS2012 and tried to open a project that was developed using VS2012 as well by another developer. But I am getting an error message as below. I googled the error message and found most of MVC projects have same problem and found solutions to those. But mine isn't a MVC project. The original developer said it is a Light Switch and Entity Framework project. How can I start trouble shooting to find out what I am missing on my computer and to solve this problem?
This just happened to me too. I was missing "Microsoft SQL Server Data Tools - Business Intelligence for Visual Studio 2013". Once I downloaded that, I had additional Business Intelligence Project types when going to File -> New -> Project that I didn't have before, and I was able to open the Solution.
So maybe compare the project types you and your developer friend have listed when you go to File -> New -> Project.
